Added tutorials covering these new features: Face analytics pipeline and a sample Face beautification algorithm. VideoCapture: waitAny API for camera input multiplexing Video4Linux through poll calls.

Implementation of Thread Local Storage TLS has been improved to release data from terminated threads. API has been changed. Python conversion rules of passed arguments will be updated in next releases: High-level API which introduces dnn::Model class and set of task-specific classes such dnn::ClassificationModel , dnn::DetectionModel , dnn::SegmentationModel.

It supports automatic pre- and post-processing for deep learning networks. There are Convolution, BatchNorm, Pooling, Eltwise layers implemented. Check Action recognition sample. Asynchornous inference support. Deep learning networks visualization diagrams using dot files cv::dnn::Net::dumpToFile. A lot of C API from OpenCV 1. x has been removed.

The affected modules are objdetect, photo, video, videoio, imgcodecs, calib3d. For now base64 support is not complete only loading baseencoded XML and YAML is supported, encoding is not supported at all. Also, the random access of sequences stored in a FileNode is now a slow O N operation vs. fast O 1 in the previous implementation; use cv::FileNodeIterator for much faster sequential access. On the positive side, the loaded FileStorage 's take x less memory than in the previous implementation.

Note that OpenCV 3. Now this is the only option so the flag is not needed and is not available anymore. Added support for Mask-RCNN model. Follow a guide and use a python sample. Integrated ONNX parser. We now support many popular classification networks. YOLO object detection network in partially supported as well ONNX version of YOLO lacks some final layers that actually give you the list of rectangles. Thanks to Lubov Batanina for her first-time contribution to OpenCV!

Further improved performance of DNN module when it's built with Intel DLDT support by utilizing more layers from DLDT. By the way, DLDT has been recently released as open-source. See the guide how to build and use OpenCV with DLDT support. API changes: by default, blobFromImage methods family do not swap red and blue channels and do not crop the input image. Beware that this API change has also been propagated to OpenCV 3.

Thanks to Zhiwen Wu and Juan J. Zhao for the contribution! Added shortcuts for the most popular deep learning networks supported by OpenCV. You may specify an alias name of model to skip pre-processing parameters and even paths to models! In example, instead of. Fixed OpenCL acceleration on AMD and NVIDIA GPUs. This is a mantenance release. New features are landed in OpenCV 4.

x development is switched from "master" to "3. x releases. We will merge changes from "3. Added support for quantized TensorFlow networks. We are now able to load 8-bit matrices of weights. The computations are still done in FP32 with plans to add FP16 path , but even now it's possible to compress the networks so that they consume less disk space.

For example, our face detector can be modified to read and use our 8-bit quantized ResNet-based face detection network pass it and this description file into cv::dnn::readNetFromTensorFlow. And the face detection network takes just 2. OpenCV is now able to use Intel DL inference engine as DNN acceleration backend. It gives quite noticeable performance boost on many models:. Added AVX acceleration to the performance-critical kernels, such as convolution and fully-connected layers.

SSD-based models trained and retrained in TensorFlow Object Detection API can be easier imported by a single invocation of python script making a text graph representation. Read a wiki page for details. That let us to increase performance of DNN inference quite significantly up to 6x on such machines. OpenCL backend has been expanded to cover more layers. The layer fusion has also been improved to increase the speed even further.

Several bugs in various layers have been fixed; in particular, SSD priors are now computed slightly differently so that we can more accurate bounding boxes when running SSD on variable-size images. The results of yet another GSoC OpenCV project on implementing new background subtraction algorithms have been integrated.

See the example for details. The partial Darknet parser, enough to parse YOLO models, as well as the layers to support a few variations of YOLO object detection networks have been integrated. See the corresponding sample. Preliminary support for FP16 networks has been added. We do not do computations in FP16 yet, we convert FP16 coeffs to FP32 when loading the networks. In the case of Caffe we rely on the following fork , whereas in the case of TF we use the official version.

Several new layers have been added to support text detection, image colorization and some other networks. OpenCV has been optimised for PPC64 bit PowerPC architecture by mapping the universal intrinsics to VSX. Big thanks to Sayed Adel for the patches. OpenCL acceleration path of the bioinspired module has been restored. On Iris Pro HD we get ~5x acceleration over the CPU branch. The regression tests have been expanded, some new tests have been added.

Now, there are 46 of them. Many bugs have been fixed in Torch and TF loaders, as well as in some processing layers. Now we check that on a certain set of networks the results from OpenCV DNN match or very close to the results from the original frameworks.

We also check that the results claimed in the papers for such networks are achievable with OpenCV DNN. Performance has been substantially improved. Layer fusion has been implemented and some performance-critical layers have been optimized using AVX, AVX2, SSE and NEON.

An external BLAS OpenBLAS, MKL, ATLAS is not needed anymore. The optional Halide backend has been added. It can accelerate OpenCV DNN on GPU when the GPU is fast enough. See Deep Learning in OpenCV for details about the module. Encoding and decoding of raw H. In some cases kernel recompilation will be needed. Long-awaited update to OpenCV 3.

x release series, with tons of improvements and bug fixes. Big thanks to everyone who particpated! If you contributed something but your name is missing, please, let us know. This is the first stabilization update in 3. x series. It shall be reminded that since OpenCV 3. Preliminary version of OpenCV HAL, low-level acceleration API beneath OpenCV, has been introduced. Currently it includes just a few math functions, but will grow soon.

For example,. Using such intrinsics one can write accelerated code, debug it on desktop and then run it without any changes on ARM and get reasonable performance. This is brief version of the change log. Also, big thanks to all the Itseez guys who reviewed patches, watched bug reports and helped OpenCV in many other ways: Alexander Shishkov who also maintains opencv.

x , you will need to update your code. To lower the footprint, highgui module has been split into 3 parts: imgcodecs, videoio and highgui itself thanks to Vladimir. You may need to update your code. We will fix it by OpenCV 3. New VTK-based 3D visualization module viz stabilized and back-ported to 2. The module provides a very convenient way to display and position clouds, meshes, cameras and trajectories, and simple widgets cube, line, circle, etc.

Full demo video can be found at Itseez Youtube channel. As usual, we created 2. You can check this branch for changes periodically, before as well as after 2. At the age of 12, OpenCV got its own home! org will be the official OpenCV user site. Some of the old functionality from the modules imgproc , video , calib3d , features2d , objdetect has been moved to legacy.

This is the fourth patch release in the 1. z series of runc, primarily fixing a regression introduced in 1. It also fixes a few other bugs. The runc binary distributed with this release are statically linked with the following GNU LGPL The versions of these libraries were not modified from their upstream versions, but in order to comply with the LGPL However we strongly suggest that you make use of your distribution's packages or download them from the authoritative upstream sources, especially since these libraries are related to the security of your containers.

This is the third release of the 1. z series of runc, and contains various minor improvements and bugfixes. This is the second patch release of the runc 1. It fixes CVE , a minor security issue which appears to not be exploitable related to process capabilities. This is a similar bug to the ones found and fixed in Docker and containerd recently CVE This release only contains very minor changes from v1.

y release series of runc. We do not plan to make any new releases of the 1. y release series of runc, so users are strongly encouraged to update to 1.

This release is the first release candidate for the next minor release following runc 1. It contains all of the bugfixes included in runc 1. A fair few new features have been added, and several features have been deprecated with plans for removal in runc 1. At the moment we only plan to do a single release candidate for runc 1. z runc branch. This is the third stable release in the 1. This release is expected to be the last point release in the 1. A potential vulnerability was discovered in runc related to an internal usage of netlink , however upon further investigation we discovered that while this bug was exploitable on the master branch of runc, no released version of runc could be exploited using this bug.

The exploit required being able to create a netlink attribute with a length that would overflow a uint16 but this was not possible in any released version of runc. For more information, see GHSA-v95c-p5hm-xq8f and CVE Due to an abundance of caution we decided to do an emergency release with this fix, but to reiterate we do not believe this vulnerability was possible to exploit. Thanks to Felix Wilhelm from Google Project Zero for discovering and reporting this vulnerability so quickly.

This is the second stable release in the 1. This is the first stable release in the 1. This release has quite a few last-minute bug-fixes and various correctness and performance improvements almost all of which are related to cgroup handling , and is the first non-rc release of runc in 5 years v1. It's been a very long road, and we thank the many contributors and maintainers that helped us get to this point approximately people in total.

As runc follows Semantic Versioning, we will endeavor to not make any breaking changes without bumping the major version number of runc. However, it should be noted that Go API usage of runc's internal implementation libcontainer is not covered by this policy -- for historical reasons, this code was not moved into an "internal" package this feature did not exist in Go at the time and because certain projects currently depend on this, we have not yet moved this code into an internal package.

Despite this, we reserve the right to make breaking changes in our Go APIs though we will note such changes in our changelog, and will try to avoid needless disruption if possible. Skip to content.

HugePageSizes which is more efficient. GetIntelRdtPath has been removed. Users who were using this function to get the intelrdt root should use the new intelrdt. Root instead. This may help in distinguishing between runc exec failures such as invalid options, non-running container or non-existent binary etc. and failures of the command being executed. This might be useful to check the state e.

of cgroup controllers after the container has exited. This allows users to create sophisticated seccomp filters where syscalls can be efficiently emulated by privileged processes on the host. Static builds for said architectures will be available for all future releases. Note that this does not permit the container any additional access to the host filesystem, it simply allows containers to have bind-mounts configured for paths the user can access but have restrictive access control settings for other users.

These have the same names as the proposed mount 8 options -- just prepend r to the option name such as rro. This includes critical information such as supported mount flags, hook names, and so on. Note that the output of this command is subject to change and will not be considered stable until runc 1. Cgroup structure fields : Systemd whether to use systemd cgroup manager ; and Rootless whether to use rootless cgroups. This allows to use any cgroup manager method e.
