- Update to 4.3.0
* DNN module:
+ Improved layers / activations / supported more models:
- ONNX: LSTM, Broadcasting, Algebra over constants, Slice with
multiple inputs
- DarkNet: grouped convolutions, sigmoid, swish, scale_channels
- MobileNet-SSD v3: #16760
+ New samples / demos:
- Clothes parts segmentation and CP-VTON
- DaSiamRPN tracker
Intel® Inference Engine backend (OpenVINO™):
- added support for custom layers through nGraph OpenVINO
API: #16628
- nGraph OpenVINO API is used by default: #16746
+ Many fixes and optimizations in CUDA backend (thanks to
@YashasSamaga)
+ OPEN AI LAB team submitted the patch that accelerates OpenCV
DNN on ARM using their Tengine library
* G-API module:
+ Introduced a new graph-level data type GOpaque<T>. This type
can be used to pass arbitrary user data types between G-API
nodes in the graph (supported for CPU/OpenCV backend only).
+ Introduced a way to declare G-API CPU (OpenCV) kernels in-place
+ Added a new sample "Privacy masking camera", combining Deep
Learning with traditional Image Processing (link)
+ Added more operations in the default library: WarpAffine,
WarpPerspective, NV12toGray.
* Performance improvements:
+ IPP-ICV library with CPU optimizations has been updated to
version 2020.0.0 Gold
+ SIMD intrinsics: integral, resize, (opencv_contrib) RLOF
implementation #2476
* And many other great contributions from OpenCV community:
+ (opencv_contrib) Computer Vision based Alpha Matting
(GSoC 2019) #2306
+ calib3d: findChessboardCornersSB improvements: #16625
+ calib3d: updated documentation for RT matrices: #16860
+ core: improved getNumberOfCPUs(): #16268
+ imgproc: new algorithm HOUGH_GRADIENT_ALT is added to
HoughCircles() function #16561. It has much better recall
and precision
+ imgcodecs: added initial support for OpenJPEG library
(version 2+): #16494
+ highgui(Qt): added Copy to clipboard: #16677
+ dnn: TensorFlow, Darknet and ONNX importers improvements
by @ashishkrshrivastava
+ (opencv_contrib) added rapid module for silhouette based 3D
object tracking: #2356
+ (opencv_contrib) SIFT detector is enabled by default due
patents expiration (without requirement of NONFREE build
option)
+ help materials: OpenCV Cheat Sheet in Python: #4875
* Changes that can potentially break compatibility:
+ image filtering functions throws exception on empty input
(voting results)
- Packaging changes:
* Stop mangling CMake diagnostic output, no dependency versions
end up in the packages anyway, drop opencv-build-compare.patch
* Set empty OPENCV_DOWNLOAD_TRIES_LIST, skip downloads even when
network is available during builds (e.g. local build).
* Drop upstream GLES patches:
+ 0001-Do-not-include-glx.h-when-using-GLES.patch
+ opencv-gles.patch
