Blur, which will use OpenCV's blur image processing function. The component implements private methods that get a pointer to the underlying image data buffer which can be used directly by the OpenCV library, making it simple to extend the helper component to implement other OpenCV processing ...
1D mat support in OpenCV DNN is going on the new hash TSDF implementation has been integrated; better performance and memory footprint GSoC: webasm was integrated; bit-exact version of SIFT is still in progress. Shiqi: network for CI is ready in Shenzhen; can be accessed worldwide. ARM...
