Pedestrian detection using HOG with a linear SVM and non-maximal suppression. Uses nanovg for rendering (OpenGL), detects using a linear SVM (OpenCV/OpenCL), filters resuls using NMS (CPU). Decodes/encodes on the GPU (VAAPI).
Note: Detection rate is not very impressive and depends highly on the video.
Face beautification using face landmark detection (OpenCV/OpenCL), nanovg (OpenGL) for drawing masks and multi-band (OpenCV/OpenCL) blending to put it all together. Note: There are sometimes little glitches because face landmark detection is not very accurate and has rather few points.
