As smartphones equips with low frame rate cameras and lower processing speed, I'm searching for high speed real-time object detection technique using this camera. It'll be appreciated for any related answers. Thanks in advance...
Sobel edge detector is very fast! Otherwise, you can try Prewitt and Roberts edge detectors. The Laplacian filter is good too. The Canny edge detector are not recommended for real-time video.
You can try plugin YouTube Video Effects for Chrome: https://chrome.google.com/webstore/detail/jdjldbengpgdcfkljfdmakdgmfpneldd. It has serveral filter that apply in real-time video for YouTube, including high quality, but it is still smooth.
