interesting Computer vision projects
color-based face detection
traditional segmentation: thresholding + connected component
card detector and warp perspective
texture and feature extraction: window sliding + raw feature segmentation
for higher segmentation resolution, you may try using lower window_size ( the below image was applied with only (20x20) )
simple object recognition
pyramid mean shift filtering, connected component algorithm, WaterShed algorithm, Hough, Circle Transform, IOU_thresholding
