3. VIDEO COLOUR VARIATION DETECTION AND MOTION MAGNIFICATION TO OBSERVE SUBTLE CHANGES
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Our thesis work is based on revealing minor informative variations in a video which are hard to perceive, that can be further exaggerated to extract hidden variations of color and motions in a video. In our thesis we apply di erent techniques of a video decomposition like Laplacian, Steerable and Gaussian pyramids to observe the improvement in performance of the videos. READ MORE
