Video matting is defined as the process of changing the background of the video by extracting the foreground image from each frame of a video. In this paper, we propose a video matting technique which uses Ncut segmentation technique to segment the frames. Further, Sobel edge detection technique is used on the segmented frames for detecting edges. Afterwards, Edge thickening process fills up all the...
Gallstones are solid particles formed from bile in the gall bladder. In this paper, we propose a technique to automatically detect gallstones in ultrasound images, christened as, automated gallstone segmentation (AGS) technique. Speckle noise in the ultrasound image is first suppressed using anisotropic diffusion technique. The edges are then enhanced using unsharp filtering. NCUT segmentation technique...
