An Automatic Method for Image Matting Based on Saliency Detection ⋆

Image matting aims at extracting foreground from a given image by means of color and alpha estimation. An automatic matting method based on saliency detection was proposed in this paper, which takes the advantages of saliency detection as prior information instead of user interaction. After getting the saliency map, a cost function was constructed to obtain an alpha matte. Moreover, with the in...

An Automatic Ship Detection Method Based on Local Gray-Level Gathering Characteristics in SAR Imagery

This paper proposes an automatic ship detection method based on gray-level gathering characteristics of synthetic aperture radar (SAR) imagery. The method does not require any prior knowledge about ships and background observation. It uses a novel local gray-level gathering degree (LGGD) to characterize the spatial intensity distribution of SAR image, and then an adaptive-like LGGD thresholding...
