A saliency-based target detection method for forward looking infrared (FLIR) image is proposed. Firstly, saliency map is computed using scale-space representation and separated into dark saliency map (DSM) and bright saliency map (BSM). Secondly, dark and bright regions of interest (ROI) are detected by respective type of saliency map using marker-based maximally stable extremal regions (MSER) detection...
Multi-focus fusion is an important technique to integrate focal information from a set of input registered images. In this effort, a novel image fusion algorithm based on multi-scheme is presented. Given an over-complete Gabor dictionary, through matching pursuit signal decomposition algorithm, each source image can be described by sparse combinations of these atoms. Then the coefficients of the fused...
Recent studies have found that adoption of structural similarity index (SSIM) was successful in reflecting human visual characteristics better compared with traditional peak signal-to-noise ratio (PSNR) metrics. However, this method shows some weaknesses when evaluating the quality of blurred images and noise images. Good quality results were hardly achieved as they do not match the human visual system(HVS)...
