—The rapid progress of the multimedia signal processing has contributed to the extensive use of multimedia devices with small liquid crystal display (LCD) panel. With the proliferation of mobile devices with a small display, the video sequences captured for normal viewing on standard TV or HDTV may give the small-display viewers uncomfortable experience in(More)
In this paper, we propose a novel and fast algorithm that can detect defects on images with repeated patterns. This task is done through saliency detection by using spectral residual, which is based on Fourier Transform. In detail, the difference between the original signal and a smooth one in the log amplitude spectrum is calculated, and the saliency map(More)
