To obtain depth-from-stereo imagery, it is traditionally required that the baseline separation between images (or the base-to-height ratio) be very large in order to ensure the largest image disparity range for effective measurement. Typically, a B/H ratio in the range of 0.6-1 is preferred. As a consequence, most existing stereo-matching algorithms are designed to measure disparities reliably with...
Image denoising is one of important steps in a number of image processing applications. However, available methods mainly present by conducting filter of restoration on whole observation image, resulting in many image detail information have been lost. So, how to obtain the balance of remove noises from the smooth regions and preserved more image detail at high frequency regions have still worth to...
This paper presents a novel blind video watermarking method based on image complexion analysis. The image complexion information is extracted from the DC coefficient in sub blocks transformed by discrete cosine transform (DCT) to make sure the macroblock of image adapt to be embedded watermark information. Subsequently, the algorithm presents DCT coefficients space layered mode (DCSLM), and embeds...
