Saliency detection is a technique for automatically extracting regions of interest from the background and has been widely used in computer vision field. This study proposes simple effective saliency method combining color contrast hash fingerprint. In our solution, input image segmented into nonoverlapping superpixels, so as to perform at region level reduce computational complexity. A optimiz...

To perform a more complete diagnosis on the effect of color vision deficiency on visual performance we measured luminance and color contrast threshold functions. Measurements were carried out on CRT for a range of spatial frequencies on color deficient and normal color vision individuals. Luminance and color contrast threshold is a measure of the recognition limits of low luminance and color co...
