We proposed a method to fabricate large area uniform microlens array with a wide range of focal length for integral imaging. A thin hydrophilic layer with matrix array of circular holes was first fabricated on flat substrate by photolithography. A hydrophobic layer was then imprinted on top of the hydrophilic layer. By filling a very low viscosity prepolymer material into each circular hole via drop-on-demand...
The just noticeable difference (JND) in black level (BL), white level (WL), and chroma as visible in natural images under practical viewing conditions is determined. The same experiments are conducted in China and in the Netherlands to evaluate possible ethnic differences in the size of JNDs. In both countries, there is a strong effect of image content on the JND of BL and WL, while for most images...
Motion blurring on liquid crystal display (LCD) was modeled by the original image convoluted with a point spread function (PSF). An intensity independent PSF was first deduced by statistical approximation. Based on the PSF, a motion adaptive deblurring filter was proposed to restore the original image. The simulation of motion blurred and deblurred natural images were presented. The results indicate...
