Image saliency detection counts much in image processing and computer vision. Basic features like color, texture and contrast, have been adopted in the construction of saliency map. However, given a complex image, high-level features should be taken into consideration. In general, among the objects with different spatial location, humans tend to focus more on the front-most one. Hence in this paper,...
We demonstrate a multi-electrode Fresnel-type 2-D/3-D switchable display with electrically controlled birefringence mode liquid crystal (LC) lenses. By applying a discontinuous nonuniform electric field, the display with this structure can form a Fresnel-type refractive-index distribution to generate 3-D images. Compared to a normal LC lens, the Fresnel-type LC lens can achieve faster switching speed...
