摘要: Depth map estimation from Defocus is a computer vision technique which has wide applications such as constructing the $3D$ setup $2D$ image(s), image refocusing and reconstructing scenes. In this paper, we propose an application of to novel keyboard design for detecting keystrokes. The proposed can be integrated with devices mobile, PC tablets generated by either printing on plain paper or projection flat surface. utilizes measured defocus together precalibrated relation between amount pattern infer depth, which, along azimuth position stroke identifies key. As does not require any other hardware besides monocular camera, makes approach cost effective feasible solution portable keyboard.
