ROLE OF OPTICS IN DEPTH ACCURACY A. Spatial Domain Analysis An image i x captured by an image sensor is formed from a sharp preimage s x, blurred by the optics, the defocus, http://www.ee.sunysb.edu/~cvl/publications.html WebMay 31, 2016 · Abstract: Depth from defocus based methods rely on measuring the depth dependent blur at each pixel of the image. A core component in the defocus blur estimation process is the depth variant blur kernel. This blur kernel is often approximated as a Gaussian or pillbox kernel which only works well for small amount of blur. peoples choice york sc
