WebJ = deconvlucy(I,psf,iter,dampar,weight) specifies which pixels in the input image I are considered in the restoration. The value of an element in the weight array determines how much the pixel at the corresponding position in the input image is considered. For example, to exclude a pixel from consideration, assign it a value of 0 in the weight array.
