In this case gradient percolation may be used as a filter for recovering fuzzy images. This filter has the advantage of self-adjusting and to be neutral in regard to the size of the objects. In particular it could be used to increase artificially the depth of focus on photographs that are...

we need the value of the previous output elements in the sequence. This contrasts with a finite impulse response filter – where the output depends only on the inputs, has no output dependence, and we can efficiently process them in parallel....

답변:Image Analyst2018년 12월 9일 I have applied a prewitt filter to an image with the following kernel [-1 -1 -1;0 0 0;1 1 1]. I would like to use the output as a way of calculating the image gradient. THis is done by calculating (z7+...

These filter masks are commonly known as the Sobel operator. Notice that the factors 18 in (1.25) simply represent a scaling, and they are usually omitted. By selecting different weights w(·, ·) in (1.22), other well-known gradient operators for edge detection are derived, such as the ...
