integralFilter
Filter using integral image
Description

Tips
The filter size does not affect the speed of the filtering operation. Thus, the
integralFilter
function is ideally suited to use for fast analysis of images at different scales, as demonstrated by the Viola-Jones algorithm [1].The
integralFilter
function uses correlation for filtering. Therefore, the filter is not rotated before calculating the result.
