NAME

blur_2x2/contrast_enhance_2x2/edge_detect_2x2 - Use a fast 2x2 kernel to detect edges/enhance/smooth image

SYNOPSIS

  <Image>/Filters/Edge-Detect/2x2 Edge Detect
  <Image>/Filters/Blur/2x2 Blur
  <Image>/Filters/Enhance/2x2 Contrast Enhance

DESCRIPTION

Detect edges in the image using a 2x2 kernel. It is similar to Sobel, yet sharper (and lower quality).

Implements some algorithms described in (the otherwise very bad) http://www.biocomputer.com/Thesis.html

These are all simple 2x2 kernels, fast but relatively effective.

PARAMETERS

 # none
