(You can use the [Clear All] button to clear all the images and histograms)
1. Select an image by double clicking the image name in the image files list.
2. Change the window parameters with the required 3x3 matrix values - use Sobel or Prewitt masks
3. Change the values of Threshold, G1 or G2 as desired. Their values must be integers between 0 -255
4. Click on the desired buttons [Ga(x,y)], [Gb(x,y)] or [Gc(x,y)] to obtain processed image.
if G[f(x,y)]>=T,
- Ga(x,y)=G1 else Ga(x,y)=f(x,y)
- Gb(x,y)=G[f(x,y)] else Gb(x,y)=G2
- Gc(x,y)=G1 else Gc(x,y)=G2
