Amplify differences between current pixel and pixels of adjacent frames in same pixel location.
This filter accepts the following options:
- radius
-
Set frame radius. Default is 2. Allowed range is from 1 to 63. For example radius of 3 will instruct filter to calculate average of 7 frames.
- factor
-
Set factor to amplify difference. Default is 2. Allowed range is from 0 to 65535.
- threshold
-
Set threshold for difference amplification. Any difference greater or equal to this value will not alter source pixel. Default is 10. Allowed range is from 0 to 65535.
- tolerance
-
Set tolerance for difference amplification. Any difference lower to this value will not alter source pixel. Default is 0. Allowed range is from 0 to 65535.
- low
-
Set lower limit for changing source pixel. Default is 65535. Allowed range is from 0 to 65535. This option controls maximum possible value that will decrease source pixel value.
- high
-
Set high limit for changing source pixel. Default is 65535. Allowed range is from 0 to 65535. This option controls maximum possible value that will increase source pixel value.
- planes
-
Set which planes to filter. Default is all. Allowed range is from 0 to 15.
