amplify

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.
