Prewitt/Sobel¶
- std.Prewitt(clip clip[, int[] planes=[0, 1, 2], float scale=1])¶
Creates an edge mask using the Prewitt operator.
- std.Sobel(clip clip[, int[] planes=[0, 1, 2], float scale=1])¶
Creates an edge mask using the Sobel operator.
- clip
Clip to process. It must have integer sample type and bit depth between 8 and 16, or float sample type and bit depth of 32. If there are any frames with other formats, an error will be returned.
- planes
Specifies which planes will be processed. Any unprocessed planes will be simply copied.
- scale
Multiply all pixels by scale before outputting. This can be used to increase or decrease the intensity of edges in the output.
