Deflate/Inflate¶
- std.Deflate(vnode clip[, int[] planes=[0, 1, 2], float threshold])¶
Replaces each pixel with the average of the eight pixels in its 3x3 neighbourhood, but only if that average is less than the center pixel.
- 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.
- threshold
Allows to limit how much pixels are changed. Output pixels will not become less than
input - threshold
. The default is no limit.
- std.Inflate(vnode clip[, int[] planes=[0, 1, 2], int threshold=65535])¶
Replaces each pixel with the average of the eight pixels in its 3x3 neighbourhood, but only if that average is greater than the center pixel.
- 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.
- threshold
Allows to limit how much pixels are changed. Output pixels will not become greater than
input + threshold
. The default is no limit.
