WebIf MaskWidth or MaskHeight is even, the next larger odd value is used. Altogether, a value of 3 can be considered the minimum sensible value.. StdDevScale. The local standard deviation is used as a measure of noise in the image. It can be scaled by StdDevScale to reflect the desired sensitivity. A higher value means that only pixels that are very different … WebThe operator fill_interlace calculates an interpolated full image or removes odd/even lines from a video image composed of two half images. If an image is recorded with a video camera it consists of two half images recorded at different times but stored in one image in the digital form. This can lead to several errors in further processing.
