v.sameness single stream: output the similarity between a stream and comparison values dual stream: output the similarity between pixels in two streams single stream: output the similarity between a stream and comparison values dual stream: output the similarity between pixels in two streams In single stream mode, v.sameness outputs the degree of similarity between each pixel’s components and the comparison values. It will output a maximum value of 255 when the pixel's components are exactly the same as the comparison value. As the pixel values get farther from the comparison value, the output levels decrease. Higher sensitivity levels result in less tolerance to difference. Each component of the stream is processed and output separately. U and V component outputs will range between 0 and 127. Dual stream mode operates in the same way but the comparison is between corresponding pixels in stream 1 and 2. The comparison values are ignored. In single stream mode, the incoming stream will be forced to 8-bit components before processing unless the incoming stream is a flo
