v.min single stream: pass along the minimum of the pixel level and the int dual stream: pass along the darkest pixel components between two streams single stream: pass along the minimum of the pixel level and the int dual stream: pass along the darkest pixel components between two streams In single stream mode, each output pixel of v.min uses the lesser of the input brightness and the integer value. The image is forced to int8 components in all formats. In dual stream mode, each output pixel is made up of the smallest corresponding components of the pixels of the two streams. In dual stream mode, both streams will be forced to int8 components before processing. Also, the second stream will be forced to the same format (rgb, yuv or grays) as the first stream. N.B. v.min has a slightly different behaviour in yuv mode since the magnitudes of u and v components are not brightness related. Only the y component is affected in this case.
