v.< single stream: compare each pixel's brightness to an integer dual stream: compare corresponding pixels' brightness in two streams single stream: compare each pixel's brightness to an integer dual stream: compare corresponding pixels' brightness in two streams In single stream mode, v.< compares each pixel in the input stream to the int that was received in the right inlet. Where the brightness of the pixel is less than the test value, v.< outputs 255, otherwise it outputs 0. In dual stream mode, v.< compares each pixel in stream 1 with the corresponding pixel in stream 2. Where the stream 1's brightness is less than stream 2's, v.< outputs 255, otherwise it outputs 0. v.< compares only brightness.
