Image Halftoning Research at UT Austin
Video display on devices with limited bit-depth
capabilities requires conversion of the original (continuoustone)
video having a higher bit-depth to one having a lower
bit-depth. Video halftoning refers to a process that attempts
to perform this conversion such that the resulting halftone
video is perceptually similar to the continuous-tone video.
This quantization process, however, results in artifacts. A
video halftoning algorithm can be assessed by quantifying the
artifacts introduced by it. In this paper, we discuss an approach
to assess flicker, a typical temporal artifact, in low-to-medium
frame-rate binary video halftones produced from grayscale
