  We present a versatile computational image rendering software of
optically-acquired holograms. The reported software can process 4 Megapixel
8-bit raw frames from a sensor array acquired at a sustained rate of 80 Hz.
Video-rate image rendering is achieved by streamline image processing with
commodity computer graphics hardware. For time-averaged holograms acquired in
off-axis optical configuration with a frequency-shifted reference beam,
wide-field imaging of one tunable spectral component is permitted. This
software is validated by phase-stepped hologram rendering, and non-contact
monitoring of surface acoustic waves by single and dual sideband hologram
rendering. It demonstrates the suitability of holography for video-rate
computational laser Doppler imaging in heterodyne optical configuration.
