75‐2: The Effect of Chromatic Aberration Correction on Visually Lossless Compression

In augmented and virtual reality (AR/VR), magnifying display lenses typically introduce pincushion distortion and transverse chromatic aberration. These distortions are corrected by pre‐processing, one side‐effect of which is disruption of the spatial correlation between color channels. As a result, the standard practice of performing color space conversion prior to image compression may introduce undesirable, visible artefacts. To assess this, we evaluated the performance of two low impairment display stream codecs on distortion corrected stereoscopic images based on converting to YCoCg color space or bypassing the color conversion.
