Transformation Consistency Regularization - A Semi Supervised Paradigm for Image to Image Translation

We can train image-to-image networks in a semi-supervised manner with 50% or less of paired data, or we can improve performance using using large quantities of unpaired data. The method works with multiple tasks, including single-image super-resolution, denoising, semantic segmentation, colourization and others.

A perceptual model of motion quality for rendering with adaptive refresh-rate and resolution

Is it better to render at 4K or 144Hz? The quality of motion depends on the velocity, the type of eye motion, viewing distance and other factors. We model the influence of all those factors on the perceived quality of motion and use such a model to adaptively select refresh-rate and resolution for rendering.

Spatio-chromatic conteast sensitivity function for high dynamic range

A luminance and colour contrast sensitivity function has been measured and modelled in the range of luminance from 0.001 cd/m^2 to 10,000 cd/m^2. The new function can predict detection thresholds for three colour directions, a range of frequencies, luminance levels and stimulus sizes.
