Image Comparison and Analysis Tool Now Available from NVIDIA (ICAT)

Analyzing the quality of video images is long and tedious. So we created an image comparison and analysis tool that we call ICAT, to make life easier for our testers and engineers.

Our teams have found the tool so useful that we have decided to make it available to everyone, making it much easier to perform accurate and fast image quality assessments between multiple images or videos.

NVIDIA ICAT allows users to easily compare up to 4 screenshots or videos with sliders, side-by-side and zoom in to see pixels. Align the comparisons spatially and temporally, examine the differences and draw your conclusions. To compare different scaling technologies, we encourage you to first use ICAT to find the most comparable image quality modes, and then examine the performance gains. Note that just because two quality modes have the same name does not mean that they are equivalent. Although it varies by game and resolution, we found DLSS Performance mode to be the best compared to the Ultra Quality mode of space upscalers. We call this approach “ISO Quality”, because the performance is compared to equivalent image quality levels. The NVIDIA ICAT program is now available for download at this link.
