Cvtool is based on CVL and does all of the processing on the graphics processing unit (GPU), which is much faster than the CPU for many tasks, especially when processing large images or videos.
Full floating point precision is supported both in storage and in processing. Cvtool can perform transformations, color manipulations, blending, filtering and much more both with conventional image files and with arbitrary floating point data, including high dynamic range (HDR) images.
