Precision can be increased by using 64bit floating point (per component)ĮDIT: Above 圜MS_x86 (home site is now dead) and thread here on D9 not active since 2013.Īpply two 3x3 matrices to each pixel? :. Since all the computing is performed offline its Performed at runtime using lower computational power and leaving more CPUĪvailable for other tasks. Mapping the input data through the 3D LUTs. Which can later be used, when playing videos or viewing photos, simply by TheĬomputed 3D LUTs (three, one for each component) are then written to a file Using 3D LUTs all computing is performed offline during its creation. The idea of using 3D LUTs was due to the intensive computing that needs toīe performed when converting video data between different color spaces. You can read a little more about CMS here: Tables ("3D LUTs") to perform the conversion between the input and outputĬolor representations. YCMS is a Color Management System (CMS) that uses 3-dimensional lookup YCMS_x86, excerpt from manual, (maybe there is an 圆4 version somewhere) I have no idea if these couple of files are of any interest to anyone (had them for years, never really looked at them much).
