Member nameValueDescription
CV_DXT_FORWARD0 Do forward 1D or 2D transform. The result is not scaled
CV_DXT_INVERSE1 Do inverse 1D or 2D transform. The result is not scaled. CV_DXT_FORWARD and CV_DXT_INVERSE are mutually exclusive, of course
CV_DXT_SCALE2 Scale the result: divide it by the number of array elements. Usually, it is combined with CV_DXT_INVERSE, and one may use a shortcut
CV_DXT_ROWS4 Do forward or inverse transform of every individual row of the input matrix. This flag allows user to transform multiple vectors simultaneously and can be used to decrease the overhead (which is sometimes several times larger than the processing itself), to do 3D and higher-dimensional transforms etc
CV_DXT_INV_SCALE3 Inverse and scale
