WebN. -D inverse discrete cosine transform. Y = IDCTN (X) returns the inverse discrete cosine transform (IDCT) of X. The array Y is the same size as X and contains the inverse discrete cosine transform coefficients. This transform can be inverted using DCTN. IDCTN (X,DIM) applies the IDCT operation across the dimension DIM. WebJul 13, 2016 · The problem with the "jet" color mapping is that the highest point in the mapping (corresponding to larger values) is given a red color, the middle range is given a yellow-green color, and the lowest is blue--but if we look at the perceived "brightness" (i.e., luminance) of those colors, it is clear that this mapping is not monotone.
