| Description |
Function imDecompNTSC takes one input argument, an M x N x 3 array representing a full-color RGB image, and displays four images: the original full-color image, and the three NTSC component images, or YIQ. These components include the luminance Y, the in-phase chrominance I, and the quadrature chrominance Q. The chrominance images are displayed using appropriate colormaps: SkyBlue-Orange for the in-phase, and Green-Magenta for the quadrature phase. The function returns a handle to the figure window.
