Convert a RGB image to the equivalent NTSC image YIQ.
YIQ = rgb2ntsc(RGB)
A RGB image (hypermat), the dimension of RGB should be M x N x 3 .
Output image, which has the same size as RGB and type of double.
rgb2ntsc convert a RGB image to the equivalent NTSC image YIQ using:
Y = 0.299*R + 0.587*G + 0.114*B
I = 0.596*R - 0.274*G - 0.322*B
Q = 0.212*R - 0.523*G - 0.311*B
Supported classes: INT8, UINT8, INT16, UINT16, INT32, DOUBLE. If RGB is not a double image, it will be converted to double image first in the procedure.
RGB = imread(fullpath(getIPCVpath() + "/images/baboon.png")); YIQ = rgb2ntsc(RGB); RGB = ntsc2rgb(YIQ); imshow(RGB); | ![]() | ![]() |
