“…Like RGB, the YIQ color space is a device-dependent color space which means the actual color you see on your monitor depends on what kind of monitor you are using and what its settings are [44]. In the NTSC format, image data consists of three components: luminance (Y), hue (I), and saturation (Q).…”

“…In this color space, Y-component stands for luminance or brightness, the I-component seems to mimic mostly shifts from blue, through purple to red colors (with increasing I), and the Q-component seems to mimic mostly the value of green; the I and Q components jointly represent the chromatic attributes [44].…”

“…This color space exploits certain characteristics of human-eye color response and improves the appearance of the color image in terms of human brightness perception. In this technique, the contrast enhancement using fuzzy intensification operator was applied only on luminance component; hence color information of the original image is preserved [17].…”

“…The transform from RGB to YIQ and the backward transform from YIQ to RGB are as follow [7 and 8]: where Y-component stands for luminance or brightness, the I-component seems to mimic mostly shifts from blue, through purple, to red colors (with increasing I), and the Q-component seems to mimic mostly the value of green; the I and Q components jointly represent the chromatic attributes [8]. The decorrelation of R, G, and B component images makes the Y, I and Q component images complementary to each other [8]. For RGB values with a range of 0-255, Y has a range of 0-255, I a range of 0 to ±152, and Q has a range of 0 to ±134.…”
