In this paper, we present a global contrast intensification approach. Contrast intensification is generally carried out as a contrast expansion and after that a tonal intensification is followed. In this paper, we present a new contrast intensification method. First of all, a color image in RGB color space is transformed into YIQ color space. Then, the Y channel of YIQ is contrast restricted. We apply proposed histogram equalization approach on Y channel, or separated each channel of Y, I, and Q channels. The experimental results prove that the processed images look good-natured.
