In this algorithm is transforming color image from basic RGB color space to YIQ color space, the forward transform is given by equation [12]:
As the commonly used RGB color model creates color distortion due to the high correlation among the R, G, and B components, we transform it into YIQ color model.
One of the possible solutions which may be applied for increase of the possibility of proper recognition of the QR code may be conversion of the image from RGB colour model into some other popular colour spaces such as CIE XYZ, CIE LAB, HSV, YIQ or YCbCr.
In a color image, RGB is one of mostly used color spaces, but in this study, it is constructed into some other special color spaces for special applications, as well known, the HIS model is used in the color enhancement applications and the YIQ model is in the NTSC color television.

In [4], color image to be sharpened is first converted to YIQ or CIELAB color space, and then the method of unsharp masking and fuzzy morphological sharpening will be used to adjust the intensity of pixels around boundaries [4].

In [8], a new hybrid color space combining the RGB and YIQ color spaces was proposed.
