    CONVERT IMAGE INTO YIQ MODEL (REPRESENT IN-PHASE VALUE)
    Final YIQ model without the quadrature value Q = 0
    
    In YIQ the Y component represents the luma information, 
    I and Q represent the chrominance information. 
    I stands for in-phase, while Q stands for quadrature, referring to the components 
    used in quadrature amplitude modulation.
