Abstract: |
In this paper, we study compensation of defective subpixels with insufficient maximum brightness. The aim of the compensation is to minimize the perceived image non-uniformity. Compensation of the displayed image non-uniformity is based on minimizing the perceived distance between the target (ideally displayed) and the simulated image displayed by the calibrated screen. In this work, we compare the efficiency of compensation depending on color coordinates we calculate color difference in. We investigated the behavior of compensations based on two different uniform color coordinates: CIELAB and Oklab. We examine the efficiency of the compensation on natural scenery images. It was found that Oklab shows better performance than CIELAB in terms of uniformity of perceived compensated image. However, taking into account the spatial properties of the human visual system using S-CIELAB preprocessing almost eliminates the difference between the color coordinates. |
