Abstract
This paper presents the results of using self quotient image (SQI) to flatten the background region of a thin film transistor liquid crystal display image. To overcome an inherent shortcoming of SQI method, namely the halo effect in thin film transistor liquid crystal display images, double SQI method is introduced. Experimental results demonstrate that SQI can be used effectively to eliminate a non-uniformity of the background region in a test image.
