Abstract:

 The previous backlight image detection algorithms such as intensity histogram-based method and the YCrCb histogram-based method are low in accuracy rate. A backlight image detection algorithm based on details is presented. The change of the number of details under various Gamma correction is analyzed for the determination of backlight images. The experimental results show that the proposed method outperforms the intensity histogram-based method and the YCrCb histogram-based method.
