Abstract

An adaptive non-uniform illumination panoramic image enhancement algorithm was proposed, which can improve the visual effect of panoramic images captured under non-uniform illumination. Firstly, according to the illuminance-reflection imaging model, we adopt a bilateral filtering method to decompose the brightness into illuminance component and reflection component. Secondly, an adaptive gamma correction function is constructed, which can dynamically adjust the illuminance component. In the reflection component processing, an improved morphological operation is proposed to denoise and enhance the image details. Finally, we combine the illumination component with the reflection component to get the enhanced panoramic image. The experimental results show that the proposed algorithm can improve the effect of non-uniform illumination on the panoramic image, and can obtain better image contrast, detail information and visual effect.
