基于自适应阈值的不规则光照下图像提取方法

Image Extraction in Irregular Light Based on Self-adaptive Threshold Value

目标图像提取是进行图像处理的主要目的。研究发现,在图像拍摄中,光照条件是主要影响因素。不均匀光照下拍摄的图像会产生高光区、阴影区或不规则的边缘,从而影响图片的质量和信息的读取。针对上述问题,提出了一种自适应的阈值分割方法,该方法能快捷的分割前景和背景,提取出目标信息。

The extraction of the target image is often the main purpose of image processing that lighting conditions is one of the major influencing factors in image shooting. The captured Studies have shown image will have high light areas, shaded areas, or irregular edge in uneven illumination that will affect the quality of the pictures and reading information. In view of these issues, this paper proposes an extraction method based on self-adaptive threshold value. This method can split the foreground and background quickly in order to extract the target information.
