摘要
The problem of image enhancement for low-contrast medical images with complex structure was considered. The histogram-based method for automatic contrast enhancement of low-contrast images with small-size objects on the basis of the analyzing of contrast distribution at boundaries of objects and background was proposed. The proposed method is intended for automatic preprocessing of complex medical images with small-size low-contrast objects (with the details) in image. The research of the effectiveness for the proposed and the well-known histogram-based methods of automatic contrast enhancement were conducted using the known no-reference contrast metrics.
