【摘要】 图像增强是“数字图像处理”课程的一项重要教学内容。针对图像增强方法的实践训练，给出一个综合实验-非均匀光照图像双分量增强Retinex算法，该实验整合了灰度变换、直方图均衡、图像平滑、去锐化掩模、高频增强等图像增强方法，并引入用于图像质量评价的量化指标等内容，图像增强效果好，对于图像增强的实践教学具有较好的参考价值。更多还原

【Abstract】 Image enhancement is an important content in the course of Digital Image Processing. Focusing on practical training of image enhancement techniques, a comprehensive experiment—two components enhanced retinex algorithm for uneven lighting images is presented. The experiment integrates image enhancement techniques such as histogram stretching, histogram equalization, image smoothing, unsharp masking, high-boost filtering, and introduces quantitative indexes for image quality assessment. It brings improved image quality and provides a valuable reference to the practical teaching of image enhancement.更多还原
