Abstract

This paper addresses the low contrast problem of medical images. The low contrast medical images are unable to process for effective diagnosis. This problem can be overcome with this proposed novel histogram based image enhancement technique. The enhancement process starts with computing histogram values of an image. These histogram values are further used to remap the low contrast image intensity values with enhanced pixel values. The resultant enhanced image is compared with standard (basic) enhancement techniques to check the high visual clarity of the proposed algorithm.

利用直方图均衡化增强医学图像的诊断性观察
本文解决了医学图像对比度低的问题。低对比度的医学图像无法进行有效的诊断。本文提出的基于直方图的图像增强技术可以克服这一问题。增强过程从计算图像的直方图值开始。这些直方图值进一步用于将低对比度图像强度值重新映射为增强的像素值。将得到的增强图像与标准(基本)增强技术进行比较,以检查所提出算法的高视觉清晰度。
