远程医疗图像增强技术在DM6437上的应用

为了解决远程医疗系统中图片本身以及传输产生的图像模糊化、对比度降低、动态范围大等问题。提出了一种基于DM6437和改进型的Retinex算法的远程医学图片增强方法,本文在全局Retinex算法的基础上利用自适应的线性拉伸方法增强图像,并将算法优化后移植到DM6437平台,实现了在嵌入式平台的应用。结果表明:本系统既可实现低对比的远程医学图像增强,又能实现图像的动态范围压缩,可显著提高暗区图像的信息,克服了常规图像增强算法的不足,可以满足远程医疗的要求。

The Application of Telemedical Image Enhancement Technology on DM6437

In telemedical system,there exist image problems caused by images themselves or during transmission,such as bluring,contrast reduction,big dynamic range.In order to solve these problems,a method for telemedical image enhancement is proposed in this paper.It's based on DM6437 and improved Retinex algorithm.This paper employs adaptive linear stretching method on the basis of the Global Retinex algorithm to enhance the contrast of the image.The algorithm is optimized later and then transplanted to DM6437 platf...
