摘要
超声图像增强处理一直是图像处理中的研究热点,针对当前图像增强算法去噪效果差、清晰度不够等缺陷,提出一种基于多尺度Retinex的超声图像去噪及增强技术。首先采用曲波变换对超声图像进行去噪处理,消除噪声对图像增强效果的不利影响,然后采用多尺度Retinex算法对超声图像进行增强处理,并通过双边滤波代替Retinex算法的高斯滤波,最后采用超声图像对其进行测试实验,结果表明,本文方法有效改善了超声图像的视觉效果,客观评价指标要明显优于当前常见的超声图像增强方法。
Ultrasonic image enhancement processing is a hot research topic in image processing, the traditional image enhancement algorithms have poor effect, and this paper proposed an ultrasonic image denoising and enhancement technology based on multi-scale Retinex. Firstly, the image is processed by curvelet transform, and the bad effect of noise is eliminated, and secondly the multi-scale Retinex algorithm is used to enhance the ultrasonic image, and the Gauss filter in Retinex algorithm is replaced by the bilateral filter, finally, the ultrasonic image is used to test the performance. The experimental results show that the proposed method can effectively improve the image visual effect and the evaluation index is better than the common ultrasonic image enhancement methods.
