基于Curve Let变换的X射线图像增强算法

Study of the X-Ray Image Enhancement Algorithm Based on Curve Let Transform

为了提高了X射线图像的对比度和细节显示的清晰度,应用基于Curve let变换的图像增强算法,对原图像进行增强。试验结果表明,该算法与直方图均衡化、同态滤波等算法相比,有效地增强了对比度、抑制了背景噪声。相比之下,Curve let变换更具有优势。

In order to improve the contrast and clarity of details of the radiographic images,the image enhancement algorithm based on Curve Let transform was applied to deal with the original images.The experimental results showed that this algorithm could effectively enhance contrast and control the background noise compared with other algorithms,such as homomorphism filter and histogram equalize.In contrast,Curve Let transform had more advantages.
