摘要: 利用直方图均衡、中值滤波和小波变换对CT图像(512×512)增强处理的方法进行了研究,实验结果表明,小波变换增强方法可以减少噪声的放大,在增强图像微小细节和避免放大噪声两方面获得令人满意的结果,其处理结果优于直方图均衡和中值滤波的增强方法。

Abstract: The enhancement methods for CT Image were studied by means of the histogram equalization,median filtering and the wavelet transform..Experiment results indicate that the wavelet enhancement in this paper can reduce the amplification of noise and achieve an excellent balance between the enhancement of subtle image detail and the avoidance of noise amplification.The method was preceded with that of the histogram equalization and the median filtering.
