摘要 针对医学图像数据量大、存储和传输对内存和带宽要求高的问题,提出一种基于双重压缩协议的医学图像压缩方法。首先,使用方形网络对图像进行缩小处理;然后,利用数字水印技术在缩小图像的每个像素中嵌入该像素最佳放大方法的编码;最后,对水印图像利用JPEG-LS无损压缩得到最终的压缩图像,并进行存储和传输。对磁共振(MR)图像和计算机断层(CT)图像两种医学图像进行实验,实验结果表明,与其他方法相比,所提方法具有明显的优势,在高压缩比的情况下能够保留良好的图像质量。

英文摘要 Aiming at the problem of large amount of medical image and the harsh requirements of memory and bandwidth, this paper proposed a new medical image compression approach based on double compression protocol. First, it used square network to reduce the size of images. Then, for each pixel of the image, it chose the optimal amplification method and embedded the corresponding image pixels by digital watermarking technique. Finally, it further compressed the watermark image by JPEG-LS lossless compression to get the final compression image, storaged and transmitted them. Through the experiment for MR and CT two types of medical image, the results show that, compared with other methods, this proposed method provides significant improvements and has ensured a better preservation of the image quality notably for high compression ratios.
