Description: 提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定
医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。-Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.

Description: 图像压缩主要目的是为了节省存储空间，增加传输速度。图像压缩的理想标准是信息丢失最少，压缩比例最大。不损失图像质量的压缩称为无损压缩，无损压缩不可能达到很高的压缩比；损失图像质量的压缩称为有损压缩，高的压缩比是以牺牲图像质量为代价的。压缩的实现方法是对图像重新进行编码，希望用更少的数据表示图像。-The main purpose of image compression to save storage space, increase the transmission speed. The ideal image compression standard is a minimum loss of information, the maximum compression ratio. Compression without loss of image quality is called lossless compression, lossless compression can not achieve high compression ratio loss of image quality and compression is called lossy compression, high compression ratio at the expense of image quality for the price. Compression of the image is re-encoded data that wish to use fewer images. Platform: |
