Description: 图像在传输过程中，传递函数对高频成分有衰减作用，造成图像模糊，细节轮廓不清楚。图像锐化就是补偿图像的轮廓，增强图像的边缘及灰度跳变的部分，使图像变得清晰。亦分空域处理和频域处理两类[3]。-Image in the transmission process, the transfer function of the role of high frequency components are attenuated, resulting in image blurring, the details of the outline is not clear. Image sharpening is the outline of the image compensation, edge enhancement and gray-scale image of the hopping part of the image became clear. Also sub-space and frequency domain processing to deal with two types of [3]. Platform: |

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: |
