Description: 通过阅读这份文档,能够对 JPEG 图形压缩有一定感性的认识, 但其数学原理不需要搞清. 能够通过这, 开始写自己的编码/解码程序. 或者看懂以有的代码. 对有损图形压缩有进一步了解.自己能够改良 JPEG, 比如增加透明色的支持, 加快 JPEG 的解码速度.
-By reading this document to JPEG image compression to a certain emotional understanding, it does not need to understand the mathematical principles. through this, begin to write their own encoding/decoding process. or to read some code. graphics compression harmful to the further understanding. own JPEG can be improved, such as increasing transparency color support and accelerate the speed JPEG decoders.

Description: 基于LSB的图像中数据加密隐藏算法程序
图像的组成无非是一些字符串或者一些字节组成的字符串,然而,每一个字节数据位的重要度并不是一样的,两个相邻字节往往只有低位是不一样的。例如:00100110和00100111代表了两个不同渐变度的红色,但是就人眼是分辨不出来的。最低有效位LSB算法,就是利用这一点,达到图像压缩,或者数字水印的功能。 -LSB of the image-based data encryption to hide the image composition algorithm procedure is nothing more than some number of bytes or string composed of string, however, one byte for each data bit is not an important degree of the same, and two adjacent words section, usually only low level is not the same. For example: 00100110 and 00100111 represent the gradient of two different degrees of red, but on the human eye is not out to tell. Least significant bit LSB algorithm, is to take advantage of this point, to achieve image compression, or digital watermark feature. Platform: |
