实现图像的无损压缩
该程序主要实现图像的无损压缩,具体算法包括:
(1)整数小波变换+SPIHT无损压缩
其中整数小波可以采用JPEG2000提供的5-3小波,也可以采用S+P变换,本程序均已给出。
(2)DPCM+算术编码
DPCM采用的是JPEG中采用的方法;
(3)JPEG-LS标准
JPEG-LS的无损压缩性能非常好,超过JPEG2000。(The program mainly realize lossless image compression, the specific algorithm include: (1) integer wavelet transform SPIHT Integer Wavelet lossless compression which can be used to provide the 5-3 wavelet JPEG2000, can also adopt the S P transform, the procedures are given. (2) DPCM arithmetic coding DPCM is used in JPEG methodology (3) JPEG-LS standard JPEG-LS lossless compression of very good performance, more than JPEG2000.)

Gaussian
打开24位彩色bmp文件, 显示该图像
将图像内容顺时针旋转90度后显示出来
将图像分成等大小的4块,将第1和第3块像素互换后保存
将旋转后的图像转换成灰度图像显示,并保存
对灰度图像求Sobel边缘图,显示出来,并保存
对灰度图像进行Gaussian平滑,并保存(需要体会平滑的作用)
对灰度图像进行2值化(Open 24-bit color bmp files, displays the image will rotate clockwise image content displayed image is divided into four equal-sized 90 degrees, the first and three pixels after swap to save the rotated image conversion ashes of the image display, and save images to grayscale seeking Sobel edge map is displayed, and save the gray image Gaussian smoothing, and save (experience required smoothing effect) grayscale image binarized)
