Matlab：让做什么工作?
• Experiment with wavelet compression for cameraman.tif.Evaluate the image quality for different thresholds.
• Convert cameraman.tif to jpeg using different levels of compression.Compare the relative sizes and quality of the resulting images with those you obtained for wavelet compression.
• Use the haar wavelet inverse transform to double the size of the cameraman image.(Apply the inverse transform but with the horizontal,vertical and diagonal details equal to 0.) Compare the result with duplicating the pixels in two-by-two blocks.
• Compare the optimal wavelet packet representation with the wavelet representation for cameraman.tif.Are the representations different?If so,how do they vary?

大致意思：
1.对于图像cameraman.tif,利用小波压缩技术做试验,对于不同的阈值估算图像的质量；
2.用不同压缩水平把图像cameraman.tif转换为JPEG格式,比较这些结果图像的大小和质量；
3.利用haar小波反变换使图像大小加倍.……
4.比较最优小波包和小波对图像cameraman.tif的表达结果,是否存在不同?有何变化?
不是学图像处理的,只能大概帮翻译一下,祝顺利.
BTW,你用matlab难道不认识这些?
