[Program doc] lossless-image-compression-based-on-optimal.pdf.z DL : 0: The optimal predictors of a lifting scheme in the general n-dimensional case are obtained and applied for the lossless compression of still images using rst quincunx sampling and then simple row-column sampling. In each case, the e ciency of the linear predictors is enhanced nonlinearly. Directional post- processing is used in the quincunx case, and adaptive-length postprocessing in the row-column case. Both methods are seen to perform well. The resulting nonlinear interpolation schemes achieve extremely e cient image decorrelation. We further investigate context modeling and adaptive arithmetic coding of wavelet coe cients in a lossless compression framework. Special attention is given to the modeling contexts and the adaptation of the arithmetic coder to the actual data. Experimental evaluation shows that the best of the resulting coders produces better results than other known algorithms for multiresolution-based lossless image coding. - The optimal predictors of a lifting scheme in the general n-dimensional case are obtained and applied for the lossless compression of still images using rst quincunx sampling and then simple row-column sampling.

[Special Effects] imrotate DL : 0: 使用双线性插值的图像旋转，和本站的其余旋转不同，我的旋转不会使图像缺角，好处就是旋转后他的傅里叶变换的频域图也旋转同样的角度，同样可以用来处理矩阵，来做滤波器，我在做方向滤波器，有兴趣要的可以m我。-Using bilinear interpolation, image rotation, and the rest of the rotation is the rotation does not make the image Cutaway, the advantage is that the rotation after his Fourier transform frequency domain also rotates the same angle, can also be used to handle the matrix, do the filter, I was doing directional filter, interested to m.
