This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

kdtree
k-d树的matlab程序,包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo
scripts(kdtree_demo.m & kdrange_demo.m),很实用(
This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions.
Included are the source code files in kdtree/src, as well as precompiled
mex files for the following systems:
- Mac OS X (Matlab 6.5)
- Redhat Linux (Matlab 6.5)
- Windows (Matlab 6.1)
Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m).
The new features added June 2004:
+ You can now use N dimensional data points, where N>3.
+ Use KDTREEIND to return the index value to the closest point,
instead of the closest point values.
+ KDRANGEQUERY can now return these index values as well.
