说明： JPEG2000 Haar and inverse Haar wavelet transform on images.And a threshold can be added during the compression, and after decompression the result can be seen with different thresholds.

haar wavelet transform (0, 2008-09-08)
Instructions:
haar.m: haar wavelet transform, only applied on rows
ihaar.m: inverse haar wavelet transform, only applied on rows
compression.m: compress the image data, first apply the haar wavelet transform on rows, and then on columns.
decompression.m: decompress the compressed image data, first apply the inverse haar wavelet transform on rows, and then on columns.
threshold.m: add a threshold to the image data,after the haar wavelet transform both on rows and columns.
NOTE: I applied the haar and inverse haar wavelet transform on columns by doing the same operations on the transposed matrix.
