08 Mar 2009 fast running mean fast recersive running mean in 2D or 3D. Author: Neil Hodgson
04 Feb 2009 CDF 9/7 Wavelet Transform 2-D image decomposition and reconstruction with cdf 9/7 wavelet proposed in jpeg2000 Author: Wang Tianhui

The performance is worse than Pascal's one. So I'm gonna stick with his version. Good job and nice implementation though.

30 Aug 2010 Faster 2D-Hadmard Tranform Fast 2D-Hadamard/Walsh Transform based on Simple Matrix Vector Multiplication Author: Andre Lee, Sin Yi

Hey i got it..have to change image to grayscale.

30 Aug 2010 Faster 2D-Hadmard Tranform Fast 2D-Hadamard/Walsh Transform based on Simple Matrix Vector Multiplication Author: Andre Lee, Sin Yi

I have met with an error on class type when running the code. Towards the end, matlab cannot process Y = W*X*W/N...W is a double, my image X is a uint8...when i convert image X to double i got an error saying
??? Error using ==> mtimes
Input arguments must be 2-D.
Please enlighten me. Thanks.

The author has indeed fixed the code issues and added a understandable help section. Well done!

btw, the classname argument is never used in the code ...
