wavelet

I am implementing an android application that will verify signature images , decided to go with the Discrete wavelet transform method (symmlet-8) the method requires to apply the discrete wavelet transform and separate the image using low-pass and high-pass filter and retrieve the wavelet transform coefficients.

the equations show notations that I cant understand thus can't do the math easily , also didn't know how to apply low-pass and high-pass filters to my x and y points.

is there any tutorial that shows you how to apply the discrete wavelet transform to my image easily that breaks it out in numbers?

thanks alot in advance.

Do I need to store a generic rotation point/radius for rotating around a point other than the origin for object transforms?

as seen on Game Development - Search for 'Game Development'
I'm having trouble implementing a non-origin point rotation. I have a class Transform that stores each component separately in three 3D vectors for position, scale, and rotation. This is fine for local rotations based on the center of the object. The issue is how do I determine/concatenate non-origin… >>> More
