multidimensional discrete wavelet transform

Question

can anyone tell me the correct method to use the getOutputValue function in the following link? Also, how does the author get the 2nd and 3rd image from the code.

Okay, usage:

I haven't tried it yet, but from what I get you simply call getOutputValue() to get one result. The parameter is a vector containing the "coordinates" (based on the number of dimensions in your input).

Images:

In this example, the author obviously used the image data as the discrete values, e.g. a black pixel would be 0 and a white pixel would be 255 with all other shades of grey being inbetween (default 8 bit grayscale image).

He then used the output signal/result to recreate a image (i.e. interpret the values as pixels once again).
