Mahotas MKL or GPU support

[mallic...@gmail.com]

HI,

I am new to Computer Vision, creating a image search application using Zernike Moments as feature

I would like to know below

1) Is mahotas support MKL or GPU if yes how to enable it or where can i get these binaries

2) What is the relation of pixel intensity with ZM

please help me as i am stuck and the project is at halt

Observation

Same image with different intensity produces largely different ZM

Only through the operations that it uses numpy for (which is a minority of them).

Yes, that is to be expected. The Zernike moments are a deconstruction of the intensity image, not just the shape. Thus, different intensitities will produce different values. In some contexts, binarizing (by thresholding) is a good preprocessing step.

Cheers!
