How to use DCT to create feature vectors for neural networks?

I want to use DCT to create feature vectors for gray images and then use it for pattern recognition using neural network. Is there any example or a guide that may help me? thank you

Answer 1

[Walter Roberson]

Step 1:

Read the image.

Step 2:

call dct() on the image.

Step 3:

Use reshape() on the result of step 2, to turn the results of dct( ) into a vector

Step 4:

Use the vector as input to a neural network.
