Nina:

Your image size is not a factor of 4, neither 146 nor 234. You should either resize the image or use other downsampling factors.

Shanmugam:

m & n define the size of filter and cannot be set to 1.

Hillol:

d1 and d2 does not have any effect on computational complexity, but m & n have direct relation. You may want to deduce m and n if you are not interested in high frequency features in your images.

Sherko:

To the best of my knowledge, there is no relationship between the size of the image and the filter bank. The number of scales and orientations are arbitrary and mostly dependent on your application and image content and if you are interested in high frequency features or not.

Sherko:

Selecting the downsampling factor is a trade-off problem, and it mostly depends on you input image and the application. For example, if you have a finely detailed image, you cannot choose a large downsampling factor, because you may loose information. But on the other hand, a smaller downsampling factor leads to a larger feature vector, which is not good either.

But for sure, (d1 & d2 ) = 64,60 or (d1 & d2) = 32,30 for an image of size 128x120 is too much! I would rather using a lower downsampling factor, like 4, and then apply a dimensionality reduction approach to reduce the feature vector size.

Thank you for your comment. I sent you the paper.

Good day, Sir! I am currently using the gaborFeatures function. I always get this error: A(I) = X: X must have the same size as I (pointing to this line: featureVector(((c-1)*s+1):(c*s)) = gaborAbs;). My image size is 146x234. Does that have anything in relation to the error I get? I am using d1 and d2 = 4.Thank you!

By the way, I am using d1 and d2 = 4. Your reply will be very helpful. Thank you!
