I'm new to texture analysis. I was experimenting with some pretty standard filter banks when I came across something strange.
The data I'm working with is a 2D matrix of dimensions: 379x422.
When I put the data through the filterbank, the dimensions of the responses were 427x470.
The filterbank I'm working with is the The Leung-Malik (LM) Filter Bank. It consists of first and second derivatives of Gaussians at 6 orientations and 3 scales making a total of 36; 8 Laplacian of Gaussian (LOG) filters; and 4 Gaussians.
Essentially, I'm just wondering why the responses have more data than the original? What's going on here?
