Nabeel Mohammed and David McG. Squire,
Improved Texture Features for CBIR using Response Scaling
and Locally Normalised Convolution,
In Proceedings of the 11th International Workshop on
Content-Based Multimedia Indexing,
Veszprém, Hungary, pp. 143-148, June 17-19 2013.
Independent Component Filters have been shown to be more
effective for collection-specific CBIR than generic texture features
such as Gabor filter banks. This paper describes changes to a filter
selection method and feature extraction process that significantly
improve the performance of both ICF- and Gabor filter-based features.
We describe, and correct a possible oversight in, a previously
published variance-based filter selection method. We also propose the
use of locally normalised convolution as a technique to better match
texture patterns in images with local intensity differences. We
evaluate these changes using a simple CBIR system and our Precision and
Recall results are significantly better than those previously
published.
