Abstract

Effective image representation is critical for a variety of visual recognition tasks. In this paper we propose to use hierarchical features for image representation by exploiting the combined strengths of the wavelet transform and LBP (WaveLBP). To be specific, we build up image description under a hierarchical framework based on low-dimensional WaveLBP features with dense spatial sampling, which not only extracts multi-scale oriented features and local image patterns, but also captures multi-level (the pixel-level, patch-level and image-level) features. Experimental results show that the proposed WaveLBP based image description achieves competitive classification accuracies for three different visual recognition tasks.
