Image retrieval method based on local projection andblock LBP feature
A projection method is applied to local image blocks through combinations with Vector Quantization(VQ) to generate the projection vector index histogram
which can efficiently represent the distribution and the spacial information of colors. Furthermore
a block-based local binary pattern(LBP) algorithm is proposed
which can effectively extract the structural model of block primitive
avoid instability
and reduce computations compared to the traditional methods. Finally
an image is partitioned into significant regions and non-significant regions based on its saliency map to give the features which are extracted from them more visual sense. Our proposed method is improving the performance by an average of 6.39% compared to the classical index histogram algorithm.
