A sparsity augmented probabilistic collaborative representation based classification method
This is an incremental improvement for image recognition tasks, potentially benefiting researchers and practitioners in computer vision.
The paper tackles image recognition by proposing a sparsity augmented probabilistic collaborative representation based classification (SA-ProCRC) method, which combines dense and sparse coefficients to classify test samples without explicit reconstruction residuals, achieving promising results on face and scene images.
In order to enhance the performance of image recognition, a sparsity augmented probabilistic collaborative representation based classification (SA-ProCRC) method is presented. The proposed method obtains the dense coefficient through ProCRC, then augments the dense coefficient with a sparse one, and the sparse coefficient is attained by the orthogonal matching pursuit (OMP) algorithm. In contrast to conventional methods which require explicit computation of the reconstruction residuals for each class, the proposed method employs the augmented coefficient and the label matrix of the training samples to classify the test sample. Experimental results indicate that the proposed method can achieve promising results for face and scene images.
