Abstract:

To solve the structure information loss issue on sparse representation for accurate image classification, a new method based on structure constrain sparse
representation was proposed. The training samples after downsampling and extracting histogram of orientated gradient (Hog) were utilized to construct sparse linear coding model.
The sparse coefficients were solved on the training samples by distribution structure information constrain and 1minimization, and image was classified by sparse coefficient
mean.  Experimental results with COREL dataset demonstrated that the proposed method can obtain the good recognition performance. Comparing with nonstructure constrain sparse
representation, the proposed method greatly improves the accuracy of image classification.

Key words: distribution structure constrain, sparse representation, image classification
