A novel reconstruction method to improve the recognition of license plate texts of moving vehicles in real traffic videos is proposed, which fuses complimentary information among low resolution (LR) images to yield a high resolution (HR) image. Based on the regularization super-resolution (SR) reconstruction schemes, this paper first introduces a residual gradient (RG) term as a new regularization term to improve the quality of the reconstructed image. Moreover, L1 norm is used to measure the residual data (RD) term and the RG term in order to improve the robustness of the proposed method. Finally, the steepest descent method is exploited to solve the energy functional. Simulated and real acquired video sequence experiments show the effectiveness and practicability of the proposed method and demonstrate its superiority over the bi-cubic interpolation and discontinuity adaptive Markov random field (DAMRF) SR method in both signal to noise ratios (SNR) and visual effects. 展开更多
