摘要	The global features of laser-dazzling images, the local features of targets and the distribution characteristics of laser spots are analyzed.A new algorithm composed of Weighted Feature Similarity (WFSIM) is proposed for the assessment of laser-dazzling effects. The method firstly uses the global features including luminance, contrast, edge definition and local feature-point maintainability to obtain the assessment model. Then, it computes the weighting factors, such as the saturated pixel number, signal to noise ratio and spot visual impotence based on the size, intensity and position of the laser spot. Based on the above results, a modified assessment algorithm can be constructed and a normalized evaluation can be implemented. An experiment platform of laser active imaging and recognition system is built for laser-dazzling images under different laser intensities, different background intensities and different spot positions. The proposed WFSIM algorithm is used to evaluate obtained laser-dazzling images. In terms of experiment results, the WFSIM algorithm shows good feasibility and rationality as comparing with Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR) and Structural Similarity (SSIM) image quality assessment methods. The evaluation results is consistent with the subjective human visual perception.
