Spatial Pooling Strategies for Image Quality Assessment Based on Local Structural Information
Dong Yin · 2011
A spatial pooling strategies(SPS) for image quality assessment(IQA) is proposed,which obtain a weight map from local structural information(LSI) of the reference image.The reference image is first smoothed with a Gaussian kernel,and the LSI is extracted from the smoothed image.A weight map is derived from the LSI using a non-zero procedure.PSNR and SSIM obtained in the experiments show effectiveness of the proposed method for a wide range of image distortion types.
