This study introduces a new method to measure similarities on two origin–destination (OD) matrices by spatially extending an image゛ssessment tool, the structural similarity index (SSIM). The new measurement, spatially weighted SSIM (SpSSIM), utilizes weight matrices to overcome the SSIM ...
Structure featureFast VO decomposition modelStructure ratioStructural similarity index measurementIt is inevitable for non-contact palmprint recognition to obtain the low resolution image when capturing the image, which leads to poor recognition accuracy. In order to solve this problem effectively, a ...
