...Among the diversity of stitching algorithm literatures, many researchers choose to assess the stitched images by either making comparisons subjectively [24, 14] or using conventional image quality assessment (IQA) metrics [12, 1]....

...Another way to evaluate stitching algorithm is to adopt classical IQA metrics to stitched images [1, 12] such as MSE (Mean Squared Error) [23], PSNR ((Peak Signalto-Noise Ratio) [17], SSIM (Structural Similarity index) [6] and VSI (Visual Saliency Induced index) [26]....
