A Similar-Curve Based Auto-sorting Algorithm for Panoramic Images

A sorting algorithm using similar-curve is proposed to automatically rearrange the input images in order, which is usually taken as a preprocessing step for mosaicing panoramic image. First, the similar curve of each input image is computed, and then, with the proposed quick match strategy, the similarities between any two images are calculated to construct a similarity matrix. By analyzing the similar curves and the similarity matrix, whether the input images should be sorted horizontally or vertically is judged and the images are automatically sorted in order along the judged direction. Experimental results demonstrate the effectivity of the proposed algorithm.
