Abstract:

To achieve autosorting of image sequence in image mosaic,we propose an image sequence auto-sorting algorithm based on Hu vector similarity.A Hu vector is constructed by seven Hu moments of the image and the Euclidean distance between two Hu vectors is used to describe the similarity of the two images,by which all the images in sequence are sorted.Experimental results show that the proposed algorithm can realize autosorting of the chaotic sequence of images effectively even if there are some images with different sizes or rotation in the sequence.
