Research On The Technologies Of Image Fragments Reassembly Based On Energy

Image fragment reassembly is to make irregular fragment to become initial full model. Image fragment mosaic method research means the use of a computer to complete the study of this splicing process. This technology can be widely used in archeology, criminal case evidence collection and so on. In the large and irregular mosaic fragments, no doubt it will be time-consuming in manual methods, and the task can not be completed well. Otherwise, using computer-aided, efficiency and quality can be well assured.In this paper, Image fragment mosaic method is studied. This paper outlined concrete steps of fragment mosaic method, including the image preprocessing, image fragment matching theory and technology solutions, and the mosaic of image fragments achieved.This paper proposes a method of image fragments contour matching based on energy, from the second chapter, the paper begins the preparatory work of relevant aspects. Firstly, the preprocessing of image fragments is studied introduction, followed by study and discussion of the image matching theory. Finally, we determine the image fragments matching principle, and realize the matching of two images fragment. In this paper, the use of multi-scale methods and the longest common subsequence algorithm controls the accuracy and efficiency of image fragments contour matching, achieving a simple and efficient result.The program in the paper is realized by MATLAB completing image fragment reassembly. Experiments show that the algorithm has a good effect.
