Abstract

General scene change detection determines the changes of a scene by using feature comparison of two continuous images that are above the fixed threshold. But existing algorithm detects scene change that was used in comparing the features of two images continuously, it usually takes a lot of time in decrypting the image data and false-detection problem occurs when there is an object motion or a change of illumination. In this paper, macroblock were used to extract the information directly from the MPEG compression area and suggests algorithm that will detect scene changes more effectively. Existing algorithm have shown numerous arithmetic problems that were improved in the proposed algorithm. The existing algorithm cannot detect the changes of a scene after analyzing the relationship of the previousand futureimages while the algorithm being proposed can detect the changes of a scene continuously and resolves the problem of false-detection. To this end, the data used in general were tested to prove that this algorithm would be able to detect the scene changes faster and more correctly than the existing ones. The performance of the suggested algorithm was analyzed based on the results of the experiment.
