DIBR synthetic image quality evaluation method based on cavity and contour amplification

The invention belongs to the field of free three-dimensional imaging and quality evaluation, and aims to effectively evaluate the quality of DIBR synthetic views and promote the development of free viewpoint three-dimensional videos. Therefore, the technical scheme adopted by the invention is as follows: the DIBR synthetic image quality evaluation method based on cavity and contour amplification comprises steps that according to the difference between a watershed algorithm and an image, a cavity and a contour amplification region in a virtual view are extracted, and the cavity and the contouramplification region are effectively evaluated by using a quality evaluator in the invention, so that the aim of effectively evaluating the quality of the DIBR synthetic view based on the drawing technology of the depth image is fulfilled. The method is mainly applied to free three-dimensional imaging and quality evaluation occasions. 本发明属于自由立体成像和质量评价领域，为实现有效评价DIBR合成视图的质量，促进自由视点立体视频的发展。为此，本发明采取的技术方案是，基于空洞和轮廓扩增的DIBR合成图像质量评
