改进投影变换和保留结构特征的拼接图像修复算法
Splicing image completion algorithm to improve projection transformation and reserve structure feature
摘要
Abstract
The splicing image contains the irregular boundary,and its rectangular shape is acquired by means of image cut-ting and pixel supplementary. Since the direct cutting mode may discard the pixels around the image,the image completion algo-rithm based on sample block has the discontinuous and incomplete object structure,and the image completion method based on Markov random field model has broad search scope and low efficiency,a method of improving the projection transformation is proposed to realize the space transformation of the splicing image,so as to reduce the vacant areas around the spliced image, and combined the seam segment carving algorithm for boundary feature reservation to perform the rectangular expansion for the splicing image so as to realize the reservation of the pixels around the splicing image and object structure information inside the image. The experimental results show that the proposed method can realize the maximum visual angle of the splicing image,and rectangular completion of the splicing image without the visual visible deformation.关键词
