A method for repairing local missing in the background of virtual multi-view ship images
Aiming at the problem of local missing background in virtual multi view ship image generation,a method for repairing local missing background in virtual multi view ship image is studied.Based on the multi view image and corres-ponding disparity map of the ship,a reverse mapping method is used to generate a virtual view image of the ship.After elim-inating artifacts,the virtual view image of the ship is synthesized into a virtual multi view ship image.Using graph cutting method,construct Gibbs energy equations corresponding to foreground and background labels of virtual multi view ship im-ages,determine the labels of each pixel,and automatically segment virtual multi view ship images.Using the fast marching algorithm,local missing points in the image background are sequentially repaired in order from outside to inside,achieving local missing repair of virtual multi view ship image background.The experimental results show that this method effectively repairs local missing points in the background of virtual multi view ship images,and the peak signal-to-noise ratio of the re-paired image pixels is higher than 25 dB.
