[0101] Here, n is a positive integer.

[0102] Obtain the mask (mask) image corresponding to the image to be repaired, mark the part that needs to be repaired as 0, and mark the part that does not need to be repaired as 255, and construct a Gaussian pyramid of the image to be repaired and the corresponding mask image until there is no 0 in the mask. Here, n is a positive integer.

[0103] In step 102, the images of each layer in the n-layer Gaussian pyramid are completed by using a block matching method, and the completed real images of each layer are obtained.

Abstract

The disclosure relates to an image completion method and device. The method includes the following steps: generating n layers of Gauss pyramids on the basis of an image to be restored, n being a positive integer; through a block matching method, completing images of each of the n layers of Gauss pyramids, and obtaining an actual image of each layer after completion; generating a generative network of an adversarial network on the basis of the n image of the n layers of Gauss pyramids and the actual images of all the layers; and on the basis of the n image and the generative network, completing the image to be restored, and obtaining a completed image after completion. According to the technical scheme, the generative network is obtained through a Gauss pyramid of the image to be restored, the actual images of all layers of Gauss pyramids and the adversarial network, so a clear and complete image high in resolution can be generated quickly. Therefore, the resolution of the completed image is improved, learning about the generative network is accelerated, and a more real image can be obtained.
