Problems solved by technology

[0003] The multi-focus image fusion method in the prior art is based on the prediction and processing of the convolutional neural network, which also needs to perform binary segmentation, hole removal, watershed and other operations on the image, and some related data need to manually extract features. This process is quite cumbersome

Abstract

The invention provides a multi-focus image fusion method and device, and the method comprises the steps: obtaining a target image, carrying out the Gaussian blur processing and binarization processing of the target image, and obtaining a Gaussian image and a true value image corresponding to the target image; generating an anti-truth value image corresponding to the truth value image, wherein the anti-truth value image and the truth value image are in a complementary relationship; based on the target image, the Gaussian image, the truth value image and the anti-truth value image, generating a first focusing image and a second focusing image corresponding to the target image, the first focusing image and the second focusing image being in a complementary relationship; the first focus image and the second focus image are input into a pre-trained image fusion network, a decision diagram output by the image fusion network is obtained, and the decision diagram is a binary image predicted by the image fusion network; and fusing the first focus image, the second focus image and the decision diagram to obtain a multi-focus fused image. By applying the method provided by the invention, the multi-focus image fusion process can be simplified.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a method and device for fusion of multi-focus images. Background technique [0002] Image fusion technology is a visual information fusion technology, which is an extended branch of information fusion. Image fusion is mainly in the same scene, the content information obtained by multi-source sensors from multiple channels is processed by various methods, and the useful content information in each image is extracted, and finally a single image with high quality and rich information is fused. Multi-focus image fusion is one of the important branches of image fusion. It uses a single sensor device to fuse image content information obtained by multiple focusing in a scene. [0003] The multi-focus image fusion method of the prior art is based on the prediction and processing of the convolutional neural network, which also needs to perform operations such as bin...
