Image processing method and device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses an image processing method and device. The method comprises the following steps: respectively inputting a first image and a second image into corresponding coding networks for feature extraction to obtain feature data of different coding levels, and then combining the feature data of the same coding level to obtain target feature data of different coding levels, the target feature data of different coding levels are sequentially subjected to superposition operation and decoding operation to obtain the decoded data, and the difference data between the first image and the second image is determined according to the decoded data, so that two input images can be better distinguished during coding, and the features of multiple coding levels are fused during decoding to obtain the target feature data of different coding levels. According to the method, the abstract high-level features, the concrete low-level features and the features of all the middle levels between the abstract high-level features and the concrete low-level features can be utilized, the difference is efficiently extracted from the two images, and the accuracy and efficiency of discovering the difference between the images are improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, an image processing device, a computer device, and a computer-readable storage medium. Background technique [0002] With the development of computer technology, computer detection has begun to be applied to the comparison task of two phases of remote sensing images. For example, new building detection is the most common one, which is mostly used in land management and law enforcement. [0003] Compared with the new construction inspection, the ground-breaking construction inspection covers a wider range. It not only includes the detection of new buildings, but also includes the detection of building demolition, building reconstruction, agricultural land, cultivated land, forest land, construction site, new roads, coastline changes, etc. The application scenarios have also expanded from a single land management law enforcement t...

Problems solved by technology

[0004] The applicant found through research that most of the changed areas need to be manually extracted, which not only has the problem of missing more mentions, but also has low efficiency, and the general computer detection method is not ideal due to the unsatisfactory number of found and corrected changed areas. really applied to the actual scene
