Description
technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to an image stream-based near real-time remote sensing image online target detection method. Background technique [0002] With the rapid development of satellite remote sensing technology, especially the development of high-resolution remote sensing technology, multi-source, high-resolution remote sensing data is growing explosively, and the storage and processing of remote sensing data has encountered unprecedented challenges. In remote sensing image applications, such as military applications, users are often interested in the part of the image that contains the target. For these users, a large number of background images are invalid information, and the storage and processing of these data not only waste a large amount of storage and computing resources, but at the same time, the effective information is submerged in the massive data, making it more diffi...
