Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a satellite image target intelligent recognition system and method based on an improved SSD algorithm. Background technique [0002] With the rapid development of high-resolution satellites and the rapid increase of high-resolution remote sensing image data, research on remote sensing image target recognition algorithms under big data has become an urgent need. Compared with the traditional global and local feature extraction methods, deep learning, which has been developed in recent years, can extract features independently, and the extracted features have good adaptability, avoiding the complicated process of manual design and feature extraction. [0003] In practical applications, remote sensing images have the characteristics of large format and low resolution compared with conventional natural scene pictures. A series of intelligent recognition algorithm...
