A Knowledge-Based Target Recognition Method For Remote Sensing Image

This paper proposed a knowledge-based target bridge detection method from remote sensing images. Firstly, the prior knowledge about bridge can supervise the low and middle image processing and analysis to detect the edges of bridges and riversides. Secondly, knowledge about the different characters of the bridge edges and riverside edges was used to wipe off the riverside edges and remain the lines of bridges, so that the purpose of recognition on bridge can be achieved. The method was tested on spot remote sensing images and the result shows it can detect the bridges exactly from images.
