An Automatic Detection Algorithm of Bridges above Water in Aerial Images
Abstract:
An automatic detection algorithm of bridges above water in aerial images is proposed. Firstly, aerial image is binarized based on gradient mean square variance, and binary image is denoised based on pixel density. Then connective areas are labeled in the binary image based on pixels to extract water area. Finally, bridge area is detected based on gray information. Experiments show this algorithm is effective in automatic detection of bridges above water in aerial images.
