A real-time recognition algorithm of bridges above water in aerial images

Recognition of bridges plays important roles in both military and civil fields. The existing researches have got some achievements, but most of them can only be applied in some limited images. What's more, all of them are simulation algorithms based on PC, so they cannot be used in real-time applications. A real-time knowledge-based automatic recognition algorithm of bridges was introduced. This algorithm is based on FPGA and DSP, which can be widely used in aerial images or remote sensing images. It can be applied to not only close shot images, but also distant shot ones. At the same time, it can recognize several bridges in one picture.
