沈叶健 %A 徐守时 %J 计算机应用 %D 2006 %I %X An effective method for dam recognition was proposed. First, the original image was sampled according to the resolution of souree image. The large upstream water area of dam was obtained by using the gradient histogram and the region growth, and the large water area was expressed through the Freeman code. The downstream water was pursued and the possible dam region was divided preliminary. Then one group of features of dam was extracted. The algorithm has the characteristic of high recognition rate, good extension and so on. Experimental results show that this proposed method is effective for dam recognition in the visible images. %K object recognition %K chain code %K corner
