ï»¿Extracting river information from remote sensing images is of great importance in the investigation and monitoring of water resources and navigation of ships. In order to extract the river target from remote sensing images more accurately, a method based on image decomposition and distance regularized CV (Chanâ€“Vese) model is proposed. Firstly, the remote sensing image is decomposed based on tensor diffusion. The original image is decomposed into a cartoon image and a texture image and the river is contained in the cartoon part. Secondly, the cartoon image is segmented based on the distance regularized CV model. Experimental results show that, the method proposed is more accurate in extracting the river target comparing with 6 other methods including image segmentation based on CV model, region-scalable fitting energy level set model, bias field correction level set model and some methods based on image decomposition and active contour model.
