With the improvement of the remote sensing images' resolution,the presence of shadow in High-resolution imagery is much more evident,which will be a serious obstacle for image interpretation.Therefore,the shadow identification is important in image analysis.Shadow areas are easy to be confused with other classes in RGB space,while having lower brightness,higher saturation,and greater hue value.In view of this,this paper proposes a shadow detection method based on a novel shadow index.The shadow index highlights the shadow areas,while suppressing the nonshadow areas.The histogram thresholding segmentation is performed by Ostu algorithm to acquire the shadow detection result.Experimental results demonstrate that the proposed approach can separate shadow from nonshadow effectively.

Key words: shadow detection;shadow index;color space;high resolution
