结合多种特征的高分辨率遥感影像阴影检测
Shadow Detection in High Resolution Remote Sensing Images Using Multiple Features
摘要
Abstract
To aim at the problem that shadow detection algorithms cannot simultaneously well detect partial-bright shadows and shadows in dark object, a kind of high resolution remote sensing images shadow detection method that combine a multiple features is proposed. The algorithm firstly combines principal component analysis, color features and histogram segmentation to construct the detection conditions of various thresholds, then integra various features of remote sensing image for initial detection, finally by analyzing the difference of the RGB models in the shadow and non shadow, uses the color characteristics to detect the shadow region. Experimental results show that the algorithm proposed in this paper can detect partial uses bright shadows and shadows in dark object effectively. Compared with the existing methods, the average total error rate goes from the level set method 31.85% down to 24.61% for partial shadow, and the average total error rate is reduced from the automatic detection method 37.75%to 23.30%for shadows in dark object.关键词
