面向对象方法在Quick Bird影像分类中的应用研究

Application of Object-oriented Method in Quick Bird Image Classification

选取Quick Bird影像,以目视判读法作为精读评价的参考标准,对基于像元值的监督分类和非监督分类法、面向对象分类法进行了分析比较。结果表明,使用面向对象方法能显著提高Quick Bird影像分类精度。

With the visual interpretation method as the reference standards for intensive evaluation,the pixel value-based supervised method,non-supervised method and object-oriented method for the Quick Bird image classification were compared.The result indicated that the object-oriented method could significantly improve the classificaticn precision of Quick Bird image.
