| Abstract: | Low-altitude remote sensing is one of the most important methods to gain remote sensing image data,and feature point as a usual image feature can be extracted by many feature point operators.In this paper,according to characteristics of the low-altitude remote sensing digital images and the demand for practical application,the authors compared the common operators by three evaluation criteria for interest points as detecting speed,adaptability and extracting ability and provided the reference for choosing t... |
