In order to make full use of the spectral feature of the object, this paper proposes a classification method for remote sensing image based on G statistics of the object histogram. Image objects were obtained by multi-resolution image segmentation method. Then training objects were chosen from these objects. The histogram of the object was obtained with the adaptive gray level according to the spectral property. G statistics was used to measure the histogram distance between test object and training object which describes the heterogeneity of two objects. Minimum distance classifier was employed to get the image classification result. The experiment on the remote sensing image shows that the proposed method can improve the accuracy of the classification.
