Craters are the most abundant landform on the planet surface, which could provide fundamental clues for planetary science. Due to variations in the terrain, illumination, and scale, it is challenging to detect craters through remote sensing images and it requires an effective crater feature extraction method. In this paper, we address this problem using Gist features, which can provide highly effective...
An approach is proposed to extend bilateral filtering to the vector case so as to simultaneously take spectral and spatial information into account by using spectral distances and multivariate Gaussian functions. To simplify the determination of the parameters of the corresponding covariance matrix, the data vectors are transformed to eigenspace through principal component analysis (PCA). By locally...
