“…In the past decade, edge-preserving filtering such as the guided filter (GF) has proven to be effective in different image processing applications, for example in image smoothing/enhancement, image fusion [26], dehazing [27], image segmentation [28], saliency detection [29], etc. Theoretically, considering the spatial representation of a guidance image, GF is capable of transferring the intrinsic properties of the guidance image, especially its structures, to a filtered output, which can smooth the noise probabilities, but also preserve the real object boundary in the filtered image [30].…”

In this article, a novel feature selection-based multi-scale superpixel-based guided filter (FS-MSGF) method for classification of very-high-resolution (VHR) remotely sensed imagery is proposed. Improved from the original guided filter (GF) algorithm used in the classification, the guidance image in the proposed approach is constructed based on the superpixel-level segmentation. By taking into account the object boundaries and the inner-homogeneity, the superpixel-level guidance image leads to the geometrical information of land-cover objects in VHR images being better depicted. High-dimensional multi-scale guided filter (MSGF) features are then generated, where the multi-scale information of those land-cover classes is better modelled. In addition, for improving the computational efficiency without the loss of accuracy, a subset of those MSGF features is then automatically selected by using an unsupervised feature selection method, which contains the most distinctive information in all constructed MSGF features. Quantitative and qualitative classification results obtained on two QuickBird remotely sensed imagery datasets covering the Zurich urban scene are provided and analyzed, which demonstrate that the proposed methods outperform the state-of-the-art reference techniques in terms of higher classification accuracies and higher computational efficiency.
