Multiscale superpixel segmentation-based band expansion for change detection
Remote Sensing Letters, 2023Change detection (CD) for remotely sensed images has gained great relevance in the last decade due to an increase in the number of Earth Observation (EO) missions, improved temporal resolutions, and open data policies. However, efficient exploitation and integration of spatial information for CD remains a challenging issue.

Multiscale superpixel-based fusion framework for hyperspectral image classification
2018 Fifth International Workshop on Earth Observation and Remote Sensing Applications (EORSA), 2018Since it is usually difficult and time-consuming to obtain sufficient labeled samples in practice, the samll number of sample is one of the challenging issue for hyperspectral image classifiction. Fortunately, due to the spatial correlation of the surface of the materials, it is feasible to improve classification performance from the perspective of ...

This letter introduces a new spectral–spatial classification method for hyperspectral images. A multiscale superpixel segmentation is first used to model the distribution of classes based on spatial information. In this context, the original hyperspectral image is integrated with segmentation maps via a feature fusion process in different scales such ...

A Multiscale Superpixel-Guided Filter Approach for VHR Remote Sensing Image Classification
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019This paper presents a novel multiscale superpixel-guided filter (MSGF) approach for very high resolution (VHR) remote sensing image classification. Different from the traditional guided filter (GF) classification method, the proposed method utilizes a guidance image that constructed from the superpixel segmentation image, which is capable to provide ...

Recently, the superpixel segmentation is introduced into the hyperspectral image (HSI) classification to exploit the spatial information. However, the size of superpixel is hard to determine since small superpixels lack enough spatial information and large superpixels usually result in error segmentation.
