A Superpixel Boundary Optimization (SBO) Framework Based on Information Measure Function

open access: yesIEEE Access, 2020
Superpixel is an essential tool for computer vision. In practice, classic superpixel algorithms do not exhibit good boundary adherence with fewer superpixels, which will greatly hamper further analysis.

Superpixel Nonlocal Weighting Joint Sparse Representation for Hyperspectral Image Classification

open access: yesRemote Sensing, 2022
Joint sparse representation classification (JSRC) is a representative spectral–spatial classifier for hyperspectral images (HSIs). However, the JSRC is inappropriate for highly heterogeneous areas due to the spatial information being extracted from a ...

Multiscale Weighted Adjacent Superpixel-Based Composite Kernel for Hyperspectral Image Classification

open access: yesRemote Sensing, 2021
This paper presents a composite kernel method (MWASCK) based on multiscale weighted adjacent superpixels (ASs) to classify hyperspectral image (HSI). The MWASCK adequately exploits spatial-spectral features of weighted adjacent superpixels to guarantee ...

Superpixel based Feature Specific Sparse Representation for Spectral-Spatial Classification of Hyperspectral Images

open access: yesRemote Sensing, 2019
To improve the performance of the sparse representation classification (SRC), we propose a superpixel-based feature specific sparse representation framework (SPFS-SRC) for spectral-spatial classification of hyperspectral images (HSI) at superpixel level.

A Two-Stage Gradient Ascent-Based Superpixel Framework for Adaptive Segmentation

open access: yesApplied Sciences, 2019
Superpixel segmentation usually over-segments an image into fragments to extract regional features, thus linking up advanced computer vision tasks. In this work, a novel coarse-to-fine gradient ascent framework is proposed for superpixel-based color ...

Superpixel Boundary-Based Edge Description Algorithm for SAR Image Segmentation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Although various methods can effectively segment synthetic aperture radar (SAR) images, we found that the method combining superpixel and image edge information can get better results. To solve the problem that common SAR image segmentation methods often

Superpixel Segmentation of Marine SAR Images Based on Local Fuzzy Iteration and Edge Information for Target Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Most of the existing superpixel segmentation-based synthetic aperture radar (SAR) target detection algorithms cannot keep the independence of small targets under complex background, especially when the size of the targets varies greatly.
