LESC: Superpixel cut‐based local expansion for accurate stereo matching

open access: yesIET Image Processing, 2022
The rapid estimation of the accurate disparity between pixels is the goal of stereo matching. However, it is very difficult for the 3D labels‐based methods due to huge search space of 3D labels, especially for high‐resolution images.

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 ...

Superpixels, Occlusion and Stereo [PDF]

open access: yes2011 International Conference on Digital Image Computing: Techniques and Applications, 2011
Graph-based energy minimization is now the state of the art in stereo matching methods. In spite of its outstanding performance, few efforts have been made to enhance its capability of occlusion handling. We propose an occlusion constraint, an iterative optimization strategy and a mechanism that proceeds on both the digital pixel level and the super ...

Superpixel-Based Unsupervised Hyperspectral Unmixing [PDF]

open access: yes, 2018
Recently, superpixel-based approaches have been proposed for hyperspectral unmixing. The basic assumption of this approach is that the superpixel over-segmentation segments the image into small homogeneous areas.

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 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.
