- Abstract: Land cover (LC) segmentation plays a critical role in various applications,
including environmental analysis and natural disaster management. However,
generating accurate LC maps is a complex and time-consuming task that requires
the expertise of multiple annotators and regular updates to account for
environmental changes. In this work, we introduce SPADA, a framework for fuel
map delineation that addresses the challenges associated with LC segmentation
using sparse annotations and domain adaptation techniques for semantic
segmentation. Performance evaluations using reliable ground truths, such as
LUCAS and Urban Atlas, demonstrate the technique's effectiveness. SPADA
outperforms state-of-the-art semantic segmentation approaches as well as
third-party products, achieving a mean Intersection over Union (IoU) score of
42.86 and an F1 score of 67.93 on Urban Atlas and LUCAS, respectively.

- When Segmentation Meets Hyperspectral Image: New Paradigm for Hyperspectral Image Classification [4.179738334055251]
Hyperspectral image (HSI) classification is a cornerstone of remote sensing, enabling precise material and land-cover identification through rich spectral information.
While deep learning has driven significant progress in this task, small patch-based classifiers, which account for over 90% of the progress, face limitations.
We propose a novel paradigm and baseline, HSIseg, for HSI classification that leverages segmentation techniques combined with a novel Dynamic Shifted Regional Transformer (DSRT) to overcome these challenges.

We focus on a relatively under-explored task setting, long-tailed semantic segmentation (LTSS)
We propose a dual-metric evaluation system and construct the LTSS benchmark to demonstrate the performance of semantic segmentation methods and long-tailed solutions.
We also propose a transformer-based algorithm to improve LTSS, frequency-based matcher, which solves the oversuppression problem by one-to-many matching.

This study explores the effectiveness of a Cut-and-Paste augmentation technique for semantic segmentation in satellite images.
We adapt this augmentation, which usually requires labeled instances, to the case of semantic segmentation.
Using the DynamicEarthNet dataset and a U-Net model for evaluation, we found that this augmentation significantly enhances the mIoU score on the test set from 37.9 to 44.1.
