Spectral Representation-Enhanced Multitask SAM for Cropland Parcel Delineation (opens in new tab)

Accurate cropland parcel delineation (CLPD) from remote sensing imagery is crucial for fine-scale agricultural monitoring. The recent segment anything model (SAM), as a foundational vision model, demonstrates remarkable generalization capabilities, presenting significant potential for CLPD. However, SAM’s design for RGB natural imagery limits its ability to model multispectral information effectively. To address these limitations, we propose a spectrally enhanced multitask segmentation framew...
