RQ-PointNeXt: An End-to-End 3D Point Cloud Instance Segmentation Method for Field Cotton Boll Phenotyping

Accurate point-cloud segmentation of cotton organs is essential for precise phenotypic characterization. However, reliable instance segmentation of cotton bolls in field-derived point clouds remains challenging because foliage occlusion, contact between adjacent bolls and incomplete reconstruction obscure instance boun...

Low-Cost and Rapid Construction of 3D Point Clouds for Field-Grown Cotton and Evaluation of Canopy-Level Traits

Canopy 3D architecture is a critical determinant of light interception, photosynthetic efficiency, and final yield in cotton, yet its rapid and accurate characterisation remains challenging in field conditions. To achieve efficient, non-destructive, and quantitative monitoring of the canopy structure of field-grown cot...

Consistent Image Sequence Sampling from Single Image Diffusion Prior

This work proposes a novel training-sampling approach for single-image multi-scale diffusion models that enables consistent and joint sampling of image sequences and introduces a Laplacian-recomposition sampling algorithm to enforce multi-scale consistency.
