Topologically Consistent Agricultural Parcel Vectorization with Semantic-Guided Diffusion and Topology-Aware Polygonization
Weiqin Jiao, Xiaolong Zuo, Claudio Persello
Agricultural parcel polygons play a fundamental role in geospatial applications such as precision agriculture, land administration, and crop monitoring. Beyond regular polygon geom…
ACPV-Net: All-Class Polygonal Vectorization for Seamless Vector Map Generation from Aerial Imagery
Weiqin Jiao, Hao Cheng, George Vosselman +1
We tackle the problem of generating a complete vector map representation from aerial imagery in a single run: producing polygons for all land-cover classes with shared boundaries a…
CAGE: Continuity-Aware edGE Network Unlocks Robust Floorplan Reconstruction
Yiyi Liu, Chunyang Liu, Bohan Wang +6
We present CAGE (Continuity-Aware edGE) network, a robust framework for reconstructing vector floorplans directly from point-cloud density maps. Traditional corner-based polygon re…
T-Graph: Enhancing Sparse-view Camera Pose Estimation by Pairwise Translation Graph
Qingyu Xian, Weiqin Jiao, Hao Cheng +2
Sparse-view camera pose estimation, which aims to estimate the 6-Degree-of-Freedom (6-DoF) poses from a limited number of images captured from different viewpoints, is a fundamenta…
LDPoly: Latent Diffusion for Polygonal Road Outline Extraction in Large-Scale Topographic Mapping
Weiqin Jiao, Hao Cheng, George Vosselman +1
Polygonal road outline extraction from high-resolution aerial images is an important task in large-scale topographic mapping, where roads are represented as vectorized polygons, ca…
RoIPoly: Vectorized Building Outline Extraction Using Vertex and Logit Embeddings
Weiqin Jiao, Hao Cheng, Claudio Persello +1
Polygonal building outlines are crucial for geographic and cartographic applications. The existing approaches for outline extraction from aerial or satellite imagery are typically…
PolyR-CNN: R-CNN for end-to-end polygonal building outline extraction
Weiqin Jiao, Claudio Persello, George Vosselman
Polygonal building outline extraction has been a research focus in recent years. Most existing methods have addressed this challenging task by decomposing it into several subtasks…
