This site is to show Hongwei Zhu's research/development works. He got Ph.D from the Environmental Remote Sensing Center, University of Wisconsin-Madison in December, 2012, with the thesis title "Reliable Automatic 3D Surface Extraction Incorporating Image Matching and Object Recognition". He also got a master degree from Computer Science Department of the same school in December, 2001. He also holds a master degree from Institue of Remote Sensing and GIS, Peking University; and his undergraduate major was Photogrammetry and Remote Sensing from Wuhan University (was Wuhan Technical Univeristy of Surveying and Mapping)
His interests are Digital Image Processing, Computer Vision, Database, Digital Photogrammetry and LiDAR. His current research/development focuses on 3D reconstruction from stereo image pair by automated Stereo Matching and Object Recognition.

Abstract: A stereo image matching algorithm based on feature points, multi-scale regions, areas, and recognized objects, such as buildings and roads was implemented. The algorithm includes several key parts: (1) Feature points extraction and reliable point matching; (2) Image segmentation and vectorization; (3) Object recognition/classification; (4) Matching using multi-scale regions, area, and recognized objects; (5) Bare earth surface reduction; (6) Manual editing of the automated matching result.
