3D Iterative Spatiotemporal Filtering for Classification of Multitemporal Satellite Data Sets
Hessah Albanwan, Rongjun Qin, Xiaohu Lu +3
The current practice in land cover/land use change analysis relies heavily on the individually classified maps of the multitemporal data set. Due to varying acquisition conditions…
Using Orthophoto for Building Boundary Sharpening in the Digital Surface Model
Xiaohu Lu, Rongjun Qin, Xu Huang
Nowadays dense stereo matching has become one of the dominant tools in 3D reconstruction of urban regions for its low cost and high flexibility in generating dense 3D points. Howev…
A Comparison of Stereo-Matching Cost between Convolutional Neural Network and Census for Satellite Images
Bihe Chen, Rongjun Qin, Xu Huang +2
Stereo dense image matching can be categorized to low-level feature based matching and deep feature based matching according to their matching cost metrics. Census has been proofed…
Fast 3D Line Segment Detection From Unorganized Point Cloud
Xiaohu Lu, Yahui Liu, Kai Li
This paper presents a very simple but efficient algorithm for 3D line segment detection from large scale unorganized point cloud. Unlike traditional methods which usually extract 3…
Learning to Refine Object Contours with a Top-Down Fully Convolutional Encoder-Decoder Network
Yahui Liu, Jian Yao, Li Li +2
We develop a novel deep contour detection algorithm with a top-down fully convolutional encoder-decoder network. Our proposed method, named TD-CEDN, solves two important issues in…
