Semantic Segmentation of Street View Images Using Graph Matching and Point Clouds
报告简介:
This talk presents a novel scene parsing approach via structure transferring on both images and point clouds. Unlike traditional methods that extract joint features from images and point clouds, we introduce a new framework which processes images and point clouds in separate pipelines and combine them in the inference step. We also propose a structure transfer scheme by finding maximal similar parts across scenes, which is realized via graph matching with a new model. The transferred structures, as well as the information from point clouds, are integrated in a new energy function to enhance the inference performance. Through integrating several additional terms, A multimedia approach to visualize and interact with large scale mobile LiDAR datathe energy function does not introduce any higher-order potentials, remaining a locally connected pairwise Markov Random Field (MRF), which can be efficiently optimized. We evaluate the approach on several challenging datasets, achieving promising performance.
