Local part chamfer matching for shape-based object detection
收藏 引用
PATTERN RECOGNITION 2017年 65卷 82-96页
作者: Yu, Qian Wei, Hui Yang, Chengzhuan Fudan Univ Sch Comp Sci Lab Cognit Model & Algorithm 825 Zhangheng Rd Shanghai 201203 Peoples R China Fudan Univ Shanghai Key Lab Data Sci Sch Comp Sci 825 Zhangheng Rd Shanghai 201203 Peoples R China
Chamfer matching is one of the elegant and powerful tools for shape-based detection in cluttered images. However, the chamfer matching methods, including oriented chamfer matching (OCM) and directional chamfer matchin... 详细信息

PATTERN RECOGNITION LETTERS 2016年 第Part3期83卷 243-250页
作者: Altinoklu, Burak Ulusoy, Ilkay Tari, Sibel Middle East Tech Univ Dept Elect & Elect Engn TR-06800 Ankara Turkey Middle East Tech Univ Dept Comp Engn TR-06800 Ankara Turkey
We present a Markov Random Field (MRF) based skeleton model for object shape and employ it in a probabilistic chamfer-matching framework for shape based object detection. Given an object category, shape hypotheses are... 详细信息

shape based detection and Top-Down Delineation Using Image Segments
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 2009年 第3期83卷 211-232页
作者: Gorelick, Lena Basri, Ronen Weizmann Inst Sci Dept Comp Sci & Appl Math IL-76100 Rehovot Israel Toyota Technol Inst Chicago IL 60637 USA
We introduce a segmentation-based detection and top-down figure-ground delineation algorithm. Unlike common methods which use appearance for detection, our method relies primarily on the shape of objects as is reflect... 详细信息
