Accession number: 14182785 Title: Depth from defocus based on geometric constraints Authors: Qiufeng Wu1; Kuanquan Wang1 ; Wangmeng Zuo1 Author affiliation: 1 Sch. of Comput. Sci. & Technol., Harbin Inst. of Technol., Harbin, China Source title: Journal of Computers Abbreviated source title: J. Comput. (Finland) Volume: 9 Issue: 1 Publication date: Jan. 2014 Pages: 44-51 Language: English ISSN: 1796-203X Document type: Journal article (JA) Publisher: Academy Publisher Country of publication: Finland Material Identity Number: DW39-2014-005 Abstract: This paper proposes a Depth from Defocus (DFD) model based on geometric constraints. The two measured defocused images match with each other with this method including geometric constraints, which bypasses estimation of the radiance. These geometric constraints vary with different relative position of image plane and image focus. The experimental results on the synthetic and real images show that this method is accurate and efficient. The experimental results on the synthetic images with noise show that this method is robust to the images with Salt &Pepper and Poisson noise.
