Compressive Structured Light for Recovering Inhomogeneous Participating Media (2009)
Jinwei Gu, Shree Nayar, Eitan Grinspun, Peter Belhumeur, Ravi Ramamoorthi
Abstract. We propose a new method named compressive structured light for recovering inhomogeneous participating media. Whereas conventional structured light methods emit coded light patterns onto the...

Singular Points Analysis in Fingerprints Based on Topological Structure and Orientation Field (2009)
Jie Zhou, Jinwei Gu, David Zhang
Abstract. As an important feature of fingerprints, singular points (includingcores and deltas) not only represent the local ridge pattern characteristics, but also determine the topological structure...
Abstract Time-Varying Surface Appearance: Acquisition, Modeling and Rendering (2009)
For computer graphics rendering, we generally assume that the appearance of surfaces remains static over time. Yet, there are a number of natural processes that cause surface appearance to vary...
As an important feature of fingerprints, singular points ( core and delta) not only represent the local ridge pattern characteristics, but also determine the topological structure (i.e. fingerprint...
Chapter 14 GRAPHICAL REPRESENTATION OF FINGERPRINT IMAGES (2008)
Jie Zhou, David Zhang, Jinwei Gu, Nannan Wu
Abstract Fingerprint recognition is very important in automatic personal identification. In conventional fingerprint recognition algorithms, fingerprints are represented graphically with a simple set...

Biometrics Project: Bayesian Face Recognition (2008)
This project is to implement a 2D face recognition algorithm proposed in [2], which models the density of intrapersonal and extrapersonal face space separately with a single Gaussian for each, and...

Similarity-based online feature selection in content-based image retrieval (2006)
Wei Jiang, Student Member, Guihua Er, Qionghai Dai, Senior Member, Jinwei Gu, ...
Abstract—Content-based image retrieval (CBIR) has been more and more important in the last decade, and the gap between high-level semantic concepts and low-level visual features hinders further...
Fingerprint recognition by combining global structure and local cues (2006)
Jinwei Gu, Student Member, Jie Zhou, Senior Member, Chunyu Yang
Abstract—As an important feature, orientation field describes the global structure of fingerprints. It provides robust discriminatory information other than traditional widely-used minutiae points....
Radiometric calibration from a single image (2004)
Stephen Lin, Jinwei Gu, Shuntaro Yamazaki, Heung-yeung Shum
Photometric methods in computer vision require calibration of the camera’s radiometric response, and previous works have addressed this problem using multiple registered images captured under...
