Graduate Course Title: Computer Vision; Lecturer: Ge
Wang
Content: While image processing
techniques map images to images, computer vision methods map images to
descriptions. This course provides a basis
for research and development in the computer vision area. Introduction: Viewing
computer vision in the perspectives of computer science, bionics, and
philosophy; Pre-processing: Recovering 3D shape from image stereo pair, shading,
and texture; motion analysis; Segmentation: Boundary detection and region growing; Geometrical structures:
2D and 3D; Relational structures: Knowledge representation and use; Expert vision systems
Prerequisite: Digital picture processing,
artificial intelligence
Textbook: D. H. Ballard and C. M. Brown,
Computer Vision. Prentice-Hall, Englewood Cliffs, New Jersey, 1982

Wang G, Wei YR: A preliminary exploration on the
graduate course objective examination. Journal of Graduate School of
Academia Sinica 5(1):93-95, May 1988
Abstract: A method for the objective examination
design is developed for teaching of the graduate course "Digital
Picture Processing". In this method, questions are made to cover
the course material in a balanced manner, and the number of the
questions are determined according to an entropy-based criterion - the
uncertainty reducibility. It is concluded that the objective
examination method is accurate, reliable, cost-effective, and widely
applicable for teaching at the graduate level.

Wang G, Ding Y: English multiple-choice test
modeling and analysis. Journal of Mathematics in Practice and Theory
(Mathematics Association of China) 2:17-21, 1989
Abstract: English multiple-choice examinations
become increasingly popular in China. However, there exists a
substantial concern that such examinations are subject to randomness
and lack of reliability. In this paper, three probabilistic models are
constructed to characterize English multiple-choice questions in the
Test of English as a Foreign Language (TOEFL) administrated by
Educational Testing Service (ETS), USA. The relationship between the
examination score and the student's proficiency is quantified and
analyzed. According to the theoretical model, it is computed that the
standard deviation of the TOEFL score must be 13.96, very consistent to
the real value, which is 14 as reported by ETS. Our results help
understand the rationale/validity of the TOEFL and provide guidelines
for design of similar tests.
