This paper deals with self-calibration and its adaptation to structured light vision. A brief survey on selfcalibration for stereovision is first proposed. Then, after having described the geometry of a structured light sensor and the constraints it imposes, a method based on the generation of Euclidean constraints is detailed. It is mainly shown how the projection of a known pattern is used to...

With the aim of providing our structured light sensor with adaptive capabilities, an uncalibrated reconstruction method is presented here. It allows us to simultaneously determine the projection matrices and the co-ordinates of 3-D points in a projective frame by only using pixel correspondences. Then, by translating geometrical knowledge about the scene into mathematical constraints, an Euclid...

CONTEXT: Systematic literature reviews largely rely upon using the titles and abstracts of primary studies as the basis for determining their relevance. However, our experience indicates that the abstracts for software engineering papers are frequently of such poor quality they cannot be used to determine the relevance of papers. Both medicine and psychology recommend the use of structured abst...

Reflection transformation imaging offers a powerful new method of documenting and communicating numismatic cultural heritage information. The challenges of documenting numismatic material will be examined along with the limitations of traditional documentary techniques. Previous uses of structured light scanning and PTMs in numismatic documentation are reviewed and evaluated. A novel, low cost ...

background and purpose: biochemistry is extremely difficult in preclinical medical education because of the monotonous use of lectures, tutorials, practical and end of semester load with end of semester examination. although several studies have been carried out on learning biochemistry in europe and america, asian studies are very few and literature in the sri lankan context is lacking. we aim...

objective: in aug 2004, for the first time, a psychiatric osce was piloted in iran. the objective of current study was to explore the view and opinion of both candidates and examiners after they took part in the exam. method: two focus groups were formed. there were 10 participants in each group. each group was asked to discuss the advantages and disadvantages of the osce. the discussion was ta...
