Matching multiple views

Image matching to relatively orient multiple views

This research was conducted together with graduate students,

JianQuan Zhang (1999) who wrote the master's thesis on this topic and got the MSc degree with the grade A+ and
Jian Zhong (2000), who continued the work in his master's thesis and got the MSC degree with the grade A.

Some resent results can be found in the paper

G. L. Gimel'farb and J.Zhong, "Matching Multiple Views by the Least Square Correlation"

presented at the 10^th International Workshop "Theoretical Foundations of Computer Vision" on Multi-Image Search, Filtering, Reasoning and Visualization, Schloss Dagstuhl/Wadern, Germany, March 12 - 17, 2000.

Below you will find experimental results in relative orientation of several pairs of the RADIUS model board images reduced to size of 83 × 65 pixels. In all these experiments the same window of size 61 × 51 pixels was centered to the central pixel (41, 32) of the prototype image, and the the least-square-correlation-based search has the goal to find the affine parameters transforming the second image to this prototype. The search grid of translations in the second image was centered to the same pixel (41,32). The final correlation value is denoted C, and the apparently wrong matches are given in red colour.
