Elimination of Keystone and Crosstalk Effects in Stereoscopic Video Elimination of Keystone and Crosstalk Effects in Stereoscopic Video

Rapport technique de l'INRS-T el ecommunications no. 95-31 Summary First of all, I would like to thank all the people who made this internship possible. Mr Gille Delisle, headmaster of the INRS-T el ecommunications, Mr Janusz Konrad, in charge of my study, and Mr Henri Maitre, head of the Image option in the ENST. I a l s o w ould like to thank all the students, professors and associates for their kindness and support. Finally, I thank all the Quebecers I met during this internship in Montreal because of their true friendship. The aim of this internship was to study stereoscopic video, that is three dimensional television, rst become familiar with this technology, and then improve t h e quality of the images. Two major defects were analysed during these ve months. The keystone distortion, which is a geometric defect, and the crosstalk distortion coming from the technological limitations of display systems. This internship was all the more interesting as many laboratories troughout the world are studying three-dimensional advanced technologies, which m i g h t become a new standard in term of image viewing and broadcasting in the next century.
