Research Interest

If multiple projectors are used to generate a mosaic image there are two type of problems which need to be addressed. These are geometric correction and photometric correction. Photometric correction is related to change in the brightness and color changes among the projectors and in the regions where the projectors overlap. In this project the focus is on developing techniques which would efficiently provide a pleasing perceptual experience to the user related to change in intensity and color variation among projectors while modifying the overlap region in such a manner that it apperas seamless.
