Interfaces based on projection screens have become increasingly
more popular in recent years, mainly due to the large screen size and resolution
that they provide, as well as their stereo-vision capabilities. This work shows a
local method for real-time detection of non-stationary photometric perturbations
in projected images by means of computer vision techniques. The method is
based on the computation of differences between the images in the projector’s
frame buffer and the corresponding images on the projection screen observed
by the camera. It is robust under spatial variations in the intensity of light
emitted by the projector on the projection surface and also robust under
stationary photometric perturbations caused by external factors. Moreover, we
describe the experiments carried out to show the reliability of the method. [-]
