Controlled Illumination for the Object Recognition with Projector Camera Feedback

In this paper a novel image capturing method for a solution of shading problem in computer vision is proposed. In the experiments, we performed the evaluation about the conditions of environment lighting and additional lighting and proposed controlled lighting method. Image-processing of self quotient image algorithm, histogram equalization, and luminance equalization were used for pre-processing to remove shading from a captured image for the comparative evaluation. Through the evaluation of robustness assumed appearance based method, the proposed method showed most stable results. In addition to this, the capability of the high dynamic range image reconstruction with approximation by using of projector camera system has been shown.
