Ensuring Color Consistency in RGB-D Multi-Camera Setup

Most multi-camera applications such as 3D volumetric teleconferencing assumes that each camera has a common and global lighting response. This assumption is not true as each individual camera usually exhibit radically different color responses. This leads to lesser quality of experience in 3D perception. To address this problem, we propose a simple but an efficient method to calibrate and correct color responses of multi-view cameras. The proposed method does not require the use of standard color calibration target, and only requires well lighted object or human in the scene.
