A shared interactive smart table based on camera-projector systems
Young‐Ho Suh, Kang‐Woo Lee, Sang Keun Rhee · 2016
One of the key challenges of remote sharing systems based on camera-projector pairs is the visual echo problem. However, existing visual echo cancellation schemes are either too theoretical or hardware-dependent to deploy for common use in arbitrary systems. Therefore, we present a simple and practical visual echo cancellation scheme. Experimental results shows that our system exhibits performance no less than 10 fps on exchanging non-echo images of 640 × 480 size in a full-duplex mode.
