Show-through Cancellation Method Using Kalman Filter Algorithm With Colored Driving Source in Duplex Scanning

抄録

Digital scanned image in duplex printing is often degraded by the show-through effect. This paper proposes the robust show-through cancellation method using the Kalman filter algorithm with the colored driving source. The linear mixture show-through image model of the proposed method is composed of the front and back sides image. The remarkable feature of the proposed method removes the show-through effect without sacrificing quality of the front-side image. Experimental results with real show-through images demonstrate the good performance visually of the proposed method.
