Deinterlacing Algorithm Using Blackman-Harris Filter along the Piecewise Edge Direction

Joohyeok Kim and Jechang Jeong

Abstract—In this paper, we propose an improved deinterlacing algorithm which applies a filter along the edge directions. The existing deinterlacing algorithms do not take direction and rapidly changing pixels into account sufficiently and, in turn, it causes quality degradation. In order to improve image quality, we introduce piecewise-directional detection. It determines the direction between each line, which consists of nonlinear edge directions, in order to avoid the overshoot and undershoot. Also, we set the six filter coefficients using Blackman-Harris window to reconstruct a pixel to be interpolated. BH window mitigates the problem of truncated sinc functions that brings about Gibbs’ phenomenon due to the limited input signal. Simulation results show that the proposed algorithm is superior to the existing algorithms.

Index Terms—Deinterlacing, SINC interpolation, piecewise-direction.
