Embedded Video System-Based Motion-Adaptive De-Interlacing Algorithm

Abstract

An modified motion-adaptive de-interlacing algorithm was proposed in view of defects of traditional motion-adaptive de-interlacing algorithm in the aspects of motion detection and adaptive interpolation.Bipolar consecutive four fields was exploited to design criterion of motion state which improved the accuracy of the motion detection.Field insertion algorithm was exploited for interpolation of the static region which could increase vertical resolution of the image.Traditional ELA algorithm was modified by multi-directional edge detection for the interpolation of the motion region which could increase the function of horizontal edge detection and enhance the level of consistency edge direction estimation.Experimental results show that the proposed de-interlacing algorithm improves Peak Signal-to-Noise Ratio (PSNR) and restrains the artifacts such as saw-tooth,interline flicker,motion virtual image.
