Variational Motion Compensated Deinterlacing
In this paper we present a novel motion compensated deinterlacing scheme based on a joint variational framework of motion estimation and creation of new pixel values. We propose a specific energy formulation for that purpose, optimized by solving corresponding EulerLagrange equations. The difficult issue of calculating motion on interlaced image sequences is addressed and the presented algorith...
متن کاملVideo Upscaling Using Variational Methods
In this thesis we do image sequence upscaling using variational methods. We have developed, implemented and tested the three main elements of the upscaling part of a video processor using variational methods plus a non-variational preprocessing method detecting the scan format of the input video. The three upscalings needed are deinterlacing (DI), which is creating the never recorded every othe...
متن کاملSpatiotemporal video deinterlacing using control grid interpolation
With the advent of progressive format display and broadcast technologies, video deinterlacing has become an important video processing technique. Numerous approaches exist in literature to accomplish deinterlacing. While most earlier methods were simple linear filtering-based approaches, the emergence of faster computing technologies and even dedicated video processing hardware in display units...
متن کاملHigh-Definition Video Deinterlacing Using FPGAs
Deinterlacing was developed to address a legacy problem: the interlaced video that was required by old analog televisions must be converted to be shown on today’s digital televisions. An interlaced video is a succession of 50/60 fields per second, where each field carries only half of the rows that are displayed in each frame of video. In some ways, interlaced video was an elementary compressio...
متن کاملImprovement of Conventional Deinterlacing Methods with Extrema Detection and Interpolation
This article presents a new algorithm for spatial deinterlacing that could easily be integrated in a more complete deinterlacing system, typically a spatio-temporal motion adaptive one. The spatial interpolation part often fails to reconstruct close to horizontal lines with a proper continuity, leading to highly visible artifacts. Our system preserves the structure continuity taking into accoun...
