This paper proposes an efficient intra-field deinterlacing algorithms using local adaptive rational interpolation filter (LARF). Experimental results show that the proposed algorithm provides satisfied performances in terms of both objective and subjective image qualities. What is more, it just exploits the local spatial gradient information among the neighboring pixels without complex preset-conditions...
In these days, video technology has successfully improved creating tremendous results. As video technologies improve, multimedia devices and demands from users are diversified. Therefore, the video codec used in these devices should support various displays with different resolutions. The technology to generate a higher resolution image from the associated low-resolution image is interpolation. The...
Video deinterlacing can be realized using time-space interpolation filters. To improve video deinterlacing quality with respect to missing pixels on moving diagonal lines, we developed a fuzzy concept that utilizes deinterlacing methods. The proposed algorithm consists of three parts. The first part is fuzzy rule-assisted edge-preserving-based deinterlacing (FED), which has an edge-preserving unit...
This paper describes the design and evaluation of a robust noise reduction fuzzy filter, and considers its application to video deinterlacing. The proposed fuzzy filter is designed to reduce mixed noise (random and impulse) and to be used in real-time deinterlacing. The proposed algorithm consists of two main processes: an adaptive weighted fuzzy filter and an edge direction based deinterlacer. The...
