چکیده

This paper presents an algorithm for video de-interlacing. The approach uses three fuzzy logic-based systems to adapt the interpolation strategy to the presence of motion and edges. Furthermore, the algorithm is able to deal with any kind of TV material independently of the source used to acquire the scene. Extensive simulations of standard and real sequences prove the efficiency of the proposed algorithm.

Evaluation of Several Operators for Fuzzy-based Motion Adaptive De-interlacing

Video signals can be interlaced or noninterlaced. The interlaced scan format suffers from several possible artifacts such as flicker, twitter, and crawling. De-interlacing algorithms convert an interlaced video signal to the progressive scan format by interpolating the missing lines. These algorithms can be used to improve picture quality, but can also be necessary to use interlaced video on pr...

Spatio - Temporal Adaptive Interlaced

In this paper, we propose two adaptive interlaced-to-progressive conversion techniques in which the adequacy of the estimated motion vector is evaluated. If the motion vector is unlikely to give a good temporal motion compensated interpolation result, spatial interpolation is favored or selected to avoid temporal artifacts. In the rst proposed interlaced-to-progressive conversion technique, cal...

Progressive scan conversion based on edge-dependent interpolation using fuzzy logic

De-interlacing algorithms realize the interlaced to progressive conversion required in many applications. The most cost efficient are intra-field techniques, which interpolate pixels of the same field. Some of these methods use the upper and lower line pixels. Among them, the ELA algorithm is widely employed since it reconstructs the edges of the de-interlaced image with more accuracy eliminati...
