We propose a simple non-linear content-adaptive filter that is efficient in removing noise from a video. The proposed filter is called spatiotemporal varying filter (STVF) and is able to produce optimal results in the sense that it minimizes the weig

In video indexing and segmentation, scene change detection is an essential step. However, the problems of inaccuracy and high complexity for existing scene change detection methods are still unsolved. This work presents several advance methods using

In this paper, we proposed a spatial-temporal de-interlacing algorithm for conversion of interlaced video to progressive video. Our proposed algorithm estimates the motion trajectory of three consecutive fields interpolates the missing field along th

In this paper, we propose a multiple objective frame rate up conversion algorithm (MOFRUC), which utilizes two different models. The first model is a constant velocity model that assumes the objects position is a linear function of time. The second m

Key frame selection is the process to select the most representative frames of a long video sequence based on a given set of rules. This paper presents a novel algorithm for selecting a set of representative frames in MPEG compressed video. We use a

In this paper, we proposed a partitioned linear minimum mean square error estimator (P-LMMSE) for error concealment. The proposed P-LMMSE estimator adopts the multi-hypothesis motion compensation (MHMC) technique to reconstruct the corrupted block, i

We propose a content-adaptive interpolation algorithm for digital images. The proposed algorithm makes use of a non-linear spatial varying filter (SVF), which is simple but efficient in enlarging images. First, edge orientation statistics in an image
