In this paper, we present a new framework to automatically group similar shots into one scene, where a scene is generally referred to as a group of shots taken place in the same site. Two major...
Camera Breaks Detection by Partitioning of 2D Spatio-temporal Images in MPEG Domain (2007)
C. W. Ngo, T. C. Pong, R. T. Chin
In this paper, we propose a new approach to detect camera cuts and wipes. The approach projects a video into two images representing the spatio-temporal continuity of a video life. Visually, these...
Detection of Gradual Transitions through Temporal Slice Analysis (1999)
C. W. Ngo, T. C. Pong, R. T. Chin
In this paper, we present approaches for detecting camera cuts, wipes and dissolves based on the analysis of spatio-temporal slices obtained from videos. These slices are composed of spatially and...
Exploiting Image Indexing Techniques in DCT domain (1998)
C. W. Ngo, T. C. Pong, R. T. Chin
Abstract. This paper is concerned with the indexing and retrieval of images based on features extracted directly from JPEG discrete cosine transform (DCT) domain. We examine possible ways of...
A Survey of Video Parsing and Image Indexing Techniques in Compressed Domain (1998)
C. W. Ngo, T. C. Pong, R. T. Chin
With the wide spread use of WWW, digital libraries are expected to handle more visual information in the future. Furthermore, most of the data are represented in compressed formats due to the...
