A Multi-layer MRF Model for Video Object Segmentation (2008)
Abstract. A novel video object segmentation method is proposed which aims at combining color and motion information. The model has a multilayer structure: Each feature has its own layer, called...
Color Image Classification and Parameter Estimation in a Markovian Framework (2008)
In this paper, we propose an unsupervised color image classification algorithm based on a Markov random field (MRF) model. In the MRF model, we use the CIE-luv color metric because it is close to...
c ○ World Scientific Publishing Company RECENT ADVANCES IN CONTENT-BASED VIDEO ANALYSIS (2008)
Chong-wah Ngo, Ting-chuen Pong, Hong-jiang Zhang
In this paper, we present major issues in video parsing, abstraction, retrieval and semantic analysis. We discuss the success, the difficulties and the expectations in these areas. In addition, we...
Chong-wah Ngo, Ting-chuen Pong, Hong-jiang Zhang, C. W. Ngo
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...
Zoltan Kato, Ting-chuen Pong, Song Guo Qiang
Herein, we propose a novel multi-layer Markov random field (MRF) image segmentation model which aims at combining color and texture features: Each feature is associated to a so called feature layer,...
Motion analysis and segmentation through spatio-temporal slices processing (2003)
Chong-wah Ngo, Ting-chuen Pong, Hong-jiang Zhang
This paper presents new approaches in characterizing and segmenting the content of video. These approaches are developed based upon the pattern analysis of spatio-temporal slices. While tradi-tional...

Abstract—This paper presents new approaches in characterizing and segmenting the content of video. These approaches are developed based upon the pattern analysis of spatio-temporal slices. While...
On clustering and retrieval of video shots through temporal slices analysis (2002)
Chong-wah Ngo, Ting-chuen Pong, Hong-jiang Zhang, Senior Member
Abstract—Based on the analysis of temporal slices, we propose novel approaches for clustering and retrieval of video shots. Temporal slices are a set of two–dimensional (2-D) images extracted...
A web-based course delivery system for online teaching and learning (2001)
Distance learning is commonly used as a means of providing education to learners at remote locations. In the past, this mode of education was common in continuing education and corporate training....
A Markov random field image segmentation model using combined color and texture features (2001)
Abstract. In this paper, we propose a Markov random field (MRF) image segmentation model which aims at combining color and texture features. The theoretical framework relies on Bayesian estimation...
Exploiting Image Indexing Techniques in DCT domain (1998)
Chong-wah Ngo, Ting-chuen Pong, T. Chin
This paper is concerned with the indexing and retrieval of images based on features extracted directly from the JPEG discrete cosine transform (DCT) domain. We examine possible ways of manipulating...
Kato, Zoltan, Pong, Ting-Chuen, Lee, John Chung-Mong
This paper deals with the classification of color video sequences using Markov Random Fields (MRF) taking into account motion information. The theoretical framework relies on Bayesian estimation...
