Current Research Interests:
Signal, Image, and Multimedia Processing, Learning Theory, Multimedia Computing and Communications
Dr. Cheng's research interests include image, multimedia, signal processing, pattern recognition and machine learning, and their applications to multimedia, biomedical computing and communications,and healthcare. He worked on multimedia information forensics, security, and pattern recognition. His current research focuses mainly on biomedical information and image processing.
Due to the extensive use of medical images for disease prevention, diagnosis and treatment, and health promotion in health care and biomedical research and practices, biomedical imaging and processing are becoming increasingly important. The research questions include how to fuse multiple image modalities and data sources to promote early diagnosis and improve the accuracy, how to represent and transmit huge amount of medical information, and how to extract the most salient information or obtain the sparse representations from large data set, etc. He studies these issues by using machine learning, signal processing technics, etc.
