Title:
Nipple Detection and Localization in Automated Whole Breast Ultrasound (AWBUS) Images
Abstract:
Breast cancer causes massive deaths every year and early screening can lower the mortality rates significantly. Among various techniques, Ultrasound Imaging is the most preferred choice for early breast cancer diagnosis. The nipple is an important landmark, normally used as a reference point to precisely locate and document the tumor location on BUS images. The talk concentrates on the automatic segmentation of the Nipple area using (a) A Modified U-Net architecture and (b) Ensemble Learning technique consisting of shape and texture features. The performance of the models have been tested on our own dataset obtained from the Shantou First Affiliated Hospital, provided high F scores illustrating good prospect in clinical diagnosis.

Title:
Digital Image Steganography Using Error Correcting Code
Abstract:
Steganography is the art and science of embedding secret messages in such a way that no one, except the sender and the intended receiver, can be made aware of the existence of the hidden message. Steganographic techniques overcome the traditional cryptographic approach, providing new solutions for secure data transmission without raising users’ malicious intention. This talk introduces error correcting code (ECC) based data hiding (DH) on digital image, which may have wide and practical applications in modern digital environment. The matrix coding (using ECC) based DH was first proposed by Crandall to improve embedding efficiency and meanwhile reduce the number of changed bits. Many ECC-based DH schemes were accordingly proposed, e.g., using Hamming code, BCH code, and Golay code. This talk briefly describes some DH schemes using Hamming+1, Hamming-like, Golay+1, Golay+2, and unequal error protection (UEP) codes. Moreover, a new notion of Hamming+k scheme and its variants will be introduced. When considering ECC based DH on pixel domain, the ECC based approach has tight relationship between the well-known data hiding technologies LSB and OPAB. In fact, these three approaches are different ways to change bits for embedding secret data. Thus, combining them carefully may trade embedding capacity and the number of changes. In addition, this lecture also includes how to apply ECC based DH on non-pixel, e.g., frequency domain and compressed domain.
Bio:
Professor Ching-Nung Yang obtained his Ph. D. degree in Electrical Engineering from National Cheng Kung University. His B.S. and M.S. degrees, both were awarded in Department of Telecommunication Engineering from National Chiao Tung University. Dr. Yang served in National Dong Hwa University since 1999. His current title is Professor in Department of Computer Science and Information Engineering. He had been Visiting Professor to University of Missouri Kansas City, University of Milan, and University of Tokyo. He is currently a Fellow of IET (IEE) and an IEEE senior member. Professor Yang has done extensive researches on visual cryptography and secret image sharing, and is the chief scientist in both areas. In fact, a very important innovation of visual cryptography, the probabilistic visual cryptography, was firstly proposed by Professor Yang. His areas of interest include error correcting code, multimedia security, cryptography, and information security. He has authored two books and has published over 250 professional research papers (including more than 110 SCI-indexed journal papers) in the areas of information security and coding theory. In the meantime, he has served/is serving in international academic organizations. He serves as technical reviewers for over 40 major scientific journals in the areas of his expertise, and serves as editorial boards and editors of special issues for some journals. Also, he was invited as chairs, keynote speakers, and members of program committees for various international conferences. He is the recipient of the 2000, 2006, 2010, 2012, and 2014 Fine Advising Award in the Thesis of Master/PhD of Science awarded by Institute of Information & Computer Machinery.
