Speech Title: Embedding Important Information in Digital Images Using Magic Turtle Shells
Abstract: Steganography is the science of secret message delivery using cover media. A digital image is a flexible medium used to carry a secret message because the slight modification of a cover image is hard to distinguish by human eyes. In this talk, I will introduce some novel steganographic methods based on different magic matrices. Among them, one method that uses a turtle shell magic matrix to guide cover pixels' modification in order to imply secret data is the newest and the most interesting one. Experimental results demonstrated that this method, in comparison with previous related works, outperforms in both visual quality of the stego image and embedding capacity. In addition, I will introduce some future research issues that derived from the steganographic method based on the magic matrix.

Speech Title: Depth Image Based View Synthesis in 3D Video
Abstract: Several 3D video prototypes have been developed based on distinct techniques in 3D visualization, data format representation, and content production. Among them, depth-based 3D video has attracted research attention from both industry and academia, as it has been shown to be more efficient and flexible than stereoscopic 3D video or the conventional multi-view video, where virtual view rendering is a key technical procedure in the whole processing chain of a 3D video system. The talk will present a technical overview of depth-based 3D video system, with a focused discussion of our recent work on high quality view synthesis with depth-image-based rendering (DIBR) technique.

Speech Title: Generalized ELM-Deep Network Framework for Representation Learning
Abstract: Most of actual images such as human face images, industrial images and MRI images are high-dimensional data. The feature representation is mainly for the purpose of extracting useful information and of using this information to build non-supervised classifier/supervised classifier or other types of predictor because the image processing performance is often closely related to the feature data extracted and used. In this talk, we propose a generalized ELM-Deep learning framework which is intended to extract the optimized features. Then, we extend and apply this method for such application fields as dimension reduction, image identification, and image reconstruction, etc. Compared with other feature representation methods, the experimental results show that the generalization performance of the proposed generalized learning framework is very advantageous. A brief overview of other related research activities in the presenter's laboratory related to computer vision and machine learning is also provided. Applications have been extended towards intelligent transportation systems, surveillance and security, face and gesture recognition, vision-guided robotics, and bio-medical imaging, among others.

Speech Title: Vision and Image
Recognition: from Subspace Approach and Sparse Coding to
Abstract: Vision and image recognition handles high-dimensional data that contains rich information. Fully utilizing the rich information in image undoubtedly increases the possibilities of solving difficult real world problems such as identifying people, object and understanding the behavior of people, objects and crowds. This, however, brings the difficulty for us to design a robust recognition system due to the complex characteristics of image and large variations of images taken under different conditions. Machine learning from the training database is a solution to extract effective features from the high dimensional image for classification. It is thus not a surprise that approaches of the learning-based methods emerge in various research journals and conferences. This speech reviews various research efforts and technologies developed in solving difficult real world vision and image recognition problems. The first attempt is subspace approaches that extract features or reduce the data dimensionality. The speech will be far more than just PCA and LDA. The sparse representation-based classifier (SRC) significantly differentiates itself from the other classifiers in three aspects. One is the utilization of training samples of all classes collaboratively to represent the query images and another is the sparse representation code that coincides with the general classification target. The last is the L1-norm minimization of the representation error that enables SRC to recognize query images heavily corrupted by outlier pixels and occlusions. The analysis of these three merits of SRC pave the way for us to investigate how the recent developments solve these problems and overcome the limitations of SRC, which bring the sparse representation-based image classification to a significantly higher level. Finally, deep learning in vision and image recognition, CNN, is explored and its merits and limitations are investigated.

Seech Title: Development of small-sized pixel structures for high-resolution CMOS image sensors
Abstract: We present our studies on small-sized pixel structures for high-resolution CMOS image sensors. To minimize the number of pixel components, single-transistor pixel and 2T pixel architecture were proposed. To deal with crosstalk between pixels, MOS capacitor deep trench isolation (CDTI) was integrated. CDTI-integrated pixel allows better achievements in dark current and full-well capacity in comparison with the configuration integrating oxide-filled deep trench isolation (DTI). To improve quantum efficiency (QE) and minimize optical crosstalk, back-side illumination (BSI) was developed. Also, vertical photodiode was proposed to maximize its charge-collection region. To take advantages of these structures/technologies, we developed two pixel options (P-type and N-type) combining CDTI or DTI, BSI and vertical photodiode. All the presented pixel structures were designed in 1.4µm-pitch sensor arrays, fabricated and tested.

Seech Title: Researches in Visual Cryptography
Abstract: Visual cryptography is developed based on the need of information sharing. A secret is partitioned into n shadow images (shares), and each participant receives only one share. Once any k or more shares of a secret are stacked together, the secret image will be visually retrieved without the help of the computer. The secret image will be invisible if the number of stacked shares is less than k. This speech introduces our studies in extending the capabilities of visual cryptography for handling gray-level and color images. Besides of information hiding, applications of visual cryptography have been extended towards steganography, watermarking and progressive revealing, among others.
