Title: Texture Generation with Perceptual Feature Learning

Abstract: This talk introduces a novel task of generating texture images based on perceptual feature learning. Although in the past procedural models and even commercial packages were commonly used for creating textures, texture generation from user-defined perceptual attributes or semantic descriptions has been rarely studied. Perceptual attributes, such as directionality, regularity, roughness together with semantic descriptions are important factors for human observers to describe a texture. Thus, the first question is how to learn these perceptual features; several methods including on both hand-crafted and deep learning features are introduced. Then we present a framework based on joint deep neural networks that combines adversarial training and perceptual feature regression for texture generation, while only random noise and user-defined perceptual attributes are required as input. In this framework, a preliminary trained convolutional neural network is essentially integrated with the adversarial framework, which can drive the generated textures to possess given perceptual attributes. An important aspect of the proposed model is that, if we change one of the input perceptual features, the corresponding appearance of the generated textures will also be changed. We designed several experiments to validate the effectiveness of the proposed method. The results show that the proposed method can produce high quality texture images with desired perceptual properties. Demonstrations based on mobile applications and virtual reality are also provided.

Title: Binary relevance for multi-label learning

Abstract: In recent years, multi-label learning has become one of the important research topics in machine learning community. Binary relevance (BR) is arguably the most popular approach towards multi-label learning, which decomposes the multi-label learning problem into a number of independent binary classification problems, one per category. In view of the well-known weakness of BR, i.e. ignorance of label correlations, a number of enhanced versions of BR have been developed in recent years by endowing BR with the ability of label correlations exploitation. Nonetheless, in addition to label correlations exploitation, there are several factors which need to be considered to make BR-based approach work effectively. In this talk, I will introduce some of our recent progresses on BR-based multi-label learning.In recent years, multi-label learning has become one of the important research topics in machine learning community.

Title: Consensus learning

Abstract: Combining multiple models into one consensus model helps among others reduce the uncertainty in the initial models. Consensus learning can be formulated in arbitrary problem domains, either in an informal or a formal manner. In this talk the focus will be given to the formal framework of so-called generalized median computation. The concept of this framework and related computation algorithms will be presented. A variety of applications in pattern recognition will be shown to demonstrate the power of consensus learning.

Title: On BigData, Object Recognition and Medical Imaging

Abstract: Object recognition performance near to the human visual systems (HSV) is a long lasting research goal. Is it bigdata, massive processing or deeper semantics that will win the challenge? Or maybe something in-between? In this keynote we review some works and results in recognition and classification of medical and food images. We also review bigdata capabilities and technologies, and some keypoints from deep learning. Then we go back to the grand challenge of object recognition and preview our own present and future work on the subject.

Title: Data-driving Pattern recognition: from Subspace Approach and Sparse Coding to Deep Learning

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.

Title: Recent Advances in Face and Body Biometrics

Abstract: Nowadays, biometric systems can achieve satisfactory performance in many applications, especially in controlled scenarios. When it comes to less controlled scenarios, these systems are affected by plenty of different variability sources that greatly hinder their performance. In the particular case of face recognition, these variability sources are related to changes in pose, illumination, expression, occlusions, distance to the camera, low resolution, and so forth. This talk is focused on the search of additional identity clues to enhance the performance of biometric systems. In the context of unconstrained scenarios where the main biometric trait is the face, researchers have shown recently the benefits in person recognition that can be obtained by combining biometrics with other kinds of soft biometric data, like gender, or some kind of silhouette information. Finally, motivated by the fact that faces and bodies are equally salient and available in unconstrained scenarios at a distance, we will discuss the combined used of face and body-based biometrics, in practical scenarios for person identification and gender recognition.

Title: Applying computer vision in wearable computer and virtual reality systems

Abstract: In this talk I will discuss various projects carried out in the Chinese University of Hong Kong (CUHK) on computer vision and machine learning. First, I will talk about research of developing an instant language assistant in a form of a wearable computer that can help users to translate foreign printed words. When the user is pointing to the word using his/her finger, the system will read out the word and translate its meaning instantly. I will also discuss a system that uses a robust ARUCO marker for applications in virtual reality. Since machine learning has shown to be very promising in many pattern recognition applications, we have conducted research using neural networks for edge detection, object tracking, and pose estimation. Theories together practical issues encountered in these research projects will be elaborated in the talk.

Title: Behavioral Biometrics based on Human-Device Interaction

Abstract: Behavioral biometrics emerge as a feasible way to model human interaction with electronic devices (smartphones, computers, tablets). Behavioral patterns can be used to statistical modelling users in terms of identity, age, and actions by means of existing sensors (mouse, keypad, touch screen…). Main advantages of behavioral biometrics are the transparent modelling and continuous authentication. Some of the main drawbacks are the high intra-class variability, short utterances and limited performance. This keynote will survey some of the most promising behavioral biometrics including its main challenges, applications and research opportunities.
