Machine Learning for Human Data Modelling and Analysis
Taking advantage of the recent advancement in machine learning and the availability of big data, computers have become smarter than ever in understanding complicated data. In this talk, I will focus on the modelling and analysis of human data, which can be represented in formats such as images, video, 3D movement and surfaces. Such data is core to a wide spectrum of research fields including computer vision (e.g. action recognition, pose estimation, 3D reconstruction), computer graphics (e.g. character animation, crowd simulations) and biomedical engineering (e.g. diseases diagnosis, motion analysis). Modelling human data effectively is a challenging problem as it is high dimensional in nature and diverse in representations. I will talk about how machine learning techniques can be used to take on the challenge to come up with novel models that enable robust applications. In particular, I will discuss how state-of-the-art deep learning provides a powerful framework for large-scale human data modelling and analysis. Finally, I will share some insights into future research opportunities and interesting research directions in this area.

Machine Learning for remote sensing image analysis
In this talk, he will describe the state of the art on the development and application of machine learning methodologies in the remote sensing domain. He will also describe the specific remote sensing analysis problems that are typically handled by machine learning. On important type of sensor is the hyperspectral image sensor. Hyperspectral image sensors have been important tools for the characterization of materials based on their light reflectance mainly in remote sensing but in other domains as well. Hyperspectral images contain many spectral bands, each revealing the earth surface reflected light at a particular wavelength. These hyperspectral images require specific image processing and analysis methodologies. In this talk, an overview will be given of recent developments of machine learning in hyperspectral image analysis. Some of the strategies that are elaborated on are kernel methods, neural network methods, manifold learning methods, structured output methods, ensemble learning methods and sparse learning methods.

Deep Hierarchies in Human and Computer Vision
Computer vision – although being still a rather young scientific discipline – in the last decades was able to provide some impressive examples of artificial vision systems that outperform humans. However, the human visual system is still superior to any artificial vision system in visual tasks requiring generalization and reasoning (often also called ‘cognitive vision’) such as extraction of visual based affordances or visual tasks in the context of tool use and dexterous manipulation of unknown objects.
Two decades ago, there has been a strong connection between the two communities dealing with human vision research and computer vision. This link however has been somehow lost recently and computer vision has been more and more developed into a sub-field of machine learning. In this talk, I argue that the reason for the superiority of human vision for ‘cognitive vision tasks’ is connected to the deep hierarchical architecture of the primate’s visual system.
The talk is divided into two parts: First, I will give an overview about today’s knowledge about the primate’s (and by that the human’s) visual system primarily based on neurophysiological research. This part is based on the paper (Kruger et al. 2013, IEEE PAMI) and is in particular addressing computer vision and machine learning scientists as audience.
In the second part of the talk, I will describe a three level hierarchical cognitive robot system in which actions are learned by observing humans performing these actions (Kruger et al. 2013, KI). Learning is taking place at the different levels of the hierarchy in rather different representations. On the sensory-motor level, the shape and appearance of objects as well as optimal action trajectories and force torque profiles are represented. On the mid-level, a discrete visual representation based on semantic event chains (Aksoy et al. 2011) bridges towards the planning level, the highest representational level. I will describe different the learning problems on the different representational levels and their interaction.

Monocular 3D detection of rigid and non-rigid shapes
In this talk, I will first present an approach to the PnP problem, the estimation of the pose of a calibrated camera from n point correspondences between an image and a 3D model of a rigid object, whose computational complexity grows linearly with n. Our central idea is to express the 3D points as a weighted sum of four virtual control points. The problem then reduces to estimating the coordinates of these control points in the camera coordinate system, which can be done in O(n) using simple linearization techniques. I will then show how an algebraic outlier rejection scheme can be introduced within the computation of the pose, without the need to resort to RANSAC-based strategies.
In the second part of the talk I will show how the same linear formulations can be extended to retrieving the shape of 3D deformable objects. However, since monocular non-rigid reconstruction is severely under-constrained we will have to consider additional constraints, either based on local rigidity (to reconstruct deformable and inextensible surfaces), or based on shading coherence (to reconstruct deformable and stretchable surfaces). Finally I will discuss the major limitations of these linear formulations and propose a novel and alternative stochastic exploration strategy. I will present results both for non-rigid shape and human pose recovery.

Indoor Navigation Infrastructure based on Augmented Reality Techniques
Indoor navigation systems have represented a hot research topic for the research community with many different proposals to position people and keep track of their movements. In this lecture, Dr. Morcillo will take a step forward describing an object-oriented distributed architecture for highly scalable indoor navigation systems. The idea behind this architecture is to assist people with different needs while they stay in large spaces or buildings, such as public administration buildings, transport facilities, hospitals and so on, helping them reach their goals in such environments.
In this context, the use of Augmented Reality techniques boosts the concept of mobility thanks to the underlying architecture, integrating heterogeneous hardware devices and tracking methods. The resulting platform is a multi-layered scalable architecture based on autonomous agents. The most relevant work carried out by the Applied Artificial Intelligence Research Group at the University of Castilla-La Mancha will be also discussed.

Reality Mining for Real: Large-Scale Human Behavior and Smartphone Data
The large-scale understanding of personal and social behavior from smartphone sensor data is an emerging trend in computing. Smartphones can constantly sense human location, motion, proximity, and communication, and represent one of the most accurate means of tracing human activities. All this data,as never before, is being generated at massive scales.
I will present an overview of recent work in my research group in this domain, which is addressing mobile sensing, data analysis, and applications. I will first describe our experience with the collection of a rich corpus of real life data using smartphones as sensors, and discuss a few of the many associated challenges – both human and technological. I will then present computational methods that we have developed to discover a variety of patterns, including daily routines of individuals, trends of phone application usage, social interaction types, and personality traits. I will finally discuss about open issues in this domain.

Multiple Motion Segmentation based on Spatio-temporal Volume Recognition. Application to Optical flow estimation
In this lecture, a new methodology for extracting motion patterns is applied to optical flow estimation in the presence of multiple motions. The proposed approximation deals with the problem in two stages. In the first one, the most important motions are segmented; in the second one, the optical flow is estimated on the basis of the motions detected in the previous stage. To extract relevant motions, a new approach based on a spatio-temporal filtering is presented. The approach groups together parts of a moving object that have been separated into various filter responses because of the object’s spatial structure, thereby avoiding the spatial dependency problem associated with a representation based on spatio-temporal filters. The proposed model, therefore, generates one “motion pattern” for each motion detected in the sequence. To obtain an optical flow estimation, which is able to represent multiple velocities, the gradient constraint is applied to the output of each filter so that multiple estimations of the velocity at the same location may be obtained. For each “motion pattern” detected in the previous stage, the velocities at a given point corresponding to the same motion are then combined using a probabilistic approach. In the application to optical flow estimation, the use of “motion patterns” allows multiple velocities to be represented, while the combination of estimations fromdifferent filters helps reduce the aperture problem. This technique is illustrated on real and simulated data sets, including sequences with occlusion and transparencies.
