A novel, real-time and robust occupancy extraction system is going to be presented in this paper. The main contribution of the paper is to introduce a novel camera calibration algorithm to a multi-space area. The proposed calibration method is accurate, efficient and free of any error propagation among cameras' calibrations, without usage of overlapping(More)
This letter presents a novel framework for gait recognition augmented with soft biometric information. Geometric gait analysis is based on Radon transforms and on gait energy images. User height and stride length information is extracted and utilized in a probabilistic framework for the detection of soft biometric features of substantial discrimination(More)
This paper presents a novel framework for the automatic recognition of Activities of Daily Living (ADLs), such as cooking, eating , dishwashing and watching TV, based on depth video processing and Hidden Conditional Random Fields (HCRFs). Depth video is provided by low-cost RGB-D sensors unobtrusively installed in the house. The user's location, posture, as(More)
Virtual User Models (VUMs) can be a valuable tool for accessibility and ergonomic evaluation of designs in simulation environments. As increasing the accessibility of a design is usually translated into additional costs and increased development time, the need for specifying the percentage of population for which the design will be accessible is crucial.(More)
A novel big data building performance evaluation knowledge processing and mining system utilizing visual analytics is going to be presented in this paper. A large dataset comprised of building information, energy consumption, environmental measurements, human presence and behavior and business processes is going to be exploited for the building performance(More)
In this paper, we present a novel methodology to evaluate the accessibility of products using virtual prototypes. The novelty is that the product evaluation is based on simulating the interactions of users with physical deficiencies in virtual and immersive environments. Virtual users with special needs, e.g. elderly or impaired people, were modelled using(More)
