Tangible bits: towards seamless interfaces between people, bits and atoms
- Proceedings of the SIGCHI conference on Human factors in computing systems, ACM Press: 234--241
, 1997
"... This paper presents our vision of Human Computer Interaction (HCI): "Tangible Bits. " Tangible Bits allows users to "grasp & manipulate " bits in the center of users’ attention by coupling the bits with everyday physical objects and architectural surfaces. Tangible Bits also ..."

as the foreground and background of human activities. This paper describes three key concepts of Tangible Bits: interactive surfaces; the coupling of bits with graspable physical objects; and ambient media for background awareness. We illustrate these concepts with three prototype systems – the metaDESK, trans
K-SVD: An Algorithm for Designing Overcomplete Dictionaries for Sparse Representation
, 2006
"... In recent years there has been a growing interest in the study of sparse representation of signals. Using an overcomplete dictionary that contains prototype signal-atoms, signals are described by sparse linear combinations of these atoms. Applications that use sparse representation are many and inc ..."

Sorting Atomic Activities for Discovering Spatio-temporal
- Patterns in Dynamic Scenes”, Int. Conf. on Image Analysis and Processing (ICIAP
, 2011
"... Abstract. We present a novel non-object centric approach for discovering ac-tivity patterns in dynamic scenes. We build on previous works on video scene understanding. We first compute simple visual cues and individuate elementary activities. Then we divide the video into clips, compute clip histogr ..."

improvements with respect to previ-ous works: (i) we consider a variant of EMD with a robust ground distance, (ii) clips are represented with circular histograms and an optimal bin order, reflecting the atomic activities’similarity, is automatically computed, (iii) the temporal dy-namics of elementary
Parameterized Modeling and Recognition of Activities
- Computer Vision and Image Understanding
, 1999
"... this paper we consider a class of human activities--atomic activities--which can be represented as a set of measurements over a finite temporal window (e.g., the motion of human body parts during a walking cycle) and which has a relatively small space of variations in performance. A new approach for ..."

Human Activity Analysis: A Review
- TO APPEAR. ACM COMPUTING SURVEYS.
"... Human activity recognition is an important area of computer vision research. Its applications include surveillance systems, patient monitoring systems, and a variety of systems that involve interactions between persons and electronic devices such as human-computer interfaces. Most of these applicati ..."

of these applications require an automated recognition of high-level activities, composed of multiple simple (or atomic) actions of persons. This paper provides a detailed overview of various state-of-the-art research papers on human activity recognition. We discuss both the methodologies developed for simple human
Machine recognition of human activities: A survey
, 2008
"... The past decade has witnessed a rapid proliferation of video cameras in all walks of life and has resulted in a tremendous explosion of video content. Several applications such as content-based video annotation and retrieval, highlight extraction and video summarization require recognition of the a ..."

The analysis of human activities in videos is an area with increasingly important consequences from security and surveillance to entertainment and personal archiving. Several challenges at various levels of processing—robustness against errors in low-level processing, view
Unsupervised Activity Perception in Crowded and Complicated Scenes Using Hierarchical Bayesian Models
- SUBMISSION TO IEEE TRANS. ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 2007
"... We propose a novel unsupervised learning framework to model activities and interactions in crowded and complicated scenes. Under our framework hierarchical Bayesian models are used to connect three elements in visual surveillance: low-level visual features, simple “atomic ” activities, and interacti ..."

Quantum random walks - an introductory overview
- Contemporary Physics
, 2003
"... This article aims to provide an introductory survey on quantum random walks. Starting from a physical effect to illustrate the main ideas we will introduce quantum random walks, review some of their properties and outline their striking differences to classical walks. We will touch upon both physica ..."

In recent years interest in quantum information theory has been generated by the prospect of employing its laws to design devices of surprising power [1]. New ideas include quantum cryptography [2, 3] and quantum computation. In 1994 Shor [4
Randomized active atomicity violation detection in concurrent programs
