TL;DR: A successful adaptation of the traditional strategy applied in the design of spoken language recognition systems to the new domain of full body gesture recognition, to allow users to control their environment is described.
Abstract: This paper describes a proposal for a full body gesture recognition system to be used in an intelligent space to allow users to control their environment. We describe a successful adaptation of the traditional strategy applied in the design of spoken language recognition systems, to the new domain of full body gesture recognition. The experimental evaluation has been done on a realistic task where different elements in the environment can be controlled by the users using gesture sequences. The evaluation results have been obtained applying a rigorous experimental procedure, evaluating different feature extraction strategies. The average recognition rates achieved are around 97 % for the gestural sentence level, and over 98 % at the gesture level, thus experimentally validating the proposal.

TL;DR: A novel model is presented for generating the facial sketch of pen-and-ink style and reproducing facial expressions in facial sketch animation, based on pseudo-muscle model, which is significative for multimedia application in low bandwidth communication environment.
Abstract: The ability to analyze a human’s facial expressions and reproduce them is important for fun communication. In this paper, a novel model is presented for generating the facial sketch of pen-and-ink style and reproducing facial expressions in facial sketch animation. Facial sketch rendering is implemented by combing the painting path and line template, in which personalized painting path ensures the generated facial sketch to fit the specific face, and line templates bring different styles to it. The animation of facial sketch, which is based on pseudo-muscle model, reproduces some specific expressions in 2D facial sketch. These works are significative for multimedia application in low bandwidth communication environment.

TL;DR: The experimental results show that this system can support the operator's fingers non-contact accurately to simulate actions of mouse clicks, synchronous positioning and trigger detection operations, etc.
Abstract: A non-contact human-computer interaction system based on gesture recognition is presented in this paper. It tracks and collects the operator's gestures image via two digital high-definition video cameras at a specific location, uses Image Recognition Algorithms to detect gestures change information, and thus controls mouse movements on the computer screen. The experimental results show that this system can support the operator's fingers non-contact accurately to simulate actions of mouse clicks, synchronous positioning and trigger detection operations, etc. This system can be widely used in large screen media show, intelligent scheduling monitoring, interactive teaching entertainment and other many human-computer interaction occasions.

TL;DR: SketchSeeker introduces a technique for indexing sketches in extremely compressed representations, which allows for fast, accurate retrieval augmented with a multilevel ranking subsystem and shows significant improvements in terms of storage requirements, speed, and accuracy.
Abstract: Searching is a necessary tool for managing and navigating the massive amounts of data available in today's information age. While new searching methods have become increasingly popular and reliable in recent years, such as image-based searching, these methods may be more limited than text-based means in that they do not allow generic user input. Sketch-based searching is a method that allows users to draw generic search queries and return similar drawn images, giving more user control over their search content. In this paper, we present SketchSeeker, a system for indexing and searching across a large number of sketches quickly based on their similarity. SketchSeeker introduces a technique for indexing sketches in extremely compressed representations, which allows for fast, accurate retrieval augmented with a multilevel ranking subsystem. SketchSeeker was tested on a large set of sketches against existing sketch similarity metrics, and it shows significant improvements in terms of storage requirements, speed, and accuracy.
