An image-based approach provides an eficient way for visual speech synthesis. In an image-based visual speech synthesis system, a few lip images, namely visemes, are used for generating an arbitrary new sentence. Many approaches select visemes manually. In this papel; we propose a method for a system to automatically select visemes by minimizing the synthesis error The feasibility of the propos...

E ective Human-to-Human communication involves both auditory and visual modalities, providing robustness and naturalness in realistic communication situations. Recent e orts at our lab are aimed at providing such multimodal capabilities for humanmachine communication. Most of the visual modalities require a stable image of a speaker's face. In this paper we propose a connectionist face tracker ...

Recently, several medical devices that use wireless communication are under development. In this paper, the small size frequency shift keying (FSK) transmitter and a monofilar antenna for the capsule endoscope, enabling the medical device to transmit VGA-size images of the intestine. To verify the functionality of the proposed wireless communication system, computer simulations and animal exper...

We present a design of a vision sensor device, implemented in a three-dimensional (3D) silicon on insulator (SOI) 150nm CMOS technology. The proof-of-concept device contains an image sensor array on one layer, and a pitchmatched array of 32x32 pixel-parallel processors, distributed over two further layers. The processor array uses mixed-mode processing elements and operates in SIMD (Single Inst...

This paper presents the design and performance evaluation of communication and video system for a multi-legged subsea robot which can work in shallow and strong tidal current and high turbidity environment by crawling sea floor. The design keys are hierarchical network structure based on Gigabit Ethernet and full digital video transmission. Especially, the digital video transmission can minimiz...

This paper presents a method of image processing used in a mono-vision system in order to study semiotic gestures. We present a robust method to track the hands and face of a person performing gestural communication and the Signs’ language communication. A model of skin is used to compute the observation density as a skin colour distribution in the image. Three particle filter trackers are impl...

Present stage Telepathology started in Europe in the 1980s. It was implemented in closed communication systems and focussed on frozen section service [1,2]. Open systems embedded in open source software replaced the early communication about 10 years ago. They became to age, and nearly all of them closed [3]. A new era started with the medical electronic communication expert system (MECES, http...

Noise estimation in digital images plays an important role in various kinds of applications such as medical imaging, video processing and communication systems. Noise density estimation from an image can help to analyze the channel properties of a communication system. Some authors have been described with a few algorithms to estimate noise present in the images in the spatial and frequency dom...

We demonstrate the prototype of an image understanding based system [2] to support decision making in clinical pathology. The system employs all four major low level vision queues (shape, texture, color, metric measures) in content-based retrieval of visual information. The reliability of the central module of the system, the fast color segmenter, makes possible on-line analysis of the query im...
