The 2-D Convolution is an algorithm widely used in image and video processing. Although its computation is simple, its implementation requires a high computational power and an intensive use of memory. Field Programmable Gate Arrays (FPGA) architectures were proposed to accelerate calculations of 2-D Convolution and the use of buffers implemented on FPGAs(More)
Sign languages are visual-gestural languages used by deaf people to communicate with others. As with spoken languages, Sign languages vary among countries and have their own vocabulary and grammar. Since they suffer of an extreme variability within the same country as they don't have a standard lexicon. This paper describes a LIS Sign Bank, a large scale(More)
Humane care—which is an important design paradigm relevant for pervasive healthcare—means designing systems with care, keeping in mind both users and other stakeholders. Understanding human values is a key factor in creating any successful healthcare application and is essential to avoid dehumanizing and stigmatizing users. By considering(More)
This paper presents the ATLAS Editor for Assisted Translation (ALEAT), a novel tool for the Computer Assisted Translation (CAT) from Italian written language to Italian Sign Language (LIS) of Deaf People. The tool is a web application that has been developed within the ATLAS project, that targets the automatic translation from Italian written language to(More)
The Lack of written representation for Italian Sign Language (LIS) makes it difficult to do perform tasks like looking up a new word in a dictionary. Most of the paper dictionaries show LIS signs in drawings or pictures. It’s not a simple proposition to understand the meaning of sign from paper dictionaries unless one already knows the meanings. This paper(More)
In this paper, we present an experimental system that supports the translation from Italian to Italian Sign Language (ISL) of the deaf and its visualization through a virtual character. Our objective is to develop a complete platform useful for any application and reusable on several platforms including Web, Digital Television and offline text translation.(More)
