An Effective 3D Ear Acquisition System
The human ear is a new feature in biometrics that has several merits over the more common face, fingerprint and iris biometrics. It can be easily captured from a distance without a fully cooperative subject. Also, the ear has a relatively stable structure that does not change much with the age and facial expressions. In this paper, we present a novel method of 3D ear acquisition system by using...
متن کاملCoarse to fine: toward an intelligent 3D acquisition system
The 3D acquisition-compression-processing chain is, most of the time, sequenced into independent stages. As resulting, a large amount of 3D points are acquired whatever the geometry of the object and the processing to be done in further steps. It appears, particularly in mechanical part 3D modeling and in CAD, that the acquisition of such an amount of data is not always mandatory. We propose a ...
متن کاملPortable cost-effective EEG data acquisition system.
Neuro-cognitive dysfunctions are common clinical abnormalities found in society. They require objective analysis by various instruments; an important technique involves monitoring electroencephalogram (EEG) signals. To date, EEG machines have been robust, costly and require patients to come to a hospital for test. Therefore, we have constructed a simple, cheap and portable EEG instrument for wi...
متن کاملA coarse to fine 3D acquisition system
The 3D chain (acquisition-processing-compression) is, most of the time, sequenced into several steps. Such approaches result into an one-dense acquisition of 3D points. In large scope of applications, the first processing step consists in simplifying the data. In this paper, we propose a coarse to fine acquisition system which permits to obtain simplified data directly from the acquisition. By ...
متن کاملA 3D acquisition and modelling system
This paper presents our implementation of an integrated 3D acquisition and modelling system. The proposed system consists of an acquisition module, a registration algorithm proposed by the last two authors and a reconstruction module. Techniques for addressing the implementation of the modules are first briefly followed by a more detailed discussion of the techniques implemented in the system i...
