Analyzing human shape variability is important for human system engineering and for animation applications where synthesizing realistic virtual humans is needed to re-create social human activities in historical and cultural context. In this paper, we present a new method for extracting main modes of variations of the human shape from a 3-D anthropometric(More)
Food quality depends mostly upon external appearance and in particular upon color. The purpose of this paper is to show a non destructive method for fresh cranberries color evaluation. A fresh cranberry color scale is built-up by machine vision system. Each cranberries batch to be evaluated is first photographed. The color which appears at the surface of(More)
The use of a laser range sensor in the 3D digitalization process allows significant improvement in acquisition speed and in 3D measurement point density. However, if we want to use these 3D data in applications that require data with a high degree of accuracy like inspection tasks, it is mandatory that the 3D points be acquired under the best conditions of(More)

In this paper we present a novel combination of object features to both match buildings from pre-disaster images to shapes in a post-disaster image and assess damage on those buildings. These features include scale profile ratios extracted from a tree of shapes representation of the original image as well as texture features. A supervised classifier is used(More)
The use of laser range sensor allows very significant improvement in acquisition speed but does not equal the accuracy obtained with a coordinate measuring machine. In order to obtain a quality control close to that obtained in metrology, we suggest to improve the accuracy of the depth measurements by positioning the sensor’s head according to a strategy(More)
Characterizing the variations of the human body shape is fundamentally important in many applications ranging from animation to product design. 3D scanning technology makes it possible to digitize the complete surfaces of a large number of human bodies, providing much richer information about the body shape than traditional anthropometric measurements.
