Handwriting Recognition generally uses a dictionary : in the case of large vocabularies, our system helps checking the existence of the words provided by the recognizer, or when there is a model to go through per word, it will reduce the number of models to go through. In the case of smaller vocabularies it can be used as a recognizer. From the signal provided by a digitizing tablet we build a ...

We investigate a silhouette puzzle that is recently developed based on the golden ratio. Traditional silhouette puzzles are based on a simple tile. For example, the tangram is based on isosceles right triangles; that is, each of seven pieces is formed by gluing some identical isosceles right triangles. Using the property, we can analyze it by hand, that is, without computer. On the other hand, ...

Both three-dimensional (3D) and four-dimensional (4D) ultrasound have improved our knowledge regarding the develop ment of the embryo and fetus and of a great number of fetal anomalies. The great achievement in the field of 3D/4D ultrasound is HDlive technology. This technology is a novel ultrasound technique that improves the 3D/4D images. Furthermore, recent advanced 3D technology has produce...

This paper develops a biometric gait recognition system based on 3D video acquired by a Time-of-Flight (ToF) sensor providing depth and intensity frames. A first step of the proposed gait analysis is the automatic extraction of the silhouette of the person via segmentation. The segmentation of the silhouette is performed on the depth frame which provide information which describes the distance ...

In this paper we present a new approach to high quality 3D object reconstruction. Starting from a calibrated sequence of color images, the algorithm is able to reconstruct both the 3D geometry and the texture. The core of the method is based on a deformable model, which defines the framework where texture and silhouette information can be fused. This is achieved by defining two external forces ...
