among investments in different sections of economy, investment in agriculture is great importance. in addition to increasing production and job opportunities in agriculture, investment in this section will help to increase these in other sections as well, due to back and front relations with other economic activities. due to the fact that investment does not yield rapidly, and it takes some tim...

This paper develops an entire communication support system for speech handicaps using lip reading. Our system is a high level system and consists of a face detector using Viola-jones method, lip detector based on active appearance model, utterance section detector, determined phrase recognizer using DP matching, camera controller, and message output. We implemented our system in the commercial ...

In this paper we analyzed the problem of investigating locally the scalar curvature of the two dimensional kinematic surfaces foliated by the homothetic motion of an eight curve in LorentzMinkowski 5-space . We express the scalar curvature of the corresponding two dimensional kinematic surfaces as the quotient of hyperbolic functions { }. From that point, we derive the necessary and sufficient ...

The Active Appearance Model (AAM) algorithm is a powerful tool for modeling images of deformable objects. AAM combines a subspace-based deformable model of an object’s appearance with a fast and robust method of fitting this model to a previously unseen image. The speed of this algorithm comes from the assumption that the gradient matrix is fixed around the optimal coefficients for all images. ...

Which neighborhoods experience physical improvements? In this paper, we introduce a computer vision method to measure changes in the physical appearances of neighborhoods from time-series street-level imagery. We connect changes in the physical appearance of five US cities with economic and demographic data and find three factors that predict neighborhood improvement. First, neighborhoods that ...

Kurzfassung. In diesem Beitrag werden Active Appearance Models (AAMs) zur Segmentierung der äußeren Kontur von Aortenaneurysmen eingesetzt. Diese Aufgabe ist wegen des geringen Kontrastes zum umliegenden Gewebe und des Aufbaus der teils thrombotisierten oder kalzifizierten Gefäßwände im Bereich eines Aneurysmas so komplex, dass sie aufgrund der Vielgestalt der Kontur in CT-Angiographie-Bildern ...

Perception of one's body is related not only to the physical appearance of the body, but also to the neural representation of the body. The brain contains many body maps that systematically differ between right- and left-handed people. In general, the cortical representations of the right arm and right hand tend to be of greater area in the left hemisphere than in the right hemisphere for right...

Four studies examined whether Israeli 5-year-olds (N = 88) and adults (N = 48) drew inferences about psychological properties based on a character's social category, personality trait, or physical appearance trait. Study 1 revealed that while children drew inferences mostly by social category, adults did it by personality trait. Study 2 showed that the children's pattern was not due to how the ...

Active Appearance Models (AAMs) are able to align efficiently known faces under duress, when face pose and illumination are controlled. We propose Adapted Active Appearance Models to align unknown faces in unknown poses and illuminations. Our proposal is based on the one hand on a specific transformation of the active model texture in an oriented map, which changes the AAM normalization process...
