Atherosclerosis is a cardiovascular disease very widespread into population. It is characterized by a thickening of the arterial walls, which affects blood flow. The intima-media thickness (IMT) has emerged as a reliable early indicator of this pathology. Nowadays, the IMT is still measured by the physician using images acquired with a B-scan ultrasound.(More)
Artificial muscles are formed by attaching a conducting poly-meric film to a non-conducting one. Applying an electrical current on the muscle. a macroscopic bending movement appears on it. Study of curvature variations and related parameters , such as speed of motion or energy of curvature, is necessary for improving the efficiency of these devices. In a(More)
In this paper, an implementation of the Region Competition algorithm for segmenting stereoscopic video sequences is shown. This algorithm is an essential task in the method in order to obtain a 3D characterization of artificial muscles. Image sequences are acquired by a two-cam computer vision system. Optimal and efficient segmentation of these images is(More)
