In the field of computer vision, a crucial task is the detection of motion (also called optical flow extraction). This operation allows analysis such as 3D reconstruction, feature tracking, time-to-collision and novelty detection among others. Most of the optical flow extraction techniques work within a finite range of speeds. Usually, the range of detection is extended towards higher speeds by...

Accurate and consistent skull stripping of serial brain MR images is of great importance in longitudinal studies that aim to detect subtle brain morphological changes. To avoid inconsistency and the potential bias introduced by independently performing skull-stripping for each time-point image, we propose an effective method that is capable of skull-stripping serial brain MR images simultaneous...

Complex implant rehabilitations can include procedures requiring multiple phases of treatment, commonly referred to as staged approaches. The reasons for staged approaches are varied but usually involve serial extraction of hopeless teeth. These treatment plans both enable the patient to avoid removable prostheses by keeping natural teeth during healing phases, and circumvent the immediate load...

Active contour is an effective technique for object boundary extraction in biomedical images such as blood vessel tracing or optic disc extraction in retinal images. The traditional serial realization of contour finding needs considerable processing time. This paper presents a parallel realization of the active contour model to speed up the contour convergence process. The initially drawn conto...

Abstract Low frequency alternating magnetic field is one of the important features for marine detection. In order to realize effective detection low-frequency signal in environment, a device based on unstable platform was designed low-power optical pump magnetometer and control processing circuit this paper. The can be stored. power spectrum analysis, line purification, extraction so processed ...

isolated impacted supernumerary teeth are quite rare, but they can be seen associated with several syndromes such as cleidocranial dysostosis or gardner's syndrome. this article aims to discuss a case of sequential formation of supernumerary teeth with no other associated disease or syndrome. a 17-year-old iranian male with 8 impacted supernumerary teeth was referred to the department of pediat...
