BACKGROUND Self-medication, often without adult guidance, has been reported to be a common practice during adolescence. Similar to other preventable health-risk behaviors initiated in early adolescence, it has become a cause for concern universally. OBJECTIVE This study examines the prevalence of self-medication with both prescribed and non-prescribed(More)
This paper presents an automatic vision based system for qual ity control of yarn ends ready for spl icing, which is aimed to establ ish a standard qual ity measure and l ower manufacturing cost. New approach for defect detection and cl assification is presented. I n this approach, features describing the shape and surface defects are ex tracted and defects(More)
Harvesting energy from environmental sources has been of particular interest during these last few years especially from the electromagnetic waves. It has been recently reported that radio frequency rectennas (receiving antenna+ rectifying circuit), enable to collect microwave radiations and convert it to DC power [1-4]. The 60-GHz band is one potential(More)
A major problem in noisy image processing is the segmentation of its components. Many computer vision tasks analyze regions after segmenting a given image, then minimize the segmentation error to build a good automatic inspection system. In this paper, we propose a novel segmentation scheme for noisy images which consists of a new denoising method and a(More)
This paper presents an automatic vision-based system for unsupervised detection and classification of spliced yarn joints. In the splice detection process, a competitive learning method based on an LBG algorithm is used. In the splice classification process, a dynamic time warping (DTW) algorithm is used to classify the extracted splice joint into one of(More)
