Face detection in image with complex background

This paper deals with an approach to detect face from image with complex background. That can be use in many areas (eg. security systems, biometrics, telecommunications, etc.).In the first part there is presented brief overview of common used method for face localization in image. On the basis of comparison of its properties there was developed appropriate combination of several methods with pa...

X-ray Image Detection by Electronic Methods.

In diagnostic radiology, the excellence of the conventional radiographic screen-film combination as a means of detecting and displaying the X-ray pattern (the radiation image) is qualified by its inability to show movement. The technique of fluoroscopy, in which the light image on the fluorescent screen is viewed by the dark-adapted but otherwise unaided eye, has long been employed in an attemp...

X-Ray Background Fluctuations

Minor Ha activity, consisting of small brightenings and small, surgelike spikes, was observed to take place above an active center at the solar limb in good time-association with small fluctuations in the soft X-ray background flux, suggesting that even small dynamical events seen optically are associated with coronal heating. The ratio of Ha flux to soft X-ray flux in some of the surges was ap...

fuzzy-based medical x-ray image classification

in this paper a novel fuzzy scheme for medical x-ray image classification is presented. in this method, any image is partitioned in to 25 overlapping subimages and then shape-texture features are extracted from shape and directional information extracted from any subimage. in the classification stage, we apply a fuzzy membership to any subimage with respect to euclidean distance between feature...
