Enhancement Techniques for Panoramic Images
The aim of the presented work is to enhance the panoramic images (panoramas) that are generated from omnidirectional images (ODI). Blurring occurs in certain regions of these panoramas due to the high upsampling rate employed while converting from ODIs. The enhancement effects of standard interpolation methods are evaluated and several feature-based techniques are developed to solve the blurrin...
متن کاملImage quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...

متن کاملCochlear microphonic enhancement in two tone interactions.
Two tone interaction functions of the cochlear microphonic (CM) were obtained from pigmented guinea pigs. First (basal) cochlear turn recording locations show optimally enhanced levels of CM when the interfering tone (F2) was positioned about 4 kHz above probe tones (F1) of 12 kHz and 20 kHz. Maximum enhancement occurred for equal level tones. No enhancement was seen for a probe tone of 4 kHz. ...
