Image 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 کاملOn the Optimal Choice of Quality Metric in Image Compression
There exist many di erent lossy compression meth ods and most of these methods have several tunable parameters In di erent situations di erent methods lead to di erent quality reconstruction so it is impor tant to select in each situation the best compression method A natural idea is to select the compression method for which the average value of some metric d I e I is the smallest possible The...

متن کاملDigital Image Compression
When several gray midtones are present, like a black and white photo, two values are no longer sufficient to encode all the possible gray intensities, and to each pixel must be associated a numerical value, proportional to the brightness of that point. Typical choices for these values fall in the ranges 0 31 or 0 255 (requiring respectively 4 and 8 bits for each pixel). This second kind of imag...
متن کاملJPEG Compression Metric as a Quality-Aware Image Transcoding
Transcoding is becoming a preferred technique to tailor multimedia objects for delivery across variable network bandwidth and for storage and display on the destination device. This paper presents techniques to quantify the quality-versus-size tradeoff characteristics for transcoding JPEG images. We analyze the characteristics of images available in typical Web sites and explore how we can perf...
