This paper presents an efficient human recognition system which makes use of vein patterns obtained from the back of the hand. It has used a new reflection-based image capturing environment to ensure high quality images through least effort and cost. The proposed recognition system automatically detects the region of interest (ROI) from the image and does the necessary preprocessing to extract ...

cryptosporidium is an important cause of illness in farm animals. the present study conducted in kerman, iran between 2003-2004 to elucidate the epidemiology of cryptosporidium infection in sheep and goats. fecal samples were collected fresh and transferred to the research lab. cryptosporidium oocysts were concentrated using formalin-ether sedimentation method followed by the modified ziehl-nee...

Zusammenfassung. Bei der Untersuchung von Röntgenbildern der Brust dienen Mikroverkalkungen als erste Hinweise auf einen Tumor. Durch die Unauffälligkeit dieser Merkmale werden 10-30% der Erkrankungen übersehen und daher die Heilungsaussichten drastisch verringert. Ein Zweitgutachter in Form eines Computers kann diese Rate verringern und den Radiologen auf Abweichungen aufmerksam machen. Ein Co...

Multiple frame prediction has proved successful in increasing the performance of motion compensated video coders. Region-of-interest (ROI) coding in conjunction with a dual frame predictor can lead to interesting design choices on how to allocate the available bitrate among the frame regions. In this work, we tackle the problem of applying ROI coding on aerial imagery and then on standard video...

In this paper, we present an image compression scheme based on the automatic segmentation of regions of interest (RoI) and a lossy wavelet compression algorithm adapted to this segmentation. Quasi-lossless compression is applied to the RoI while lossy compression is allowed outside the RoI, preserving at best the visual quality of the decoded image within a deened RoI. In fact, for diagnostic a...
