Research ArticleOpen accessIn the abstractEDGE PRESERVED IMAGE COMPRESSION USING EXTENDED SHEARLET TRANSFORMS. Thayammal, D. SelvathiThe motivation of the proposed compression method is to reduce the bit rate for image transmission or memory requirement for image storage while maintaining image quality. The edges are one of the prominent features in an image and they are essential for maintaining image quality. JPEG compression standards like JPEG98 and JPEG2000 produce visual artifacts in reconstructed image at low … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,041 accessesView PDF Cite

Research ArticleOpen accessIn the abstractACCURATE AND FAST PUPIL LOCALIZATION USING CONTRAST STRETCHING, SEED FILLING AND CIRCULAR GEOMETRICAL CONSTRAINTSIman A. Saad, Loay E. George, Ahmad A. TayyarIris segmentation is the most contested issue in the iris recognition system, since noise and poor image quality can significantly affect accuracy of iris localization stage. Therefore, very careful attention has to be paid for the segmentation process if only an accurate result is expected. This study presents a new method for precise pupil detection capable of handling the unconstrained … …Journal of Computer Science, Vol. 10, Issue 2 · 16 Nov 2013 · 7,240 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Evaluation of the Epidural Dexmedetomidine, Ketamine or Fentanyl in Combination with Bupivacaine in DogsEman M. Nour, Mahmoud Mahmoud Othman, Gamal I.A. Karrouf, Adel E.I. ZaghloulCastration is one of the most common procedure. It is a potential source of mild to moderate pain which is enough to induce inflammatory process, necessitate the incorporation of analgesics. This study was designed to evaluate the effect of epidural bupivacaine alone or in association with fentanyl, ketamine or dexmedetomidine on analgesia for the first 24 h post surgical castration. … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 8 Nov 2013 · 7,188 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEdge Sensing Demosaicing Using Adaptive Weighted InterpolationDev R. Newlin, Elwin Chandra MonieDemosaicing is a process of obtaining a full color image by interpolating the missing colors of an image captured from a digital still and video cameras that use a single-sensor array. The edges are not handled properly in the existing demosaicking methods. This study provides an effective demosaicing algorithm applying an adaptive weighted-edge interpolation to handle green pixels. Due to … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 29 Apr 2013 · 6,960 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEfficient Pre-processing of USF and MIAS Mammogram ImagesAyman A. AbuBaker, R. S. Qahwaji, Musbah J. Aqel et al.High quality mammogram images are high resolution and large size images. Processing these images require high computational capabilities. The transmission of these images over the net is sometimes critical especially if the diagnosis of remote radiologists is required. In this paper, a pre-processing technique for reducing the size and enhancing the quality of USF and MIAS mammogram images is introduced. … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,167 accessesView PDF Cite
