    A Novel Blending Method for Automatic Seamless Image Mosaicing
    (Proc. of the Intl. Conf. on Advances In Computer and Electronics Technology- ACET 2014, 2014) Varol, Ahmet Hamdi
    An image mosaic is a panoramic image generated by assembling sequential images belong to the same scene . This method is mainly used in mapping applications, the evaluation of the images acquired from unmanned aerial vehicles, and various computer vision applications. In this study, we proposed a novel blending method for automatic seamless image mosaicing from ground level photos taken by an digital camera. For the correction of consistent seams occurred during the mosaicing, we measured the color differences around the overlapping regions. For this purpose, first, we determined the intensity values of image pixels inside and outside the overlapping region boundary within a 1 pixel wide zone. Secondly, the intensity values were averaged and finally, the average values of color differences were applied to overlapping regions. Besides, a motion blur filter was performed for the same boundary regions in order to reduce the seams. In order to test the accuracy, a subjective evaluation metric was used. According to the results obtained, the seamless image mosaics were generated with a subjective accuracy of 74%. Our results indicate that the seams can be substantially reduced or completely eliminated, and the illumination differences are minimized.

    Is sepsis still a problem in burns?
    (ANNALS OF MBC. 1, 3, 35-36, 1990) Haberal, Mehmet;Bayraktar, U;Oner, Z;Bilgin, N;Ozturk, S
    From Ist January 1988 to 31st December 1988, 61 patients were admitted to our Bums Centre. The overall mortality was 19.67% 12 patients died and 49 patients were discharged. 8 (13.11%) adult patients died due to sepsis; in 7 of them, the bum cause was flame and in one electricity. 4 children died due to sepsis (bum cause hot liquid). Pseudomonas grew in 10 patients (83.33%), 7 adults and 3 children, and mixed bacteria in 2 patients (16.67%): in one adult (Pseudomonas, E. coli and Staph. coag+) and in one child (Pseudomonas, Proteus and Enterobacter).In this study, the great majority of evidence gathered by us revealed that sepsis is still an important problem among the patients who have presented at our Burns Centre.
