In this paper an equalization technique for colour images is introduced. The method is based on n th root and n th power equalization approach but with optimization of the mean of the image in different colour channels such as RGB and HSI. The performance of the proposed method has been measured by the means of peak signal to noise ratio. The proposed algorithm has been compared with convention...
[1] We have completed the first global spatial deconvolution analysis of planetary gamma-ray data for lunar Th abundances as measured by the Lunar Prospector Gamma-ray Spectrometer. We tested two different spatial deconvolution techniques – Jansson’s method and the Pixon method – and determined that the Pixon method provides superior performance. The final deconvolved map results in a spatial r...
Th e acute toxicities of cadmium chloride (CdCl2.H2O), arsenic trioxide (AS2O3), and their mixtures to Daphnia magna were investigated by employing the statistical method of aquatic toxicity. Th e data obtained were statistically evaluated with probit analysis method (SPSS 17.0). Th e 24 h LC50 of Cd and As to Daphnia magna was estimated to be 44 μg L−1 for Cd, and 509 μg L−1 for As, respective...
در این مطالعه سعی شد که یکی از کانسرهای دهان که به نظر می رسد از کانسرهای شایع دهان در استان باشد، بررسی گردد. در نتیجه برای نیل به این هدف به آرشیو دو بخش پاتولوژی بیمارستان خاتم الانبیا و دانشکده دندانپزشکی زاهدان مراجعه و بیوپسی های ارسالی در 5 سال اخیر مورد کنکاش قرار گرفتند.
