Duality of log-polar image representations in the space and spatial-frequency domains
In this paper, we study the result of applying a lowpass variant filtering using scaling-rotating kernels to both the spatial and spatial-frequency representations of a two-dimensional (2-D) signal (image). It is shown that if we apply this transformation to a Fourier pair, the two resulting signals can also form a Fourier pair when the filters used in each domain maintain a dual relationship. ...
متن کاملStudy on Image Color Stealing in Log-Polar Space
This paper proposes a cluster-to-cluster image color transform algorithm. Suntory Flowers announced the development of world's first blue rose “APPLAUSE”. Since roses lack the blue pigment, it was long believed to be impossible. The key to success lies in the introduction of blue gene from pansy into rose. In the previous paper, PCA matching model was successfully applied to a seasonal color ch...

مطالعه حاضر با هدف بررسی وجود رابطه ی ممکن میان هوشهای زبانی و منطقی زبان آموزان انگلیسی و تعداد و انواع مغلطه های زبانی و شواهد در متنهای استدلالی آنان انجام پذیرفته است.بدین منظور، 70 زبان آموز با سطح زبانی متوسط به بالا از دو موسسه زبان انگلیسی در ایران انتخاب شده و پرسشنامه های مزبوطه را تکمیل نموده و متنی استدلالی نوشتند. متون نوشته شده مورد بررسی قرار گرفته و نمرات پرسشنامه ها محاسبه شده ...
15 صفحه اولCombinational image watermarking in the spatial and frequency domains
In order to provide more watermarks and to minimize the distortion of the watermarked image, a novel technique using the combinational spatial and frequency domains is presented in this paper. The splitting of the watermark image into two parts, respectively, for spatial and frequency insertion relies on the user’s preference and data importance. Experimental results provide the comparisons whe...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
