A Variational Model for Infinite Perimeter Segmentations Based on Lipschitz Level Set Functions: Denoising while Keeping Finely Oscillatory Boundaries
We propose a new model for segmenting piecewise constant images with irregular object boundaries: a variant of the Chan-Vese model [10], where the length penalization of the boundaries is replaced by the area of their neighborhood of thickness ε. Our aim is to keep fine details and irregularities of the boundaries while denoising additive Gaussian noise. For the numerical computation we revisit...
متن کاملReconfigurable Wavelet Thresholding for Image Denoising while Keeping Edge Detection
This paper proposes an reconfigurable adaptive threshold estimation method for image denoising in the wavelet domain based on the generalized Guassian distribution (GGD) modeling of sub-band coefficients. The proposed method called RegularShrink is computationally more efficient and adaptive because the parameters required for estimating the threshold depend on sub-band data Edge information is...
متن کاملTwo-Level Convex Relaxed Variational Model for Multiplicative Denoising
The fully developed speckle (multiplicative noise) naturally appears in coherent imaging systems, such as synthetic aperture radar. Since the speckle is multiplicative, it is difficult to interpret observed data. Total variation (TV) based variational models have recently been used in the removal of the speckle because of the strong edge preserving property of TV and reasonable computational co...

هدف پژوهش حاضر ارائه ی الگویی بر اساس کنش گفتار و کارکرد زبان برای تدوین مطالب درس "بررسی آثار ترجمه شده ی اسلامی" می باشد. در الگوی جدید، جهت تدوین مطالب بهتر و جذاب تر، بر خلاف کتاب-های موجود، از مدل های سطوح گفتارِ آستین (1962)، گروه بندی عملکردهای گفتارِ سرل (1976) و کارکرد زبانیِ هالیدی (1978) بهره جسته شده است. برای این منظور، 57 آیه ی شریفه، به صورت تصادفی از بخش-های مختلف قرآن انتخاب گردید...
15 صفحه اولVariational Geometry with Algebraic Level Set Model
Variational Geometry technique, also known as Constraints Satisfaction Problem technique (CSP), is one of the core components in modern CAD systems. One of the known problems of the existing technique is its inability of solving topological changes. In this paper, we propose a new Varaitional Geometry technique with Algebraic Level Set (ALS) geometric model. Based on half-space model theory and...
