A face recognition algorithm based on local binary Haar feathers which represented as Kadane optimizing multi-threshold AdaBoost was proposed according to the problems of texture shape feature representation and classification algorithm accuracy in the process of facial classifying detection and recognition, First, improve the traditional expression by using image Local binary pattern of Haar f...
In this paper, we have proposed a Haar wavelet quasilinearization method to solve the well known Blasius equation. The method is based on the uniform Haar wavelet operational matrix defined over the interval [0, 1]. In this method, we have proposed the transformation for converting the problem on a fixed computational domain. The Blasius equation arises in the various boundary layer problems of...
Texture is the term used to characterize the surface of a given object or phenomenon and is an important feature used in image processing and pattern recognition. Our aim is to compare various Texture analyzing methods and compare the results based on time complexity and accuracy of classification. The project describes texture classification using Wavelet Transform and Co occurrence Matrix. Co...
تبدیل موجک یک روش مفید و جدید برای تحلیل سیگنالهاست. توابع موجک، ترکیبی از یک سری توابع اساسی هستند که قادر به تفکیک یک سیگنال در زمان و فرکانس میباشند. بنابراین، تبدیل های موجک قادرند بسیاری از جنبه های ناشناخته اطلاعات را که دیگر روش های تحلیل سیگنال (از جمله تبدیل فوریه) نمیتوانستند آشکار کنند، موجب تشخیص و آشکارسازی قرار دهند. در این مقاله به معرفی یک روش غیرمخرب، کارآمد و دقیق مبتنی بر ...
Recently it has been shown that in Image Processing, the usual sum and product of the reals are not the only operations that can be used. Several other operations provided by fuzzy logic perform well in this application. We continue this line of research and we propose the use of a pair consisting of a uninorm and an absorbing norm determined by a continuous, strictly increasing generator inste...
This informal set of notes contains some of the new results which will appear in the author’s 2013 dissertation. We show that every infinite product of locally compact non-compact groups decomposes into the disjoint union of a Haar null set and a meager set, which gives a partial positive answer to a question of Darji. We also show that the compact sets in each such product group are always Haa...
