A Comparison of Whitespace Normalization Methods in a Text Art Extraction Method with Run Length Encoding
Text based pictures called text art or ASCII art can be noise in text processing and display of text, though they enrich expression in Web pages, email text and so on. With text art extraction methods, which detect text art areas in a given text data, we can ignore text arts in a given text data or replace them with other strings. We proposed a text art extraction method with Run Length Encodin...

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
Run-length Encoding for Volumetric Texture
With the dramatic increase of 3D imaging techniques, there is a great demand for new approaches in texture analysis of volumetric data. In this paper, we present a new approach for volumetric texture analysis using a runlength encoding matrix and its texture descriptors. We experiment with our approach on the volumetric data generated from two normal Computed Tomography (CT) studies of the ches...
متن کاملA New Optimization Model for Designing Acceptance Sampling Plan Based on Run Length of Conforming Items
The purpose of this article is to present an optimization model for designing an acceptance sampling plan based on cumulative sum of run length of conforming items. The objective is to minimize the total loss including both the producer and consumer losses. The concept of minimum angle method is applied to consider producer and consumer risks in the optimization model. Also the average number o...
متن کاملAsymptotic Analysis of Run-Length Encoding
Gallager and Van Voorhis have found optimal prefix-free codes κ(K) for a random variable K that is geometrically distributed: Pr[K = k] = p(1 − p) for k ≥ 0. We determine the asymptotic behavior of the expected length Ex[#κ(K)] of these codes as p → 0: Ex[#κ(K)] = log2 1 p + log2 log 2 + 2 + f ( log2 1 p + log2 log 2 )
