Determination of fractal dimensions from equivalent L systems

FONT DISCRIMINATIO USING FRACTAL DIMENSIONS

One of the related problems of OCR systems is discrimination of fonts in machine printed document images. This task improves performance of general OCR systems. Proposed methods in this paper are based on various fractal dimensions for font discrimination. First, some predefined fractal dimensions were combined with directional methods to enhance font differentiation. Then, a novel fractal dime...

Evaluation of fractal dimensions for analysis of aggregate stability

ارزیابی کارایی مدل‌های فرکتا‌لی در توزیع اندازه ذرات رسوب (مطالعه موردی: فولاد محلهِ سمنان)

The objective of current study was to invstigate the accuracy of Tyler and Wheatcraft, Bird et al. and Kravchenko and Zhang fractal models in describing particle size distribution (PSD) of sediment in 14 successive check dams for two depths of 0-15 and 15-30 cm. Sediment PSD were determined in 28 samples using hydrometer method . The referred fractal models were fitted on sediments PSD data. Re...

Pedotransfer functions for estimating soil moisture content using fractal parameters in Ardabil province

Extended abstract 1- Introduction Soil moisture curve is an important characteristic of soil and its measurement is necessary for determining soil available water content for plant, evapotranspiration and irrigation planning. Direct measurements of soil moisture coefficients are time-consuming and costly. But it is possible to estimate these characteristics from readily available soil propert...

On The Behavior of Malaysian Equities: Fractal Analysis Approach

Fractal analyzing of continuous processes have recently emerged in literatures in various domains. Existence of long memory in many processes including financial time series have been evidenced via different methodologies in many literatures in past decade, which has inspired many recent literatures on quantifying the fractional Brownian motion (fBm) characteristics of financial time series. Th...
