Introduction: Information about vegetation cover and their health has always been interesting to ecologists due to its importance in terms of habitat, energy production and other important characteristics of plants on the earth planet. Nowadays, developments in remote sensing technologies caused more remotely sensed data accessible to researchers. The combination of these data improves the obje...
فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...
Many researchers adopt Local Binary Pattern for pattern analysis. However, the long histogram created by Local Binary Pattern is not suitable for large-scale facial database. This paper presents a simple facial pattern descriptor for facial expression recognition. Local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...
حالات چهره یکی از قوی ترین، متداول ترین و سریع ترین روش های انتقال احساسات و عواطف و منظورهای انسان ها به یکدیگر می باشد. شناسایی حالات جهره توسط کامپیوتر از موضوعات جدیدی است که نظر محققین را در دهه اخیر به خود جلب نموده است. بدلیل رفتار متنوع انسان ها و ابعاد وسیع مربوط به حالات چهره در افراد مختلف، شناخت و بررسی این حالات در انسان بسیار پیچیده می باشد. لذا با وجود تحقیقات وسیعی که در زمینه ه...

Introduction: The purpose of this study is to compare the emotion recognition and mind reading in opium abusers and healthy individuals. Method: In this causative-comparative study, with a non probability sampling method, 30 opium abusers compared with 30 healthy individuals that were matched in sex and education. Neurocognitive tests of reading mind from eyes and emotion recognition from face ...
Since money exchange is important in our daily life, many types of equipments such as Vending Machines, Currency Sorters, Automatic Teller Machines (ATM) and Currency Recognition systems for blind people have been made. More advanced devices with more capabilities are being made each day. As a result, efficient, fast and reliable currency recognition methods are required. Most currency recognit...
Hidden Markov Model is a popular statisical method that is used in continious and discrete speech recognition. The probability density function of observation vectors in each state is estimated with discrete density or continious density modeling. The performance (in correct word recognition rate) of continious density is higher than discrete density HMM, but its computation complexity is very ...
To investigate the effects of different glossing conventions on vocabulary recognition and recall, 158 participants were given a pre-test to make sure that they did not have any prior knowledge of the target words. Reading passages with four different glossing conventions (interlinear, marginal, pre-text, and post-text) were given to eight groups. Four groups received interlingual glosses and f...
Abstract Text recognition has been one of the growing research topics in recent years. Many of these researches have focused on recognition of letters and sub-words as a basis for identifying larger text structures such as words, phrases and sentences. This thesis presents a new method in which the recognized sub-words are combined in order to provide meaningful words and sentences in Farsi tex...
