    • Plate extraction from poor images with low contrast, glare affected intensity profiles and motion blur.

    • Character Segmentation from plates at high tilt or image skew.

    • Recognition under a rule base pertinent to Saudi Arabian number plate licensing standards.

    • Establishment of a standard number plate database that doesn’t exist for Saudi Arabia (Arabic plates) at the moment.

    • Development of novel and promoted techniques in the domain of Image Processing, Computer Vision and Machine Learning.


Proposed and implemented approach l.jpg

Proposed and Implemented Approach

  • Approach

    • Mainly involves three phases: Extraction, Segmentation and Recognition

  • Achievements

    • Contrast Adjustment using Histogram Stretching

    • Local feature extraction based on prevalent image edge profiles and break lights.

    • Plate extraction using modified Fuzzy Vector/Euclidean edge detection based techniques.

    • Character segmentation using a bi-cluster Fuzzy C-means algorithms

    • Recognition of segmented character bitmaps using PCA.


Development possibilities with intel l.jpg

Development possibilities with Intel

  • A practical License Plate Recognition (LPR) System requires high quality Image Grabbing Devices for operations that are, otherwise, very time consuming under software simulators.

  • An LPR system in practice is a part of an Intelligent Transport System.

    • Supports numerous PC clusters for real-time data link.

    • Complex image processing tasks are performed in parallel using multiple computers.

  • A number of such operations that are built over hardware in real time systems are

    • Frame Averaging

    • Image Differencing

    • Color level conversions

    • Edge and Intensity Adjustment operations.

    • Segmentation and Labeling

  • Significant work has been done in the recognition of US, EU, Japanese, Korean and Chinese License plates. A practical License Plate Recognition (LPR) System is needed NOT just for the local need of the Kingdom but also at a global level which can include various other Arab countries in the neighbor.

  • The project will be useful for various applications and can be used to enforce speed limits on expressways/roads, monitor traffic flows at traffic signals, record parking statistics at lots, car theft monitoring, Border Crossing, etc.


Arabization projects l.jpg

Arabization Projects

  • Arabic Text-to-Speech (ATTS)

    Two types of speech units were used independently: The first consists of 375 diphones of Arabic sounds, and the other has 178 allophones which cover Arabic and English sounds. The project developed extensive Arabic linguistic tools including: Arabic pronunciation rules, and tables of irregularly pronounced Arabic words, and allophone/diphone selection rules. A parametric model was also built to synthesize the speech and to give the user control over the pitch rate, stress, and speech tempo.


Arabization projects9 l.jpg

Arabization Projects

  • Automatic Generation of the Arabic Diacritical Marks

    We formulated the problem of generating Arabic diacritized text from unvoweled text using Hidden Markov Models (HMM) approach. The word sequence of unvoweled Arabic text is considered an observation sequence from an HMM, where the hidden states are the possible diacritized expressions of the words. The optimal sequence of diacritized words (or states) are then obtained efficiently using a Viterbi like Algorithm. The first phase of this project has already achieved 94.5% letter accuracy.


Arabization projects10 l.jpg

Arabization Projects

  • Arabic Speech Recognition System

    • The project aims at building sufficient know how and a state-of-the-art research base for the development of the next-generation speech recognition techniques for the Arabic language.

    • This project uses Carnegie Mellon University Sphinx-II, Sphinx-III and Sphinx-IV ASR engines and tools as a base for building a state-of-the-art large-vocabulary speaker- independent continuous Arabic ASR systems.

    • The project involves building a large Arabic speech corpus, an Arabic phonetic dictionary, training Arabic triphone parametric models, and development of extensive tools for modeling Arabic natural language.

    • The project is executed jointly with the Center of Speech and Phonological Science at King Abdulaziz City of Science and Technology.

    • Target application: Automatic TV/Radio news transcription.

    Slide17 l.jpg

    Functional Networks Classifier Learning Algorithm

    We assume that the probability can be written as:

    where are unknown, but unrestricted functions to be learned from the data, and p(.) must satisfy the two probability conditions, and is unknowns. For example, p(.) can be a Probit or Sigmoidal or CDF or Mulinomial logistic functions.

    In functional networks, we learn functions (not parameters)

    by approximate them by linearly independent family:

    The parameters can be learned using optimization methods.

    The response is:

    We useConstrained Least Squares, or Iterative Least Squares, or Maximum Likelihood

    Develop fuzzy logic models to generate permeability traces in non cored wells l.jpg

    Develop Fuzzy Logic Models to Generate Permeability Traces in Non-Cored Wells

    • Carbonate rocks pose an extreme challenge for mapping rock properties, especially porosity and permeability, due to their variable and complex pore structure

    • Fuzzy Logic asserts that the reservoir consists of several litho-types, each having characteristic distributions for permeability and electrical log values. Fuzzy Logic attempts to uncover the relationship between these distributions.

    • Objective:Develop expertise in fuzzy logic permeability modeling that uses conventional open-hole logs


    Slide21 l.jpg

    The Fuzzy Mathematics of Litho-Facies Prediction

    The normal distribution is given by:

    (1)

    P(x) is the probability density that an observation x is measured in the data-set described by a mean m and standard deviation s.

    In statistics the area under the curve described by the normal distribution represents the probability of a variable x falling into a range, say between x1 and x2.

    The curve itself represents the relative probability of variable x occurring in the distribution. That is to say, the mean value is more likely to occur than values 1 or 2 standard deviations from it.

    This curve is used to estimate the relative probability or “fuzzy possibility” that a data value belongs to a particular data set. If a litho-facies type has a porosity distribution with a mean m and standard deviation s the fuzzy possibility that a well log porosity value x is measured in this litho-facies type can be estimated using Equation 1. The mean and standard deviation are simply derived from the calibrating or conditioning data set, usually core data.

    Permeability Prediction in the Ula Field


    Slide23 l.jpg

    Permeability Prediction From NMR Data

    • Permeability prediction by fuzzy logic allows better choice of perforating intervals and can be applied to model building to map permeability, although it is still reliant on a good core permeability database.

    • The RGPZ and GAFL models work exceptionally well as a permeability predictor on core and log data, performing better overall than the SDR and Coates models.

    Software Engineering research project

    • Project: Investigating Design Quality Characteristics for Refactoring and Refactoring To Patterns Using Software Metrics

    • Objective: to confirm or invalidate the claims that cost and time put into refactoring are worthwhile.

    • In this research we will investigate:

      • An approach to detect the need to refactor early in the software process.

      • Two refactoring approaches: refactoring to produce design patterns, and refactoring that produces code without design patterns.

    • Using software metrics, we will quantitatively investigate whether those approaches really improve software quality or not
