Recognition of License Plates
  • Objectives
  • Identification of car number plates in complex
    background.
  • 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 doesnt 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.

7
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.

8
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
  • 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.

10
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.

11
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.

12
Arabization Projects
  • Neural Network based Speech recognition.
  • The proposed project aims at investigating
    various structures for ANN/HMM models for phoneme
    recognition or next generation Arabic Speech
    recognition. Carnegie Mellon Sphinx-4 will be
    used as our testing platform.

19
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 use Constrained Least Squares, or Iterative
Least Squares, or Maximum Likelihood

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


23
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
25
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.

29
The Overall Trust Model

30
Utility of The Trust Model
  • Integrating trust into resource management
    systems (RMSs)
  • The idea is to make trust cognizant resource
    allocations
  • Integrating trust into computing utility
    environments
  • Introducing the notion of trusted regions

31
Friendly Active Network System
  • Objective To introduce active networks in
    different areas
  • Improper website blocking
  • Access controls
  • Congestion Control
  • Active Network system with capabilities to handle
    both capsule-based and out-of-band architecture
    based on applications.

32
Real-time and Simulation
  • Access control using expert system, artificial
    neural networks and parallel rules have been
    tested on both active and non-active platforms.
  • Real-time platform
  • Language used Java.
  • Clustering of PCs using PVM.
  • Heterogeneous platforms used.
  • Processing on the fly was tested by linking the C
    code of PVM to handle MATLAB applications.
  • A 16-node Active Network system with both ergodic
    and non-ergodic capabilities have been tested on
    NS Simulator.

33
Planned Future Work
  • In general, the access lists are fixed for a
    network and so its easy to parallelize them and
    then apply it using active networks approach.
  • Future work requires parallelize the rules
    on-the-fly and allocated job to the respective
    routers using active networks.
  • To induce routing decisions using active
    networks. One scenario is to make Link-state
    protocols stabilize faster.

41
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
