Introduction to Artificial Intelligence ( AI ) : 6 Introduction to Artificial Intelligence ( AI ) What is AI ?
AI is a branch of computer science concerned with mechanize the human intelligent behavior.
AI is built with:
Database system: to represent acknowledgment and data.
Algorithms: describe how to use data.
Programming Languages: to represent both data and algorithms.
Introduction to Artificial Intelligence ( AI ) : 7 Introduction to Artificial Intelligence ( AI ) Importance of AI:
AI is the field where human brain and machine talks together.
Understand human intelligence and it's complicated operations.
The ability of building computer models for any field in the life and specify relation between its elements.

Slide 10 : 10 Pattern Recognition
Pattern recognition system : 11 Pattern recognition system What is Pattern recognition system?
Pattern recognition is a branch of artificial intelligence that involves identifying input data with the goal of understanding that input.
What is different between (PR) and (IP)?
Pattern recognition system : 12 Pattern recognition system Pattern recognition Procedure:
The first step of the procedure extracts from the input data which characterize the objects.
Based on these features, the objects are identified and stored into classes.
Pattern Recognition Approach :
Template-Matching and correlation Method.
Statical Approach.
Syntactic and Structural Approach.
Neural Networks Approach.
Pattern recognition system : 13 Pattern recognition system Feature extraction approach:
Slide 14 : 14 Speech Recognition
Speech Recognition : 15 Speech Recognition What is speech recognition?
It means that computer can identify human speech.
When the system receive your speech, three step will be accomplished:
Pre-Processing.
Recognition.
Communication
Speech Recognition : 16 Speech Recognition Pre-Processing:
Speech will be converted into binary form (0,1)
Speech Recognition : 17 Speech Recognition voice recorded is continuous signal.
continuous signal is converted into discrete signal.
Speech Recognition : 18 Speech Recognition then the discrete signal converted into binary form operation called QUANTIZATION. Time
Speech Recognition : 19 Speech Recognition 2. Recognition:
Speech will be processed using recognition methods which are identification and verification.
How?
Speech Recognition : 20 Speech Recognition Identification:
Every voice template has distance measurement differs from one to another.
Identification use distance measurement to distinguish between different voice.
Identification result not absolutely right but is nearly closer.
Verification:
Examine the result of identification weather it match the voice exactly or not.
Speech Recognition : 21 Speech Recognition 3. Communication:
To assign the result in different hardware and software
applications.
Applications of speech recognition:
Security : to allow or prevent entrance through secured establishments.
Mobiles : to dial up numbers using voice service.
Medicine : to diagnosis some illnesses.
Control : to control electrical devices with human speech.
Slide 22 : 22 Image Processing
Image Processing : 23 Image Processing What is image?
Image defined as a tow dimensional function F(x,y), where x, y are the coordinates of image.
What is image processing?
Techniques usually transform image into other image by improves or modifies the image quality (noise reduction, edge sharpening/detection).
Image Processing : 24 Image Processing Computer vision (CV): create a description of the imaged scene (Analysis of image).
Computer Graphics (CG): generates images from geometric primitives (described) such as lines, circles, and free-form surface (Synthesis of image).
Image Processing : 25 Image Processing What is difference between IP, CG, & CV?
Image Processing : 26 Image Processing Application of IP:
Medical image processing
Enhancement of X-ray, computed Tomography (CT).
Factory automation
Quality control
Robotics
Military
Target Tracking
Security
Finger/hand print analysis
Eye retina comparison
Face recognition
Weather mapping
Video conferencing
Image Processing : 27 Image Processing Steps of Image Processing:
Optical image capture
Analog image signals
-Video camera, television ,…
Digital image Processing
-Computer processor
Slide 28 : 28 Image Processing
Image Processing : 29 Image Processing Summary
Conclusion : 30 Conclusion The concept of AI is explained.
How the pattern recognition system used to classify pattern.
We able to realize the steps of speech processing system.
The image processing technique are listed and the main concepts depends on this system became obvious.
