Study Notes
Course Details
- The course is Digital Image Processing, taken in the first semester of the 2022-2023 academic year at Mansoura University.
- The course is taught by Dr. Nehal Sakr.
- The course meeting time is Thursday, 12:30 to 2 pm.
- The course uses MATLAB for practical implementations.
- The course is graded on participation (5%), project (5%), practical exam (10%), oral exam (10%), midterm (10%), and final exam (60%).
Course Objectives
- The goal of the course is to become familiar with digital image fundamentals.
- The course aims to expose students to simple image enhancement techniques in both the spatial and frequency domains.
- The course will teach students about degradation functions and restoration techniques.
- The course will cover image segmentation and representation techniques.
- The course aims to introduce students to image compression and recognition methods.
Signals and Images
- A signal is a mathematical function that conveys information.
- Signals can be one-dimensional, two-dimensional, or higher dimensional.
- A one-dimensional signal is a signal that is measured over time, such as a voice signal.
- A two-dimensional signal is a signal that is measured over some other physical quantity, such as a digital image.
- An image can be defined as a two-dimensional function f(x, y) where x and y are spatial coordinates.
- The amplitude of f at any coordinate (x, y) is called the intensity or gray level of the image at that point.
- A digital image is an image where x, y, and intensity values are all finite, discrete quantities.
Fields Related to Digital Image
- Computer graphics focuses on the synthetic creation of images.
- Image processing involves enhancing or manipulating images, often resulting in a new image.
- Video processing is similar to image processing but involves processing multiple images or frames.
- Computer vision analyzes and understands image content.
- Pattern recognition automates the detection of patterns and regularities in data.
Digital Image Processing
- Digital image processing refers to the processing of digital images using a computer to either:
- Improve pictorial information for human interpretation.
- Render the image more suitable for autonomous machine perception.
- Digital image processing can be broken into low-, mid-, and high-level processes.
- Low-level processes involve inputting an image and outputting an image, such as noise removal or sharpening.
- Mid-level processes involve inputting an image and outputting attributes, such as object recognition or segmentation.
- High-level processes involve inputting attributes and outputting understanding, such as scene understanding and autonomous navigation.
- This course will focus on low- and mid-level processes.
