Course Description

Course Description: This course covers the investigation, creation and manipulation of digital

images by computer. The course consists of theoretical material introducing the mathematics

of images and imaging. Topics include representation of two-dimensional data, time and

frequency domain representations, filtering and enhancement, the Fourier transform,

convolution, interpolation. The student will become familiar with Image Enhancement, Image

Restoration, Image Compression, Morphological Image Processing, Image Segmentation,

Representation and Description, and Object Recognition.

Course Objectives: The objective of this course is to make students able to:

Ø develop a theoretical foundation of Digital Image Processing concepts.

Ø provide mathematical foundations for digital manipulation of images; image

acquisition; preprocessing; segmentation; Fourier domain processing; and compression.

Ø gain experience and practical techniques to write programs for digital manipulation of

images; image acquisition; pre-processing; segmentation; Fourier domain processing;

and compression.
