        In this course you will first learn the fundamentals of processing gray scale images:
image files, contrasting, histogram equalization and dual histogram equalization,
linear and nonlinear transformations, sharpening, smoothing, blurring, edge detection,
and line drawings with line thinning. Also covered are image registration and fusion of multiple image frames.
Further topices include geometrical methods: zooming in and out, interpolation, rotation, affine
transformations, morphing, dilation and eroding, and segmentation.
Then come spectral analysis and frequency domain filtering.
The topics color, color models and color images are next, to be covered in depth.
File formats are to be discussed last.

        The tools used in this course are: Matlab, XView and LView Pro (mostly Matlab) and students will also write C/C++ programs for special algorithms.

The design of a project is to be done by each project group for the major effort of this course.

A formal report on the project, its purpose, design and results will be handed in by each project group. This report must be well written and demonstrate state-of-the-art image processing. It is a research project and report.

Instructions for Project Reports





























NOTICE: There is no way to embed the Word Perfect Math fonts in the PDF files (licensing doesn't permit it). Therefore I have printed out 2 copies of Units 5, 6, 7 (Unit 8 will not have Math. symbols) that students can check out for 1 hour each to photocopy the pages with symbols or write in the symbols. I'm sorry that we got caught in a non-standarization [the files do not convert properly to MS Word either].
