Course Description
Digital image processing is among the fastest growing computer technologies of the 1990s. With increasing computer power, it is now possible to do numerically many tasks that were previously done using analogue techniques. The objective of this course is to provide an introduction to the theory and applications of digital image processing. Topics will include fundamentals of image acquisition, image enhancement, transformations and filters, compression, segmentation and edge detection, and recognition.
Course Prerequisites
CS 202 and MATH 352. Good working knowledge of data structures such as linked lists, trees, and dynamically allocated structures is also required.If you do not meet the prerequisite requirements for this course, you should see me immediately !!

Software

Imgst ar (has been installed on the linux machines in /usr/local with appropriate executa bles in bin/, libraries in lib/ and include files in include/)
KHOROS (has been installed on ju niper in /staff2/bebis ; before you run KHOROS for the first time, run the command "kc onfigure" and answer the questions that the system will ask you; to run KHOROS, type "cantata" )
CVIPtools (has been installe d on juniper in /staff2/bebis ; to run it, enter "CVIPtools"; there is al so on-line help)
XIL (has been installed on juniper in /opt/SUNWsdk/xil; it is library of functions for development of visual applications)
