EL5123 /BE6223 ---- Image Processing, Fall 2013
Course Description: This
course introduces basic concepts and techniques in digital image processing:
image acquisition and display using digital devices, properties of human visual
perception, sampling and quantization, sampling rate conversion, contrast
enhancement, two-dimensional Fourier transforms, linear and nonlinear filtering,
morphological operations, noise removal, image deblurring,
edge detection, image registration and geometric transformation, and multiresolution representation using wavelets, and image
compression (including the JPEG and JPEG2000 standard). Students will learn to
implement some image processing algorithms on computers using C-programming or
Prerequisites: EE 3054 (Signals,
Systems, and Transforms), Knowledge of basic matrix operations and probability;
basic programming skill; senior or graduate student status. This course can be
used to form a two-course sequence with EL6122 or EL5823.
