Purpose of class
To learn various basic algorithms for image processing, including convolution filtering, Fourier transform, affine transform, deconvolution. To improving programing skills through python programing exercises for image processing.
Course description
Image processing is indispensable for various fields, including industry, natural science, and entertainment. This class, Digital Media Processing, introduces basic image-processing techniques such as digital image acquisition, filtering, and geometric transform. For most of algorithms presented in class, interactive demonstrations with source codes (python) will be provided to support your deep comprehension.
Goals and objectives
  1. Introduction to digital image processing - Goal is that students understand various techniques of image acquisition and can explain them.
  2. Image filtering - Goal is that students understand basic filtering techniques, such as tone curve, linear and non-linear filters and can explain them.
  3. Geometric transformation – Goal is that students understand affine transform and interpolation and can explain them.
  4. Image compression – Goal is that students understand and explain basic information theory and image compression algorithms.
  5. Programing assignments - Goal is that students write programs of various basic image processing algorithms in python.

Evaluation method and criteria
By mini exams (20%), exam (40) and assignments (40%).
-- The mini exam and exam will contain basic questions (30~40%), developmental questions (20~30%), and calculation (30~40%) with respect to image processing.
-- Programming assignments contain basic assignments (60%) and developmental assignments (40%) with respect to image processing and image recognition.

If solving all basic questions and programming assignments, it will be evaluated as 60%.
