This course provides you to learn about digital image processing technology which is one of the primary media technology for ICT. You will learn on basic method, theory and element technology for handling images with computer. Moreover, you will deepen your understanding of the general principles of the This course provides you to learning about digital image processing technology which is one of the primary media technology for ICT. You will learn on basic method, theory and element technology for handling images with computer. Moreover, you will deepen your understanding of the general principles of the image processing, by actually applying some image processing algorithms to an image to compare and confirm those effects.
The lecturer covers the general principle and the algorithms of image sampling and quantization, color, point operations, segmentation, morphological image processing, linear/non-linear image filtering and correlation, image transforms, noise reduction, and pattern matching.
This course follows DP4 in the diplomat policies of the faculty.
By end of this course, you will be able to:
(1) understand and explain about the structure of a digital image
(2) understand and explain the general principle and the algorithm of image filtering and processing techniques
(3) understand and explain the effects obtained as a result of applying algorithms to an image.
You will be graded by your submitted reports (50%) and final examination marks (50%).
Reports are returned afterwards with comments.

Prior to each lecture, read the corresponding part of the textbook and presentation material carefully. This preparation requires more than 1.5hr.
If there is an assignment at the end of the presentation material, work on it (which would require another 1.5hr~).
We use GNU Octave as for programming language/environment.
