Digital Image Processing

Content:

This week Dr. Liang gave us an overview of the basic knowledge of digital image processing. I take Jimmy’s course: Intro to Digital Image Processing as my selective course. Digital image processing is widely used in researches and our daily life. The digital camera is the result of digital image processing. There is a chip in the camera which can convert the light intensity into voltage and store the information in matrix. Actually, digital image processing deals with data in matrix, so besides the devices for obtain the image information, it is concerned with mathematics. Also, it needs the knowledge of programming, because it is the computer which does the mathematics for image processing. Usually digital processing is used to find the parts of images we are interested in such as the abnormal darkness in the CT image. The project we do for Jimmy’s course is to detect the contours in the image using an active contour model. It is interesting however we do it for a whole semester. The algorithm sounds amazing for me. It is sure that people who describe the algorithms must be intelligent and with high IQ.


Anyway, happy holiday to everybody~
