課程概述

In this class you will learn the basic principles and tools used to process images and videos, and how to apply them in solving practical problems of commercial and scientific interests. Digital images and videos are everywhere these days – in thousands of scientific (e.g., astronomical, bio-medical), consumer, industrial, and artistic applications. Moreover they come in a wide range of the electromagnetic spectrum - from visible light and infrared to gamma rays and beyond. The ability to process image and video signals is therefore an incredibly important skill to master for engineering/science students, software developers, and practicing scientists. Digital image and video processing continues to enable the multimedia technology revolution we are experiencing today. Some important examples of image and video processing include the removal of degradations images suffer during acquisition (e.g., removing blur from a picture of a fast moving car), and the compression and transmission of images and videos (if you watch videos online, or share photos via a social media website, you use this everyday!), for economical storage and efficient transmission. This course will cover the fundamentals of image and video processing. We will provide a mathematical framework to describe and analyze images and videos as two- and three-dimensional signals in the spatial, spatio-temporal, and frequency domains. In this class not only will you learn the theory behind fundamental processing tasks including image/video enhancement, recovery, and compression - but you will also learn how to perform these key processing tasks in practice using state-of-the-art techniques and tools. We will introduce and use a wide variety of such tools – from optimization toolboxes to statistical techniques. Emphasis on the special role sparsity plays in modern image and video processing will also be given. In all cases, example images and videos pertaining to specific application domains will be utilized....

This is one of the best introductory courses on image processing. The lectures are very good and cover a large variety of topics.

The only thing that I didn't like about this course is that the homework problems do not cover all the content. The programming problems should be designed to be more challenging.

It's a great course although it'll probably make you go back to math very often but in the end you'll feel so happy because all the parts starts to make sense, I mean, you can understand mostly of what happens behind the scene (in digital video/image processing) and you read books to deepen your knowledge.

It is a very educative course. I like image processing and really enjoyed the course. The only suggestion that I like to give is to switch speaking pace or pitch time to time to keep the audience listening. It is hard to focus on a voice that does not (or try not to) have up and downs or excitement.

Professor Aggelos Katsaggelos and his team have greatly succeeded in manufacturing such magnificent material. It has been a very rewarding and motivating experience to learn directly from one of the best. I'm much grateful to everyone involved that devoted time to the making of this course.

The professor is of course very professional, specially, detailed. I learned not only the theories but also many interesting examples, which is much better than some of my teacher in the university. Now, I will go to the forum and search for some useful materials or comments.

Challenging and informative. Material was presented at the proper level, there was no dumbing down of this subject matter. You were never asked to take the instructor's word for anything. There was historical perspective and opened doors for new possibilities in my career.

The facilitator of the course with the staff is very talented. I am extremely fortunate and thankful at the same time to have found this course and I feel extremely obliged towards Coursera for providing students this opportunity to learn and benefit.

Thank you Coursera !

Great course to start learning about techniques used for image and video compression, enhancement and recovery. The coding question in the quizzes gives a toolbox for further exploration thus increasing the student's involvement in understanding the problem at hand.

I had good experience of learning image and video processing from the scratch to advanced level. I had training in playing with matlab code and excited to see my matlab processed images.This my first course in coursera and I have completed this 12 week course

This course was really helpful in understanding the difficult concepts of image and video processing. I highly encourage all the college students to take this course if they atre willing to improve their grades or are just interested in learning something new.

Best part was the last part. Nice course :) Please try Tensorflow, Scikit, Octive with lots of open source support and volunteers. Big issue was obscure hidden code in matlab routines svd, qrd etc coupled with extremely aggressive Licensing of Matlab :(

It is truly useful for those who need a FUNDAMENTAL of Digital Image & Video Processing, I mean, those who are interested in computer vision. It is the solid base brick of a huge building. Thanks for Prof. Aggelos K. Katsaggelos and NorthWest University.

I think the material touched the most important aspects of Image/Video Processing. I also enjoyed the Professor's patient and detailed style of covering the material. Quizzes were very helpful.

Some of the materials need fixes but other wise I enjoyed it.

As an amateur in this field, I realy enjoyed the course. It provides broad review of the subject. The mathematical details are not perfected, which caused me disorientation in week 7. Nevertheless, the main principles are very well explained intuitively.

Fascinating introduction to image processing. The course materiial is easier to follow if you have a solid background in mathematics and machine learning while basic programming skills will see you through the programming assignments.

Great Course and instructor is really knowledgeable. Every topic was explained with very basic concepts and adequate practical examples. I would wait for and advance course in Image Processing from the same instructor.

Tremendous amount of information. Instructor often says "this will become less mathematical from now on!" when in fact it doesn't. Exact literature references are missing for later chapters. Still very useful material.
