2. Readings: Week 2, Image and Signal Processing and Image Compositing

Primary Readings: Shirley Ch. 4 and Interactive Tutorials, compositing tutorials

Read Shirley, Chapter 4. Sections 4.1-4.4 will give a good overview of the subject. We won't go into all of the detail of Section 4.5 in class, but some of the concepts will be important. You will need to understand convolution, filtering, aliasing, and how sampling can lead to aliasing.

I strongly recommend that you look at some of the interactive tutorials.

There are some in the Brown University Exploratories. In the Signal Processing Section, they have things to allow you to play with convolution and filtering (as well as some color things that we'll get to later). The convolution has some issues (read the directions carefully), but the discrete convolution(again, pay attention to the instruction) will be helpful. The special function convolution applet is probably better than the regular one (and it doesn't seem to have the same bug). The two box convolution is pretty simple, but can help if you're just not getting convolutions. The nyquist limit applet is really good for seeing how aliasing happens.

The "Optical Microscopy Primer" also has some really nice interactive tutorials, although their examples are more geared towards microscope images. Many are relevant (Spatial Resolution,Sharpness Adjustment (notice how sharpening introduces ringing). The Convolution Kernels demo will let you play with various kernels, ... This is a great resource - you might want to come back later in the semester to try out some of the other filtering types!

There are many basic signal processing tutorials out there. This one will help you with convolutions.

(alternate) Sampling theory is one of those things you might want to read about several times before you "get it." A great tutorial is Pat Hanrahan's Notes, although they are a bit mathematical. Mike Gleicher's tutorial on The Intuitions of Signal Processing are written for an application other than image processing, but cover the 1D material.

For image compositing, Alvy Ray Smith, "Image Compositing Fundamentals", (page 1-6 till the end of "premultiplication problems" required; others optional) and Tom Porter and Tom Duff, "Compositing Digital Images" (optional) are good references.

1. Readings, Week 1, Preliminaries

Primary Readings: Shirley, Chapters 1, 2, and part of Chapter 21 (pp. 477-486)

Chapter 2 reviews some high school and collage math concepts that will be often used in the class.

Chapter 21 covers human vision more than what we discussed in class. There is also a good tutorial Elements of Early Vision for Computer Graphics by Jim Ferwerda. Its available on his web page.
