Lecture Notes
Lecture Notes in Digital Image Processing
Lecture Notes: Lectures consist of lecture slides in pdf format and accompanying audio in realaudio format. Each slide has a button to activate the audio clip that presents that slide. You must download the audio clips and unzip to the same directory where you saved the pdf file to play the accompanying audio. Some examples and homework utilize matlab (you may also try octave).
Comments and Bugs: I will appreciate comments as well as reports of bugs and mistakes here. Please use the subject line "Regarding DIP lecture notes". Thank you.
Tutorial:
Lecture outline: Outline of the lecture is on the left (see image below).
Audio: Clicking on the blue arrow on the top left will launch the realplayer to play the audio clip for the slide.
Yellow note boxes: Click them for some extra information.
Purple text: Click to link to definitions, equations, or references in the document related to the text (once linked the right mouse button should open a window which will allow you to go back where you came from).
Source: I have also included the latex source together with the images used to generate the pdf slides (you will need the program dvipdfm to convert dvi files to pdf). The latex sources contain pdf specials to enable launching realaudio from the pdf file (\ralink macro), to enable slide titles to appear in the pdf outline at various depths (\mytitle, \mysubtitle, \mysubsubtitle), to enable pdf note boxes such as the one shown in the tutorial (\mynote macro), and finally to enable linking within the pdf document (\dest and \link macros). For pdf specials please consult the dvipdfm manual as well as Adobe's pdf specification document.
