Steve on Image Processing

Digital Forensics

The March 2009 issue of IEEE Signal Processing Magazine landed in my mailbox last week. It contains a special section on digital forensics. The special section is jam-packed with image processing, including these articles:

  • Image Forgery Detection
  • Digital Image Forensics
  • Component Forensics
  • Identifying and Prefiltering Images
  • Printer and Scanner Forensics
Fascinating stuff! I look forward to reading it. Perhaps I'll find some good blog material.

    Steve, yes photo forensics is fascinating stuff. A few years ago Robert Fiete, a former classmate of mine (Univ Arizona, Optical Sciences Center mid-80’s), published this easy-reading, overview article in SPIE’s magazine. It’s fascinating reading.

    Mark—Thanks for the link.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
