Watermarking of Scalable Video, Citations

I just became aware of a book chapter authored by Dan Grois and Ofer Hadar, Recent Advances in Watermarking for Scalable Video Coding, Watermarking - Volume 2, Intech Open Access, ISBN: 978-953-51-0619-7, edited by Mithun Das Gupta (DOI 10.5772/37543).

The chapter summarizes large parts of my work: nice, thanks. On the other hand, three figures from my papers are redrawn and reproduced and several sentences are restated in full (and cited).

ActionScript with Linux

Some ActionScript code ( which displays a triangle and a rotating rectangle:

_root.createEmptyMovieClip('triangle', 1);

with (_root.triangle) {
  lineStyle(10, 0xff0000, 100);
  moveTo(200, 200);
  lineTo(300, 300);
  lineTo(100, 300);
  lineTo(200, 200);
var r:MovieClip = createEmptyMovieClip('rectangle', 2);
r.beginFill(0xcc00cc, 100);
r.moveTo(20, 20);
r.lineTo(140, 20);
r.lineTo(140, 140);
r.lineTo(20, 140);
r._x = 230;
r._y = 190;
r.onEnterFrame = function() {
  this._rotation += 5;

Compile it using ming (a library for generating Macromedia Flash files, .swf):

makeswf -r 12 -v 9 -o triangle.swf
where -r specifies the frames-per-second and -v gives the Flash format/version to create (up to 9 is supported).

Finally, embed the scary Flash thing:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase=",0,0,0" width="550" height="400" id="home" align="">
<param name="movie" value='/as/triangle.swf'>
<param name="quality" value="high">
<param name="bgcolor" value="#ffffff">
<embed src='/as/triangle.swf' quality="high" bgcolor="#ffffff" width="550" height="400" name="home" align="" type="application/x-shockwave-flash" pluginspage="">

Here's the code and html.
