Here’s a cute trick the nyt uses for their slideshows to prevent users from saving images locally (Note: I am not encouraging this). If a user right clicks an image and selects “save as…” the image which gets saved is pixel.gif, which is garbage (example here). By viewing the page source, we can figure out why that happens:
<div class="figure module">
<div class="image">
<div class="centeredElement" style="background-image:
url('http://graphics8.nytimes.com/images/2010/08/04/
arts/design/04maker-ss-slide-GSQJ/04maker-ss-slide-
GSQJ-slide.jpg');width:333px; height:500px;">
<img width="333" height="500" src="<a href=
"view-source:http://graphics8.nytimes.com/images/
misc/pixel.gif">http://graphics8.nytimes.com/images/
misc/pixel.gif</a>" />
The image we want is the background, covered by pixel.gif. Tricky.

Now it can find goal posts! And its supposed to be able to shoot the ball into the goal… that is, after it finds the ball and the posts and lines up properly, which is proving to be tricky…
We convert the RGB picture it takes into YUV, and then analyze that, so it filters the color of the tennis ball better. Then, we use this awesome time-saving library called CCAnalysis to find the middle of the posts and the ball, we turn until the ball is inbetween the posts, and then… we shoot!!

So maybe I’ll start weblogging about what I do 10 hours/day…. play with computers! Google thinks weblogging is spelled wrong, and suggests “we blogging, backlogging and flogging” but recognizes its abbreviation — blogging!
