READER FEEDBACK...
A reader asks...
"Got any graphic tips for us?"
Glad you asked. Did you look at the Daily Pic above? Well, it's a composition of two photos.
There were several challenges involved in merging the two photos. The skin tones (due to lighting) were very different. The daughter had to be in back of some objects in the parent pic, yet be in front of other objects in the parent pic.
Tomorrow I'll give you a step by step description of how I arrived at the final composition. Until then, look at all three pics and decide how you might go about merging the two photos.
ON THE LIGHTER SIDE...
When computer programmers are hungry they take mega-bites.
WEEKLY IN DEPTH...

Security or Invasion of Privacy?
Officials used video surveillance to scan images of fans as they passed through turnstiles to watch the Super Bowl last weekend.
Thousands of football fans were subjected to a "computerized police lineup" at America's biggest sporting event last weekend, as police used cutting-edge technology to scan the crowd for pickpockets and terrorists.
Like surveillance cameras in convenience stores, at
cash-dispensing machines, ATMs, or on street corners, the cameras installed for the Super
Bowl game between the Baltimore Ravens and the New York Giants captured images of
people in a public place.
But unlike most video surveillance systems, which store the images on tape,
the cameras were connected by cable to computers that scanned the images, instantly dissecting facial
features and comparing them to a digital database of known criminals and terrorists.
Signs outside the stadium warned fans that they were under video
surveillance, police said.
The video system, which uses biometric technology to compare
facial features such as the size of a nose, the set of a brow, or the cut of a jaw,
was offered to the Tampa Police Department by Graphco Technologies, a Pennsylvania-based
database and "knowledge management" firm.
The test project compared images from the video cameras to a
relatively small database of about 1,700 faces -- including crooks ranging from pickpockets to domestic terrorists --
assembled from FBI and police files.
Future uses would hopefully include larger databases of tens
of thousands of criminals.
