Canon bounces back with the EOS 1D Mark IV

Canon didn't allow Nikon to enjoy the limelight for too long after all, announcing the forthcoming release of its new EOS 1D Mark IV professional D-SLR camera before the fanfare that accompanied Nikon's D3S had even died down. As well as slightly improving the huge ISO range of the D3S, Canon looks to have seized the opportunity to further raise the standard a little by opting for a 16.1 Mp sensor and 1080p high definition video.

Memory chips could lead the way to gigapixel cameras

Image sensors embedded in digital cameras are expensive, and issues with their circuitry limit the quality and resolution in the pictures they produce. Now a research group from the Netherlands believes a cheaper solution could be right before our eyes - the team's "gigavision" technique exploits the high light sensitivity of memory chips to produce inexpensive gigapixel sensors that perform very well, especially in extreme lighting conditions.

Using radio waves to ‘see’ through walls

University of Utah engineers have developed a system that uses a wireless network of radio transmitters to track people moving behind solid walls. They say the system could help police, firefighters and other emergency services capture intruders, and rescue hostages, fire victims or elderly people who fall in their homes by letting them know where to focus their attentions. The engineers’ system uses radio tomographic imaging (RTI) to “see”, locate and track people or objects in an area surrounded by inexpensive radio transceivers that send and receive signals.

That's him, officer - the Police sketch artist evolves

Human memory is a notoriously unreliable thing that can be easily influenced. That’s good news for criminals and bad news for law enforcement agencies that often rely on eyewitnesses to provide a description of a criminal. Around the world, law enforcement agencies employ sketch artists to piece together faces in a process similar to assembling a Mr. Potato Head toy. The witness describes key features, such as hair length, nose size or sharpness of the chin, and the artist combines them to create a likeness. Research into psychology suggests that this kind of method doesn’t take into account how the memory actually works, so researchers have developed new software that helps witnesses recreate and recognize suspects using principles borrowed from the fields of optics and genetics.
