IPhone will be able to determine the quality of meat and air photos

Imagine a situation when you come on the market, meat photographed and immediately receive reliable information about its freshness. Or by making landscape photography, we learned all about the concentration of harmful aerosols. It sounds fantastic, but the technology already exist and are being tested.
Technology to determine the quality of the meat from a photograph developed by Russian scientists from the Laboratory of Technological Design Institute of Scientific Instrument Engineering of SB RAS. According to the doctor of technical sciences Irina penlight, the technology is able to distinguish thousands of imperceptible shades of red eye and to determine the freshness of meat.
Meat color pigments due complex proteins. The fresh raw materials under the influence of oxygen, they presented dark red myoglobin, bright red and brown oxidized oxymyoglobin metmyoglobin, which pass into each other. Over time, the second one indicating the freshness of the product, by reaction with oxygen and becomes the third gives the product an unattractive earthy or dark brown color.
That is why the sausages are always stained in pale pink color. The technology has already been tested, and will enter the market as soon as the base reference samples collected meat. The advent of applications for the iPhone depends on the efficiency of entrepreneurs who first write Irina penlight.
Using landscape photographs soon can determine the air quality. Scientists at the University of Rochester have developed an algorithm by which to determine the concentration of dust and other airborne particles in amateur photography. A detailed overview of the algorithm (in English) can be downloaded at arXiv.org.
The authors use the algorithm convolutional neural network and standard color correction techniques to "highlight" dust on photos, and then compare them to environmental monitoring data. At the moment, the accuracy of the results ranged from 40% to 89%.
And another iPhone application offering scientists from the Moscow Physical-Technical Institute, where he developed a nanophotonic biosensor for diagnosing cancer at an early stage. Its dimensions are so small that they easily allow to build it into a smartphone or smartwatch. On the same chip of several millimeters can be assembled together to several thousands of sensors configured to detect different particles or molecules. The sensor analyzes the chemical composition of substances in blood and determines markers of viral diseases such as HIV, hepatitis, herpes, and others.
Of course, it is not necessary to wait for the above possibilities in the next year or two. But who knows, maybe a couple of years really any smartphone is also a mini-lab in your pocket.
