About the advancing of computing

When we are talking about that in the 1970s or 1980s the error level of some analyzing program was 90% or even 99% and now the error level has been dropped to the level of 70-80% we must ask why this has been happening?  The reason for that is that there were fewer data at that time, and the data that was input in the computer was imputed by highly trained professionals, so that means that it was pre-processed. Today the mass of data is huge in the comparison with the situation in the 1980s, and the thing is that the system will get the data straight from the sensors like surveillance cameras and thermometers, and that means that the crude information would send straight in the system.

When we are thinking about the situation, that some surveillance camera will follow the situation on the streets, we must realize that there are multiple variables, what must be separated by computer. If we want that system to react to the fights, we must realize that it must separate birds and animals from humans, and that process is very hard to program. The thing is that if the security guard looks at the screens, that person can automatically detect the fights, and send the police or other authorities to the place. Those cases can be that somebody drives careless or somebody starts to fight. And the problem is that those things happen always suddenly. That kind of situations is also the reason, why security cameras have been installed in public places.

But the computer doesn't know anything itself. Every parameter of how this system locates the thing, what needs reactions must program to the computer. Then the system will notice if there is something to suspect, and after that, the surveillance camera will target that place for the security personnel. Those cameras can be used as the group, and they can locate every person in the streets by using triangular metering, and that makes possible to specify the place, where the thing was happening very sharply.

And then the system can follow the suspects. The thing in the security cameras is that they are meant for this kind of things. So the pictures what those systems give should render, that the persons cannot be identified or the system would show only the things, what are suspicious. Those things are unguarded bags, persons who are standing a long time in the train stops, or the movements like pushing somebody or hiding something under the clothes.

The thing is that this kind of information is needed for security guards. And that kind of systems deliver only information, what is needed for a decision. That means it would not follow any rockstars or persons, who are standing in the front of the magazine board. This means that the system filters unnecessary information for making the place safer.

The persons who make a decision of the actions in this kind of cases need only the information, what makes the situation dangerous, and if the thing is human, they need information is the person armed with firearms or does that person carry a bomb. In those cases that information must send to the authorities, what bring personnel what has the right stuff for handling those situations. And if the thing, what makes danger is the burning garbage can, would the best way to act in that situation take along the fire extinguisher and turn out the flames.
