The CLOUDS is a software created for detecting the size of surfaces from which gases (or gas bubbles) evaporate. Most of the gases seem brighter against the background and they can be seen with a naked eye or can be filmed by cine-camera. The CLOUDS software requires two cameras filming the given object at one and the same time. The pictures of the object are saved as AVI-files, which are further used in the program. The program identifies the object in the same way as the human eye does it. The computer program operates in a field determined by 4 points chosen in advance.These points serve as a field for the two immovable cameras, develop the space and remove the perspective originating from the filming of the objects at an angle. The points mentioned serve also for connection of the two objects in the memory of the computer and for creation of virtual space. This stereo effect facilitates the correct identification of the surface from which the gases come out. The program is completely automated and requires only initial setting up of the plane parameters. The CLOUDS?s output is very flexible and allows connection with every program for further drawing or processing of the results.

Loading and some general requirements

The product is a short EXE program, consisting of several modules. CLOUDS is loaded, using 3 diskettes in WINDOWS 95- or WINDOWS NT-media. The installation of CLOUDS only, is not enough to use the program. This program is only a bridge between the application "Source" (AVI 1 file and AVI 2 file) and the application "Receiver" (Excel, Word, Origin, ...)
 

The idea of CLOUDS...

Operation in automatic regime...
After processing the first few frames manually it is possible to turn to automatic mode.

Processing of the result...
The result is shown as a column. The figures give the result in pixels, in a field 400/250. The real result is obtained by simple calculation.

Compatibility and scope of applicability...
This program is created to detect smoke upon surfaces, but the program can also be used to detect any object which intensity differs from the surrounding background. The operating raster of the system is 400/250 pixels and can not be changed. This raster is good enough to detect objects and the operating computer?s time is also quite acceptable. High quality pictures decrease to a greater degree the time for system tuning.
CLOUDS is very flexible according to the ?Source? and ?Receiving? applications. The ?Source? could be provided by any AVI files and any spreadsheet program could be used as Receiving application.
CLOUDS considers only the brightness of the objects and the easy finding of the 4 points determining the operating surface.

Some examples ...
The program CLOUDS can see the objects only using pixels intensity. The colors are invisible. This picture represents a piece of AVI file, demonstrating how CLOUDS see objects. There is no colored picture and you will see that objects become obscure.
