The main target of the project is to find a way so that a color changing process can be said that it has attained a certain percentage of the model image. and also to ascertain that the process has attained almost or very near the condition of previous model image(i.e means it has attained the color within the limiting range ). The color of the color changing process may be of many color mixed and or a single color.
As for example say a process has many color but here the color counted is black and when the black color is about 80 % of the total different colors of that image that is taken as a model sample image. Now assume that a process is running and continuously being monitored, and when the percentage of black color of the process approaches from 70% or above or equals to 80% then it will be alarmed.
