1: as shown in the position of pixel coordinate point collection, how to calculate the set continuous adjacent pixel number is greater than the set value, such as 6?
2: here is the communist party of China in 5 groups of pixels adjacent regions exist, continuous adjacent pixel number is 6;

You can see, there are at least the source code, test, there is a performance benchmark,

If it is a bunch of detection and maybe you first take a look at the opening and closing operation in image processing, I think it can screen out for target, can greatly accelerate the performance,
If it is the general cluster detection, can search image cluster analysis

Is the most direct/heavy, point by point, using the floodfill algorithm, calculation of connection number of pixels that point,
