Hi All
Recently I was discussing with my friend about an issue that he was having in his company. He needs a very high speed counting system. So I suggested him to go for CIS sensor and FPGA. Do some Image processing and do the counting.
After some more discussion, I myself took up the challange and thought of delivering him the final product.

So here is the problem statement :

I need to count small objects (say a circular object with 50mm diameter). I will sense the object using a line sensor and create an image of it over time. Using FPGA I will do the reading from sensor and process the data and provide the exact count.

Now for counting, I'm still in the process of developing some algorithm. I thought of counting based on area. Say with some learning, I get a threshold value of area occupied by an object. And every time area goes beyond threshold, I increment the count. But there is a catch, Sometimes objects are in touch with each other. So in that case I was counting 2 objects as single quantity, since in image I was not getting a boundary for them.
Now as I think, I see that I should go on with something like contour matching or some other algorithm. So may be I can get help here towards finalising the algorithm.
