Hi, i want to recognize the dot number of the image, just like
the image may be scaled, rotated, but the dot number is unaltered.
I have used the simpleblob detector to extract the small circular blob, showing
as you can see, for some image, the circular blob may be extracted perfectly, while badly for others.
For dot number recognition, i used bag of words object category framework, 'SimpleBlob' detector, 'SIFT' descriptor and SVM classifier are used, but the result is not very good.
So is there any other method suitable for my problem?
