Number of pixels in sets of SBK

[zacniewski]

Hi Michal,
In article it is written: "The pixel p is a SBK if there is a contiguous circle segment of at least 6 pixels which are darker (or brighter) than the pixel p ...". Which means equals or greater (>=) in my opinion. But in the text above is the sign '>', I mean Pd > 6 or Pb > 6. What is the right answer?

Hi Artur,
the code is well behind the paper ( = number of modifications which are not described in the paper, such as number of pixels / corner checking). (we are using it for many tasks such as ant tracking wires detection), so some of of the modification comes from non/text problems, and we commit them if it does not harm performance on ICDAR 2013/Focused Scene Text/ Born Digital task.

Right answer is: plot ROC curves on your dataset and pick the best.
