Phansalkar
This is a modification of Sauvola's thresholding method to deal with low contrast images.
Phansalskar N. et al. Adaptive local thresholding for detection of nuclei in diversity stained cytology images. International Conference on Communications and Signal Processing (ICCSP), 2011, 218-220.
In this method, the threshold t is computed as:
t = mean * (1 + p * exp(-q * mean) + k * ((stdev / r) - 1))
where mean and stdev are the local mean and standard deviation respectively. Phansalkar recommends k = 0.25, r = 0.5, p = 2 and q = 10. In this plugin, k and r are the parameters 1 and 2 respectively, but the values of p and q are fixed.
default k value is 0.25. default r value is 0.5.
are there anyone to help me?? pleaseee
