I am trying to implement the algorithm specified in following paper(Sec 3: Ridge candidate extraction part).

http://ai.pku.edu.cn/aiwebsite/research.files/collected%20papers%20-%20palmprint/Feature%20extraction%20method%20for%20palmprint%20considering%20elimination%20of%20creases.pdf

But while proceeding there are lot of negative and very smaller numbers were generated while applying gaussian filter. Is there a predefined functions in OpenCV to use for this kind of operation?

Add some code and some details. – Miki Sep 11 '15 at 11:27
please look at research paper under given section. I am unable to post an image. – Shyam Sep 14 '15 at 14:36
in simply, 1. how to add gaussian function before DFT an image. 2. how to identify the location of the peaks. – Shyam Sep 14 '15 at 15:11
