New Morphological Features for Grading Pancreatic Ductal Adenocarcinomas

Algorithm 2

PIP_Detection_For_Atypia_ Amplitude_Signature  (amp_list, T).

Input: Atypia-Amplitude Signature   amp_list, Threshold for PIP detection T

Output: the sequence of the detected pip points pip_list

Method:

(1) m ←amp_list.length

(2) pip_list ← new List()           //initialize pip_list

(3) pip_list.add (amp_list.get(1))         //the first point of amp_list is added in pip_list

(4) Sub_PIP_Detection (1, m, amp_list, T, pip_list)   //pip  detection  is  performed at given range

(5) return  pip_list
