initial model to detect iris

[ayushanand18]

Note: This issue is for my reference as a note-keeper and at the same time for all of you to show me the right direction whenever I go wrong.

Overview

Direction and methods to detect iris while capturing images of the iris.

Methods

• [x] OpenCV's HoughCircle() Transform to detect circles in image. Might be less accurate but the fastest and easiest solution, ~Need to experiment it.~ Ref
  • Tried and tested it. This is heck slow!
• [x] OpenCV's Haar Cascade Classifier. Tried using it but it couldn't detect eyes without pair. ~Fast but unusable~
• [x] Using a custom OpenCV based Script (edge detection, contour detection, Circle Hough Function). On it! trying hard to translate it to our use.
• [ ] Custom Trained ML Model. Requires access to data (CASIA, UBIRIS are not public but open.) Requires some efforts and fine-tuning. Not using this method until all other non-ML image processing tools get over.

• This stackoverflow question might be helpful for us.
• This paper also but at a later stage.

Update: Finally got an algorithm that is

• blazing fast
• detects pupil very accurately Now, trying to translate it into iris detection - all without ML.

@adarsh500 can you help us with understanding this project https://github.com/Pradyuman7/TrackEyes/blob/master/app/src/main/java/com/pd/trackeye/MainActivity.java? or if it is even useful to us.
