Hello Ridhima,

I understand that the requirement is to use the collection of .M files published in File-Exchange with title “Iris segmentation using Daugman's integrodifferential operator” to highlight the iris in the image of an eye.

Here are the steps to achieve this:

• Open the File Exchange link and click the download button to get a .ZIP file.
• Unzip the file into the desired folder. This will create a folder named Integrodifferential_operator. Add this folder and its subfolders to the MATLAB path.
• Read the image for iris localization. This can be done using the following command:

    img = imread("eye.jpg"); 

• Call the ‘thresh’ function, providing the image as the first input, the minimum iris radius as the second input, and the maximum iris radius as the third input.

    [ci,cp,out] = thresh(img,30,100); 

• The output image will be stored in the ‘out’ variable. Use ‘imshow’ to view the image.

    imshow(out); 

• Below is a screenshot of the output image.
