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.
