Iris Recognition Program

hello everyone,
i found an interesting iris scanning project on github,(GitHub - e-radu/irisRec: iris recognition for zybo). However i cant get it running.
i have cracked my head around this program for a month but i cannot see it working. Please help me make this project run on Linux machine

What exactly are the difficulties that you faced when attempting to get it running?

first, when adding a user to the database. it will print segmentation done...encoding done but it will not add the image to the database. i.e it will not print "4 images added to the database.

second,when comparing a user to the database,it will print segmentation done...matching done. but it will not print that the user is in database or user is not in database which is its main use.

lastly, i found that int support_grbg = 0 has been initialized to 0 but later has been assigned value of 1.

Code:

---

int support_grbg10 = 0;

        struct v4l2_fmtdesc fmtdesc = {0};
        memset(&fmtdesc, 0, sizeof(fmtdesc));
        fmtdesc.index = 0;
        fmtdesc.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
        char fourcc[5] = {0};
        char c, e;
        printf("  FMT : CE Desc\n--------------------\n");
        while (0 == xioctl(fd, VIDIOC_ENUM_FMT, &fmtdesc))
        {
                strncpy(fourcc, (char *)&fmtdesc.pixelformat, 4);
                if (fmtdesc.pixelformat == V4L2_PIX_FMT_SGRBG10)
                  support_grbg10 = 1;
                c = fmtdesc.flags & 1? 'C' : ' ';
                e = fmtdesc.flags & 2? 'E' : ' ';
                printf("  %s: %c%c %s\n", fourcc, c, e, fmtdesc.description);
                fmtdesc.index++;
        }

So it's a project over 3 years old with a single commit.

Most likely, the author just dumped it on GitHub for safe keeping, then either forgot about it, or found something else to do.

I guess everything that it doesn't do means code hasn't been implemented yet.

If you're looking to get up and running quicker than doing everything yourself, I would suggest finding a more mature project.

Actually,he implemented it on Iris Recognition on Zybo: 12 Steps . But i cant make it work on my side

What arguments do you pass to the program when you run it?

It appears to accept a couple of parameters.

By default, it reads "/dev/video0"
- Does this device exist on your system?
- Are you able to access it as a 'normal' user, or do you have to be a 'root' user?

Try to be more informative than "it doesn't work".

Eg.

Code:

---

$ gdb -q ./irisRec_v1
Reading symbols from ./irisRec_v1...done.
