How to configure multiple images in mock MDS?

If you want to use the registration client with mock MDS to create IDs with distinct face images, refer to the steps below.

What is the need for this?

This will be needed when real devices are not available/integrated with the registration client and one wants to create test data for the demo of the registration client.

Steps

1. Have a set of photos you wish to use ready. They should be in jpg format.

2. Resize the photos to 240 X 320 pixels (width X height) and save them in jpg format using tools like Microsoft Paint

3. Convert the jpg image to jp2 format. One can use a tool like IrfanView for this.

4. Convert jp2 to iso format. You can use bio-utils from Mosip to perform the same

   • Clone bio-utils from Github and build it

   • Place the jpg image (ex: face1.jpg) in the folder bio-utils-develop\test\target\BiometricInfo\Face

   • Update the run_encoder_face.bat file with the image name as shown below and save the file.

   • Open

     

   • Run run_encoder_face.bat file. It will generate a ‘face1.jp2.iso’ file in the folder bio-utils-develop\test\target\BiometricInfo\Face

   • Optional: One can also use the BioCTS tool to verify the iso file generated above.

5. Use the ISO image in the mock MDS

   • There are 2 ways to do it:

     • Option 1: Create a separate profile for each user/image

       • Create a folder 'Profile1' under MDS/Profile

       • Rename the face1.jp2.iso file to Face.iso and copy it to the MDS/Profile/Profile1 folder. Also, copy biometric images for other modalities from the default folder into Profile1.

       • Many such profiles can be created as per requirement.

       • Set the profile being used in mock MDS using postman before capturing biometrics in the registration client as shown below

       • Open

         

       •  

     • Option 2: Reuse the default profile data and replace the Face.iso image every time

       • For every enrollment, replace the Face.iso image in the default profile with a new image of the same name

       • Restart the MDS

6. Once done now you are ready to use the regclient and capture the face image, the new image will appear in the registration client during enrollment.
