LUNA ID size#

Total size#

The minimum size of LUNA ID that includes the face detection and OneShotLiveness estimation functionalities is:

LUNA ID for Android - 95 MB
LUNA ID for iOS - 115 MB

This size is the sum of the sizes of the required dependencies and neural networks used in LUNA ID. Knowing this information is crucial for understanding how each component influences the overall functionality and performance of LUNA ID.

The tables below provide the sizes of required dependencies, in MB.

FaceEngine	10 MB	6,8 MB	17,5	23,6
Flower	5,9 MB	4,4 MB	7,8 MB	9,3 MB
TrackEngine	5 MB	2,8 MB	24,1 MB	44,6 MB

In LUNA ID for iOS#

Dependency	Size
FaceEngine	40,4 MB
Flower	21,9 MB
TrackEngine	16,1 MB
LunaCamera	1,5 MB
LunaCore	1 MB
LunaWEB	1,9 MB

The table below provides the sizes that .plan files add to LUNA ID. For details about each .plan file and a functionality it covers, see Neural networks used in LUNA ID.

Measure LUNA ID size#

You can measure the size that LUNA ID adds to your app.

In LUNA ID for Android#

1․ Update build files to build separate .apk files for different platforms:

In the build.gradle.kts file:

android {
        ...
        splits {
            abi {
                isEnable = true
                reset()
                include("armeabi-v7a", "arm64-v8a", "x86", "x86_64")
                isUniversalApk = false
            }
        }
        ...
}

In the build.dragle file:

    android {
    ...

    splits {
        abi {
            enable true
            reset()
            include "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
            universalApk false
        }
    }

    ...
    }

2․ In Android Studio, run the Analyze APK utility.

3․ Open the build platfrom-specific .apk file (for example, armeabi-v7a) and see the size of the following files:

assets/data* folder
lib/{platform}/libTrackEngineSDK.so
lib/{platform}/libBestShotMobile.so
lib/{platform}/libflower.so
lib/{platform}/libMatchingKernel.s
lib/{platform}/libFaceEngineSDK.so
lib/{platform}/libwrapper.so
lib/{platform}/libc++_shared.so

Important notes#

Any other files are not parts of LUNA ID and are added by other dependencies of your app.
In the Analyze APK utility, there should be only one platform in the lib folder (for example, armeabi-v7a, arm64-v8a or any another). If there is more than one platform in this folder, then you are looking at a universal .apk file that includes all platforms. Go back a step and rebuild the app with splits.abi enabled.
