-------------------------------------------------------------------------------- 1 | # FaceRecognition 2 | This is an Android application for face recognition. The main purpose of this project is to serve as basis for others who want to deploy their deep learning models to an Android application. 3 | 4 | ## Face Detection 5 | The face detection package was taken from [this repository](https://github.com/vcvycy/MTCNN4Android). It uses the MTCNN model for face detection and it is runned using an old TensorFlow API (TensorflowInferenceInterface) for Android. 6 | 7 | ## Face Recognition 8 | The face recognition model used is FaceNet. It was obtained through the instructions in [this repository](https://github.com/jiangxiluning/facenet_mtcnn_to_mobile). The model is runned using the TensorFlow Lite API. 9 | 10 | ## Usage 11 | If you want to use the code of this project in your own application, then follow the steps below: 12 | 13 | - Copy the model files (mtcnn_freezed_model.pb e facenet.tflite) to your "assets" folder. 14 | - Add the following code to "build.gradle": 15 | ``` 16 | android { 17 | aaptOptions { 18 | noCompress "tflite" // Prevents compression of tflite files 19 | noCompress "lite" 20 | } 21 | } 22 | 23 | dependencies { 24 | implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly' // Official API 25 | implementation 'org.tensorflow:tensorflow-android:+' // Old API (TensorflowInferenceInterface) 26 | } 27 | ``` 28 | - Copy the packages FaceRecognition and FaceDetection. 29 | - To calculate the similarity score between two faces do as follows: 30 | ```java 31 | 32 | FaceNet facenet = new FaceNet(getAssets()); 33 | 34 | // cropFace returns null if no face could be detected in the provided image 35 | Bitmap face1 = cropFace(bitmap1); 36 | Bitmap face2 = cropFace(bitmap2); 37 | 38 | if (face1 != null && face2 != null) { // To make sure both faces were detected successfully 39 | double score = facenet.getSimilarityScore(face1, face2); // Euclidian distance between the face descriptor vectors 40 | } 41 | 42 | facenet.close(); 43 | ``` 44 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/app.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 10 | 11 | 12 | 13 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | 131 | 132 | 133 | 134 | 135 | 136 | 137 | 138 | 139 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 29 5 | buildToolsVersion "29.0.0" 6 | defaultConfig { 7 | applicationId "com.example.facerecognition" 8 | minSdkVersion 15 9 | targetSdkVersion 29 10 | versionCode 1 11 | versionName "1.0" 12 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 13 | } 14 | 15 | aaptOptions { 16 | noCompress "tflite" 17 | noCompress "lite" 18 | } 19 | 20 | buildTypes { 21 | release { 22 | minifyEnabled false 23 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 24 | } 25 | } 26 | compileOptions { 27 | sourceCompatibility = '1.8' 28 | targetCompatibility = '1.8' 29 | } 30 | } 31 | 32 | dependencies { 33 | implementation fileTree(dir: 'libs', include: ['*.jar']) 34 | implementation 'androidx.appcompat:appcompat:1.0.2' 35 | implementation 'androidx.constraintlayout:constraintlayout:1.1.3' 36 | testImplementation 'junit:junit:4.12' 37 | androidTestImplementation 'androidx.test:runner:1.2.0' 38 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' 39 | 40 | implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly' // New API 41 | implementation 'org.tensorflow:tensorflow-android:+' // Old API 42 | } 43 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *;
