15 | 16 | ## 1.Import OpenCV 4.1 Module in AndroidStudio 3.4.1 17 | 1) Dowload OpenCV SDK from https://sourceforge.net/projects/opencvlibrary/files/4.1.0/opencv-4.1.0-android-sdk.zip/download 18 | 2) Clone this project. 19 | 3) Open Android Studio and import this project. 20 | 4) Build project. 21 | 5) From AndroidStudio top-menù select **New -> Import Module** and select your path to OpenCV sdk folder (i.e */where_opencv_saved/OpenCV-android-sdk/sdk*) and rename module as OpenCV. 22 | 6) After load OpenCV module, re-build project. 23 | 24 | ## 2.Add OpenCV dependecies to your application 25 | After OpenCV module import: 26 | 1) From AndroidStudio top-menù select **File -> Project Structure** 27 | 2) Navigate to Dependencies and click on **app**. On the right panel there's a plus button **+** for add Dependency. Click on it and choose **Module Dependecy**. 28 | 3) Select **OpenCV** module loaded before. 29 | 4) Click Ok and Apply changes. 30 | 5) Build project. 31 | 32 | ## 3.How detection works: CameraActivity.java 33 | This activity is the core of application and it implements *org.opencv.android.CameraBridgeViewBase.CvCameraViewListener2*. 34 | It has 2 main private instance variable: a **net** (*org.opencv.dnn.Net*) and a **cameraView** (*org.opencv.android.CameraBridgeViewBase*). 35 | Basically has three main features: 36 | 37 | #### a) Load Network 38 | Load convolutional net from *\*.cfg* and *\*.weights* files and read *labels name* (COCO Dataset) in assets folder when calls onCameraViewStarted() using **Dnn.readNetFromDarknet(String path_cfg, String path_weights)**. 39 | **NOTE**: this repo doesn't contain weights file. You have to download it from YOLO site. 40 | 41 | 42 | #### b) Detection from camera preview 43 | Iteratively generate a frame from CameraBridgeViewBase preview and analize it as an image. Real time detection and the frames flow generation is managed by **onCameraFrame(CvCameraViewFrame inputFrame)**. 44 | Preview frame is translate in a Mat matrix and set as input for **Dnn.blobFromImage(frame, scaleFactor, frame_size, mean, true, false)** to preprocess frames. Note that **frame_size** is 416x416 for YOLO Model (you can find input dimension in *\*.cfg* file). We can change the size by adding or subtracting by a factor of 32. Reducing the framesize increases the performance but worsens the accuracy. 45 | The detection phase is implemented by **net.forward(List\ results, List\ outNames)** that runs forward pass to compute output of layer with name *outName*. In *results* the method writes all detections in preview frame as Mat objects. 46 | Theese Mat instances contain all information such as positions and labels of detected objects. 47 | 48 | 49 | #### c) Draw bounding-box and labelling 50 | Performing **Non Maximum Suppression** by YOLO, in **List\ results** are stored all coordinates of optimal bounding boxes 51 | (the first 4 numbers are [*center_x, center_y, width, height*], followed by all class probabilities). *classId* is the corresponding index for label of detection in COCO Dataset list *className*. 52 | 53 | ## TO DO 54 | - [ ] Full screen JavaCameraView portrait mode 55 | - [ ] Speed up JavaCameraView 56 | - [ ] Add model chioce 57 | 58 | 59 | 60 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/app.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 24 | 25 | 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 "org.med.darknetandroid" 8 | minSdkVersion 26 9 | targetSdkVersion 29 10 | versionCode 1 11 | versionName "1.0" 12 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 13 | } 14 | buildTypes { 15 | release { 16 | minifyEnabled false 17 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 18 | } 19 | } 20 | } 21 | 22 | dependencies { 23 | implementation fileTree(dir: 'libs', include: ['*.jar']) 24 | implementation 'androidx.appcompat:appcompat:1.0.2' 25 | implementation 'androidx.constraintlayout:constraintlayout:1.1.3' 26 | testImplementation 'junit:junit:4.12' 27 | androidTestImplementation 'androidx.test:runner:1.2.0' 28 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' 29 | } 30 | -------------------------------------------------------------------------------- /app/build/generated/source/buildConfig/debug/org/med/darknetandroid/BuildConfig.java: -------------------------------------------------------------------------------- 1 | /** 2 | * Automatically generated file.
