I was a beginner to Android development and Computer Vision back then. So don't expect a perfect code please. Over the years I updated the dependencies and converted it to Kotlin, while the business logic remained unchanged.\n\nNote: Originally I targeted min SDK 15 (Android 4), more architectures (\"mips\", \"mips64\", \"armeabi\") and OpenCV 3 with this project. Nowadays the repo uses newer versions. If you need to support older devices, then you can look back in the repo's Git history (app version 1.1 / Git tag 2)\n\n\u003cimg src=\"/screenshots/demo.gif\" alt=\"\" width=\"800\"/\u003e\nCopyright of the logo: The Coca-Cola Company\n\n### What is this repository for? ###\n* Uses the camera image to search for a specified template image within it via a feature matching approach using the OpenCV library. The detected object is marked with lines within the scene. This can be used to e.g. find a logo.\n* More computer vision projects at https://michaeltroger.com/computervision/\n\n### How do I get set up? ###\n* IDE: Android Studio  (tested with 2023.3.1)\n* Android SDK\n* Template image location: res/drawable (chooseable in MainActivity)\n\n### Template image ###\nUsed default template image:\n\n\u003cimg src=\"/app/src/main/res/drawable/coca_cola.bmp\" alt=\"\" width=\"200\" /\u003e\n\nCopyright of the logo: The Coca-Cola Company\n\n### Author ###\n[Michael Troger](https://michaeltroger.com)\n\n### Credits\n* The feature matching is based on this official OpenCV tutorial http://docs.opencv.org/2.4/doc/tutorials/features2d/feature_homography/feature_homography.html Unlike in this application their version is using OpenCV 2, C++ and is for use with regular static images\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmichaeltroger%2Ffeature-matching-android","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmichaeltroger%2Ffeature-matching-android","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmichaeltroger%2Ffeature-matching-android/lists"}
