There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement. You (or your employer) retain the copyright to your contribution; 10 | this simply gives us permission to use and redistribute your contributions as 11 | part of the project. Head over to to see 12 | your current agreements on file or to sign a new one. 13 | 14 | You generally only need to submit a CLA once, so if you've already submitted one 15 | (even if it was for a different project), you probably don't need to do it 16 | again. 17 | 18 | ## Code reviews 19 | 20 | All submissions, including submissions by project members, require review. We 21 | use GitHub pull requests for this purpose. Consult 22 | [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more 23 | information on using pull requests. -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | 2 | Apache License 3 | Version 2.0, January 2004 4 | http://www.apache.org/licenses/ 5 | 6 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 7 | 8 | 1.

(Don't include 184 | the brackets!) The text should be enclosed in the appropriate 185 | comment syntax for the file format.

We show you emojis 🍌 ⏰ ☕️ 📱 and you have to find those objects in the real world before your timer runs out 🏆 👍. 4 | 5 | Find out how we built this experiment by reading our [article](https://medium.com/tensorflow/a-look-at-how-we-built-the-emoji-scavenger-hunt-using-tensorflow-js-3d760a7ebfe6) on the Tensorflow blog or try it for yourself at [g.co/emojiscavengerhunt](http://g.co/emojiscavengerhunt). 6 | 7 | 8 | ## Development 9 | 10 | ```sh 11 | yarn prep 12 | ``` 13 | 14 | Running `yarn prep` will use yarn to get the right packages and setup the right folders. If you don't have [yarn](https://yarnpkg.com/lang/en/docs/install/) you can install it via homebrew (for Mac). If you’re already running node/npm with nvm (our recommendation) you can install yarn without node using `brew install yarn --without-node`. 15 | 16 | In order to start local development we also require the installation of the [Google Cloud SDK](https://cloud.google.com/sdk/downloads) and associated [App Engine Components](https://cloud.google.com/appengine/docs/standard/python/download). These are used for the local webserver and pushing to app engine for static site hosting. 17 | 18 | Once you have both installed you can run the local development server with: 19 | 20 | ```sh 21 | yarn dev 22 | ``` 23 | 24 | This task uses `watchify` to continually watch for changes to JS and SASS files and recompiles them if any changes are detected. You can access the local development server at `http://localhost:3000/` 25 | 26 | When building assets for production use: 27 | 28 | ```sh 29 | yarn build 30 | ``` 31 | 32 | This will minify SASS and JS for serving in production. 33 | 34 | ## Build your own model 35 | You can build your own image recognition model by running a Docker container. 36 | Dockerfiles are in `training` directory. 37 | 38 | Prepare images for training by dividing them into directories for each label 39 | name that you want to train. 40 | For example: the directory structure for training *cat* and *dog* will look as 41 | follows assuming image data is stored under `data/images`. 42 | 43 | ``` 44 | data 45 | └── images 46 | ├── cat 47 | │   ├── cat1.jpg 48 | │   ├── cat2.jpg 49 | │   └── ... 50 | └── dog 51 |    ├── dog1.jpg 52 |    ├── dog2.jpg 53 |    └── ... 54 | ``` 55 | 56 | Once the sample images are ready, you can kickstart the training by building and 57 | running the Docker container. 58 | 59 | ``` 60 | $ cd training 61 | $ docker build -t model-builder . 62 | $ docker run -v /path/to/data:/data -it model-builder 63 | ``` 64 | 65 | After the training is completed, you'll see three files in the 66 | `data/saved_model_web` directory: 67 | 68 | - tensorflowjs_model.pb (the dataflow graph) 69 | - weights_manifest.json (weight manifest file) 70 | - group1-shard\*of\* (collection of binary weight files) 71 | 72 | They are SavedModel files in a web-friendly format converted by the 73 | [TensorFlow.js converter](https://github.com/tensorflow/tfjs-converter). 74 | You can build your own game using your own custom image recognition model by replacing 75 | the corresponding files under the `dist/model/` directory with the newly generated ones. 76 | 77 | The training script will also generate a file called `scavenger_classes.ts` 78 | which works in conjunction with your generated custom model. 79 | You need to replace the file at `src/js/scavenger_classes.ts` with this newly 80 | generated `scavenger_classes.ts` file so that the labels of your model match 81 | with the trained data. 82 | After replacing the file you can run the build script normally to test your 83 | model in a browser. See the README file for information on running a preview 84 | server. 85 | 86 | Update the game logic in `src/js/game.ts` if needed. 87 | 88 | ``` 89 | 90 | ## License 91 | 92 | Copyright 2018 Google LLC 93 | 94 | Licensed under the Apache License, Version 2.0 (the "License"); 95 | you may not use this file except in compliance with the License. 96 | You may obtain a copy of the License at 97 | 98 | https://www.apache.org/licenses/LICENSE-2.0 99 | 100 | Unless required by applicable law or agreed to in writing, software 101 | distributed under the License is distributed on an "AS IS" BASIS, 102 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 103 | See the License for the specific language governing permissions and 104 | limitations under the License. 105 | 106 | ## Credits 107 | 108 | This is an experiment and collaboration between Google Brand Studio and the [PAIR](https://ai.google/pair/) teams at Google. 109 | 110 | ## Final Thoughts 111 | 112 | This is not an official Google product.
