This repository includes the work I have done during my Summer Internship of 2017. I have Conducted my Summer Internship in METU Computer Engineering Department Image Processing Lab under the supervision of Asst. Prof. Dr. Emre Akbaş. During the project, I created an Ionic App called ImageCaptioner that takes as an input a picture, either taken in advance or at that moment, and upon uploading, it returns the reponse that what is inside the picture to the user.
To do this, a web server to handle the post requests was needed. I made a server using Node.js and connected it to department's server machine in which the algorithm that recognizes the contents of the picture was executed and the reply was sent back to sender. Here are some pictures from the app.
The client is coded using Ionic Framework Version 3.5. Therefore, Ionic needs to be installed. To install Ionic Framework, one needs to install Node.js as well. To install Node.js, on the Terminal,
$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
$ sudo apt-get install -y nodejs
Afterwards install Cordova by typing on the terminal
$ sudo apt-get install -g cordova
Then install Ionic.
$ sudo npm install -g ionic
Afterwards, download and install Android Studio by following the instructions in Android Website
Then install Oracle JDK and Android SDK
Set your ANDROID_HOME and point to Sdk folder and update PATH by starting gedit ~./profile and adding these lines to the bottom:
export ANDROID_HOME=”$HOME/Android/Sdk”
export PATH=”$PATH:$ANDROID_HOME/tools”
export PATH=”$PATH:$ANDROID_HOME/platform-tools”
Afterwards go to project directory and add Android Platform.
$ ionic cordova platform add android
Now that Ionic is installed, client can be downloaded from this repository and be built or emulated after the necessary plugins are installed. Note that normally you need to import installed modules to src/app/app.module.ts. However since in this project they are already present, only installing is needed.
$ ionic cordova plugin add cordova-plugin-camera
$ npm install --save @ionic-native/camera
$ ionic cordova plugin add cordova-plugin-file
$ npm install --save @ionic-native/file
$ ionic cordova plugin add cordova-plugin-file-transfer
$ npm install --save @ionic-native/file-transfer
$ ionic cordova plugin add cordova-plugin-filepath
$ npm install --save @ionic-native/file-path
Finally now that everything is ready, the project can be built and/or emulated.
$ ionic cordova build android
$ ionic cordova emulate android
The Node.js Server is coded using Express. Therefore having installed Node.js, Express needs to be installed.
$ sudo apt-get install node-express
$ sudo npm install -g express
Afterwards, some modules need to be installed in order for server to operate.
Since the necessary modules are present in package.json file, all of them can be installed by npm install command.
$ npm install
When the plugins are installed, the server can be started by going to server's directory in terminal and typing the command:
$ node app.js
