Let us learn how we can make a mobile app for image recognition. Also, learn and know how this recognition works.
Introduction The Mobile App For Image Recognition
How to Make a Mobile App for Image Recognition? Here are the following:
1: Download the SDK from the official website.
2: Install the SDK in your system.
3: Open Eclipse and click on File-> New-> Android Project.
4: Name your project and click Next.
5: Select the version of Android you want to build your app for. In my case, I’m making this app for Android 4.1 (API 16).
You can also select other versions as per your requirement. Click Next.
6: Select the Empty Activity template and click Next.
7: Give a name to your activity and click Finish.
For Additional Step
8: Open the AndroidManifest.xml file, which is located in app -> src -> main -> AndroidManifest.xml, and add the following code.
9: Open the activity_main.xml file, which is located in app -> src -> main -> res -> layout and add the following code.
10: Now we have to add the Projection class where we are going to write our image recognition algorithm. Open the MainActivity.java file, which is located in app -> src -> main -> java, and add the following code.
11: Finally, let us test our app in image recognition mode by adding a few images. Open the MainActivity.java file, which is located in app -> src -> main -> java again and add the following code at lines 25 to 30.
12: Just run your project and you will get a screen as shown below.
13: After running your app, select any image from your gallery. Also, you can or take a new image using your camera.
Next, click the Recognize image button to perform image recognition using Android Studio’s inbuilt OCR engine as shown below.
How Does This Image Recognition Work
Whenever you click the Recognize image button, the steps are performed from the following:
- This image is passed to the Projection class.
- The Projection class performs image recognition using the OCR engine.
- It reads and converts the characters in the image into words.
- These words are then converted into sentences.
- Finally, these sentences are displayed on a screen as shown below.
Therefore we can conclude and for the future scope. This article teaches you how to make a mobile app for image recognition using Android Studio’s inbuilt OCR engine.
So the above application is good to use any time you want to recognize an image directly. It is from your mobile phone without going for any other external applications or websites.
Moreover, this way you can easily make an application for many useful purposes. Such as identifying texts from images and making a shopping list.
Also, It is based on images or recording videos of people with their names, etc. So, this application can be used for various purposes.
For example, you can use it as an alternative to other image recognition software. That is the Google Goggles and much more applications.
Also, you can create a mobile application with this inbuilt OCR engine and sell it on PlayStore and Amazon App store. You can add more features like sharing the recognized text via any other messaging or social media app or with your friends.
