Blackboard Captor: An Android Camera Application

Android application to process pictures of the blackboards.

Blackboard Captor is an open-source Android application with which you can select pictures from your album or take a picture of the blackboard through the user’s camera. It will recognize the blackboard (rectangles) in the photo, crop out the extra image, correct it, optimize it, and save it on the user’s mobile phone. At the same time, we also provide replacements for the background color, which helps users to obtain better results.

Blackboard Captor segments the location of the blackboard by handcrafted features designed by myself and corrected by perspective transformation.

As the leader of this project, I proposed the idea of this project, designed the blackboard image segmentation process, implemented all the source code, and designed the logo.

Blackboard Captor is a open-source project. Source code is available at GitHub.
