Buddy Scanner – A Scanning Application

Amidst the tense Indo-China border conditions in North-east India coupled with the ‘Atmanirbhar Bharat’ initiative, the IT ministry of India had banned 59 China-owned applications, including Cam Scanner, Tik Tok, ShareIt, etc., and thus were also taken down from the Indian Playstore for sovereignty and security. Among the banned 59 applications, CamScanner had been an integral part of daily documentation which allowed users from organizational, governmental, commercial, and academic backgrounds to convert the camera-clicked images of important documents into scanned PDF format. But after the ban of CamScanner, users faced a lot of inconveniences to create these despite the introduction of other alternative Indian scanning applications as these applications were less satisfactory in comparison to CamScanner. Hence to overcome the limitations posed by these alternatives, the application - Buddy Scanner has been proposed, which will use Canny Edge Detection, 4 Point Perspective Transformation to detect the documents edges and provide a good quality transformed image as the output. The Canny Edge Detection increases the accuracy of boundary extraction which will be helpful for detecting the document borders effectively combined with the 4 Point Perspective Transformation to give a well plane aligned image. In addition to this, the application features additional but important functionalities like Optical Character Recognition on images, various options to apply filters and Signature insertion in the images. Along with these additional features, other basic features like reordering of pages, rescanning of images, rotate and flip, delete or add images and renaming the file are also available in the designed application.
