Project Description: jscanify

What is the project about?

jscanify is a JavaScript library that provides image processing functionalities for detecting and extracting paper documents from images or video streams. It leverages the power of OpenCV.js to achieve this.

What problem does it solve?

It solves the problem of manually cropping and correcting the perspective of documents in images. It automates the process of identifying the document boundaries and extracting a rectified image of the document, even if it's skewed or distorted in the original image. It also adds glare suppression and multi-colored paper support.

What are the features of the project?

• Paper detection & highlighting: Identifies the edges of a paper document in an image and visually highlights them.
• Paper scanning with distortion correction: Extracts the detected paper region and applies perspective correction to produce a flat, rectangular image of the document.
• Glare suppression: Reduce glare on the image.
• Multi-colored paper support: Detects multi-colored paper.

What are the technologies used in the project?

• OpenCV.js: A JavaScript version of the popular OpenCV computer vision library, used for image processing tasks.
• JavaScript: The primary programming language.
• Node.js: Supported for server-side usage.
• React: support.

What are the benefits of the project?

• Automation: Automates the document scanning process, saving time and effort.
• Improved Image Quality: Corrects perspective distortion, resulting in cleaner and more readable document images.
• Cross-Platform: Works in web browsers, Node.js environments, and with frameworks like React.
• Easy Integration: Provides a simple API for easy integration into web applications.
• Open Source: Freely available and open for contributions.

What are the use cases of the project?

• Document Scanning Apps: Can be used as a core component in mobile or web-based document scanning applications.
• Image Processing Tools: Integrate into image editing software to provide document extraction features.
• Online Forms: Enhance online forms that require document uploads by automatically processing and correcting submitted images.
• Real-time Document Processing: Process video streams from a camera to detect and extract documents in real-time.
• Export to PDF: It is possible to export the paper to PDF.
