Detect and correct imperfections from scanned documents with Filestack’s Document Detection
Filestack’s Document Detection automatically generates a bounded box to fit the entire document and preprocesses it to increase the OCR (Optical Character Recognition) accuracy.
Why Should You Use Filestack’s Document Detection?
Best OCR API for Document Detection Coupled with Intuitive Preprocessing Solutions
Filestack document detection maximizes its optical character recognition accuracy with the help of both supervised and unsupervised machine learning algorithms. These methods help our Document Detection package remain one of the most advanced options available on the market today.Learn More
How Does Document Detection Work?
- 1 Generate the detected mask of the document in the image for segmentation using our custom designed deep neural network that has trained on sets of thousands of image files.
- 2 Find the most accurate circumscribed polygon over the detected mask. This part would find the predicted perspective edges of the document within the image.
- 3 Warp the predicted document in the image to fit the whole image, all while keeping its aspect ratio. This part would fix any rotation, etc. in the document.
- 4 Denoising the warped image, fixing the distortions, and generating the final result.

How Can Document Detection Benefit Your Application?
Based on how you set the
preprocess options, Filestack will return one of three different
- 1 Detect the document in the actual image and return its coordinates.
- 2 Detect the document in the image, find the coordinates, transform the document based on its corners to fit the largest rectangle, also known as warping.
- 3 Detect the document in the image, find the corners, warp the document, and apply preprocessing filters to make it cleaner for OCR.

Use Filestack’s Document Detection with Workflows
Chain together tasks in our simple Workflows User Interface to auto-detect your client's document content. Filestack simplifies the process by scanning every file on upload while generating a CDN link for every file you upload so that you can create workflows to manipulate said files. Set rules and conditional logic for handling file coordinates or size and decide how to transform and deliver your files.

What Filestack Can Do For You
How valuable would it be to “see” what is in every image? With our image auto-tagging service, you can easily abstract what objects appear in your uploaded images. People, animals, transportation, and thousands of other categories are at your disposal.
Explicit Content Detection
Moderate your images to ensure you are only showing content that comply with your rules and boundaries. By implementing “safe for work” and a “not safe for work” score, our image tagging service can help you automate content moderation so you can focus on your core business.
Sometimes knowing which objects are in your photos isn’t enough -- you need to know where they are, too. Filestack Object Detection uses state-of-the-art neural networks to detect and locate common objects in photos.
