Introduction

In this article, we are going to learn how to extract handwritten text from an image using one of the important Cognitive Services API called Computer Vision API. So, we need a valid subscription key for accessing this feature. So before reading this article, you must read our previous articles related to Computer Vision API because we have explained other features of Computer Vision API in our previous article.

Before reading this article, you must read the articles given below for Computer Vision API Knowledge.

Requirements


These are the major requirements mentioned in the Microsoft docs.

  1. Supported input methods: Raw image binary in the form of an application/octet stream or image URL.
  2. Supported image formats: JPEG, PNG, BMP.
  3. Image file size: Less than 4 MB.
  4. Image dimensions must be at least 40 x 40, at most 3200 x 3200.

Provision a Computer Vision Subscription Key

After clicking the "Computer Vision", It will open another section. There, we need to provide the basic information about Computer Vision API.

Output


Handwritten content from an image using Computer Vision API. The content is extracted (around 99.99%) from the given image. If any failure occurs in detecting the image,it means that the Vision algorithm is not able to identify the written content.
