What is Optical Character Recognition (OCR)?.Step-by-Step Introduction to Basic Object Detection Algorithms.If you are new to object detection and computer vision, I suggest going through the following resources:

So, in this article, we will explore some very famous and effective approaches for the OCR task and how you can implement one yourself. For starters, it is filled with problems like different fonts in images, poor contrast, multiple objects in an image, etc. But advances in the computer vision and deep learning field mean we can build our own OCR system right now!īut building an OCR system isn’t a straightforward task. OCR systems used to be quite expensive and cumbersome to build a couple of decades ago. So, everything from scanning documents – bank statements, receipts, handwritten documents, coupons, etc., to reading street signs in autonomous vehicles – this all falls under the OCR umbrella. Honestly, OCR has applications in a broad range of industries and functions.

We will leverage the OpenCV library and Tesseract for building the OCR systemĭo you remember the days when you had to fill in the dots of the right answer during an exam? Or how about the aptitude test you gave before your first job? I can vividly recall the olympiads and multiple-choice tests where universities and organizations used an Optical Character Recognition (OCR) system to grade the answer sheets in droves.
