Collecting a good labelled dataset to learn is not cheap compared to synthetic data.Text in handwriting can have variable rotation to the right which is in contrast to printed text where all the text sits up straight.Cursive handwriting makes separation and recognition of characters challenging.Text in printed documents sit in a straight line whereas humans need not write a line of text in a straight line on white paper.Poor quality of the source document/image due to degradation over time.Handwriting style of an individual person also varies time to time and is inconsistent.Huge variability and ambiguity of strokes from person to person.Want to extract data from handwritten forms?

In this article we will be learning about the task of handwritten text recognition, it's intricacies and how we can solve it using deep learning techniques. Recognizing handwritten text is termed Intelligent Character Recognition(ICR) due to the fact that the algorithms needed to solve ICR need much more intelligence than solving generic OCR. Recent advancements in Deep Learning such as the advent of transformer architectures have fast-tracked our progress in cracking handwritten text recognition. Nevertheless it's a crucial problem to solve for multiple industries like healthcare, insurance and banking. The high variance in handwriting styles across people and poor quality of the handwritten text compared to printed text pose significant hurdles in converting it to machine readable text. Although OCR has been considered a solved problem there is one key component of it, Handwriting Recognition or Handwritten Text Recognition(HTR) which is still considered a challenging problem statement. This growth is driven by rapid digitization of business processes using OCR to reduce their labor costs and to save precious man hours. Optical Character Recognition(OCR) market size is expected to be USD 13.38 billion by 2025 with a year on year growth of 13.7 %. ![]()
