Internship - Object Detection in Text Documents


Business documents are challenging to process as most of them contain graphical objects such as tables, images, logos, schemas or signatures. These objects might not only be rich in information, but their presence can also degrade the performance of open-source optical character recognition tools (OCR). Document object detection (DOD) is therefore a crucial step in processing pipelines for digitized documents. It allows to extract each graphical object to be further processed with a dedicated method, such as handwritten signature verification or table parsing.

Despite recent deep learning approaches, DOD remains a challenging computer vision task, as each type of graphical object can appear in a wide range of layouts, shapes or textures. In addition, a very high accuracy is required in order to enhance downstream applications such as document classification or information extraction.

In this role

In this internship, you will explore state-of-the-art document object detection approaches and eventually implement and deploy a web-based prototype of your solution.

You will also study the automatic verification of signatures, which is about determining first whether there is a signature and then that the detected signature matches known samples. This is an important problem to solve, since handwritten signatures are still a widely accepted way of authentication in the business world today.


The goal of the internship is to:

  • Study and compare state-of-the-art machine learning methods for document object detection and for signature verification. The student will have the opportunity to deepen their knowledge in these two fields.
  • Design and implement a tool for document object detection and signature verification. The intern will be able to sharpen their machine learning and software development skills.

What we offer

Join our team as intern and you will find a young, dynamic and culturally diverse working environment.

About your profile
