Separation of Machine-Printed and Handwritten Text in Archival Documents

Mahsa Vafaie

FIZ Karlsruhe

One major challenge to date in the field of Document Processing is transforming analogue documents into computer-readable formats. Optical Character Recognition (OCR) and Handwritten Text Recognition (HTR) techniques are traditional methods for this transformation. Despite progress in text recognition through OCR and HTR, this issue remains largely unresolved, particularly regarding historical documents stored in archives, due to visual complexities such as overlapping areas, paper degradation, and ink fading. In the context of the project “Wiedergutmachung”, we propose a pipeline to address the issue of text type heterogeneity in single document images by decomposing the document into its constituent text types—handwritten and machine-printed text, to enhance text recognition accuracy by utilising appropriate models for each text layer, in order to improve the quality of final transcripts.

Practitioner’s Tricks for Image Labeling

Antonio Rueda-Toicen

Voxel51

This talk covers methods to label images in the main computer vision tasks:

  • Classification (identifying objects)
  • Segmentation (localizing at the pixel level)
  • Detection (localizing with bounding boxes)

We look at combining zero-shot classifiers, like CLIP, with active learning. We will discuss key implementation details such as:

  • Power and pitfalls of cross-entropy loss
  • Model calibration methods
  • Choices between single-class and multilabel classification methods
