- Abstract: Extraction of text regions and individual text lines from historic documents
is necessary for automatic transcription. We propose extending a CNN-based text
baseline detection system by adding line height and text block boundary
predictions to the model output, allowing the system to extract more
comprehensive layout information. We also show that pixel-wise text orientation
prediction can be used for processing documents with multiple text
orientations. We demonstrate that the proposed method performs well on the cBAD
baseline detection dataset. Additionally, we benchmark the method on newly
introduced PERO layout dataset which we also make public.

"Detect Any Text" is an advanced paradigm that unifies scene text detection, layout analysis, and document page detection into a cohesive, end-to-end model.
A pivotal innovation in DAT is the across-granularity interactive attention module, which significantly enhances the representation learning of text instances.
Tests demonstrate that DAT achieves state-of-the-art performances across a variety of text-related benchmarks.

We present an unsupervised deep learning method that embeds document image patches to a compact Euclidean space where distances correspond to a coarse text line pattern similarity.
Text line segmentation can be easily implemented using standard techniques with the embedded feature vectors.
We evaluate the method qualitatively and quantitatively on several variants of text line segmentation datasets to demonstrate its effectivity.

A common method is to train a deep learning network for embedding the document image into an image of blob lines that are tracing the text lines.
This paper presents an unsupervised embedding of document image patches without a need for annotations.
We show that the outliers do not harm the convergence and the network learns to discriminate the text lines from the spaces between text lines.
