A non-parametric binarization method based on ensemble of clustering algorithms
TL;DR: A novel binarization technique is found to be capable of handling almost all types of degradations without any parameter tuning, and is the winner of DIBCO 2019 competition.

The lifecycle of a digital historical document: structure and content
TL;DR: Tests indicate the superior performance of the whole semantics-driven approach both over manual transcription and over the semi-automated application of off-the-shelf OCR and the use of a conventional (text and layout) document format.
Proceedings ArticleDOI
Improving star tracker centroiding performance in dynamic imaging conditions
TL;DR: This work presented an image processing algorithm for star images that preserves star tracker detection accuracy and is able to detect dim stars up to slew rates less than 10°/s and introduced a new algorithms for star acquisition in moderate slew rates that combines positive features of existing algorithms.
Journal ArticleDOI
Integrated use of Landsat TM and SPOT panchromatic imagery for landslide mapping: case histories from southeast Spain
TL;DR: In this paper, the authors demonstrate the capabilities and limitations imposed by spatial and spectral resolution in Landsat Thematic Mapper (TM) and SPOT panchromatic space imagery.
