Binarization of Document Images: A Comprehensive Review

WebMar 20, 2024 · [36–38] The inter-measurement differences were significantly higher after image binarization using the manual algorithm compared to all automated algorithms. This effect was independent of age. Due to this, automated binarization algorithms should be preferred over manual approaches in OCTA image binarization. WebIn many applications, binarization is a critical preprocessing step and helps facilitate other document processing tasks such as layout analysis and character recognition. In such pipelines, the quality of the binarization can greatly affect system performance, as errors made in the binarization step can propagate to downstream tasks.
