  1. 1. Improvement of Optical Character Recognition on Scanned Historical Documents Using Image Processing

    University essay from Högskolan i Gävle/Datavetenskap

    Author : Lara Aula; [2021]
    Keywords : Image pre-processing; Tesseract; Optical Character Recognition; Historical documents; Precision and Recall;

    Abstract : As an effort to improve accessibility to historical documents, digitization of historical archives has been an ongoing process at many institutions since the origination of Optical Character Recognition. The old, scanned documents can contain deteriorations acquired over time or caused by old printing methods. READ MORE

  2. 2. Image Analysis of Circulating Tumour Cell Clusters from Imaging Flow Cytometry Data

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Filip Berg; [2020]
    Keywords : MSc; Image Analysis; Segmentation; Otsu Threshold; Watershed; Circulating Tumour Cells; Imaging Flow Cytometry; Technology and Engineering;

    Abstract : Circulating tumour cells (CTCs) are cancer cells that have entered the circulation of the body breaking free from their primary tumour and that can act as progenitors of metastasis. At the time of writing, a study on a novel method to detect and count CTCs using imaging flow cytometry (IFC) is being conducted at Lund University. READ MORE

  3. 3. On the development of an unsupervised probabilistic algorithm for grayscale fluorescence image segmentation

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Magnus Brander; [2018]
    Keywords : bayesian decision theory; bayesian; image segmentation; fluorescence microscopy images; Otsu; Physics and Astronomy;

    Abstract : In the field of computational biology, fluorescence microscopy images often constitute the input source of information. The process of binarization of raw images to delineate interesting objects requires image segmentation into signal and background pixels. READ MORE

  4. 4. Improving character recognition by thresholding natural images

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC); KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Oskar Granlund; Kai Böhrnsen; [2017]
    Keywords : OCR; natural images; thresholding; image segmentation; k-means; Otsu; OCR; naturliga bilder; thresholding; k-means; Otsu;

    Abstract : The current state of the art optical character recognition (OCR) algorithms are capable of extracting text from images in predefined conditions. OCR is extremely reliable for interpreting machine-written text with minimal distortions, but images taken in a natural scene are still challenging. READ MORE
