Patient realignment in magnetic resonance imaging of the head: an algorithm using mathematical morphology for feature extraction.
TL;DR: A method for the accurate extraction of the corpus callosum, the cerebellum and the brain area in a sagittal scan of the head is developed by selective thresholding designed to remove the low texture content and then applying morphological techniques.
Proceedings ArticleDOI
Adaptive Image Enhancement for Fluorescence Microscopy
TL;DR: A novel image enhancement method based on adaptive local region sizes is proposed, which can correctly highlight salient objects from changing background intensity and is validated by comparison with ground truth segmentations of cell micrographs.

Restoration of geometrically aberrated images using a self-organising neural network
M. B. Sukhaswami,Arun K. Pujari +1 more
TL;DR: A new method is proposed in this paper to restore geometrically aberrated images based on Kohonen's model of self-organizing neural network to handle different types of aberration including distortion, field curvature and astigmatism.

Global Binarization of Document Images Using a Neural Network
Adnan Khashman,Boran Sekeroglu +1 more
TL;DR: A new approach that combines a global thresholding method and a supervised neural network classifier is proposed to enhance scanned documents and to separate foreground and background layers.
