IRS-1C LISS III land cover maps at different spatial resolutions used in real-time accidental air pollution deposition modelling
TL;DR: In this article, the roughness of each land cover class is assigned and used as input to a real-time dispersion model to estimate the most realistic deposition pattern. But, the authors do not consider the temporal variations in roughness at a seasonal time scale.

An analysis of the transition proportion for binarization in handwritten historical documents
Marte A. Ramírez-Ortegón,L. Leticia Ramirez-Ramirez,Volker Märgner,Ines Ben Messaoud,Ines Ben Messaoud,Erik Cuevas,Raúl Rojas +6 more
TL;DR: This analysis extends to thresholding methods that rely on Bayes rule, and it also gives the mathematical bases for potential applications of the transition proportion as a feature to estimate stroke width and detect regions of interest.

Thresholding techniques and their performance evaluation for weld defect detection in radiographic testing
TL;DR: Performance criteria are used to conduct a comparative study of the thresholding methods based on the gray level histogram, the 2D histogram and the locally adaptive approach to weld defect detection in radiographic images.
Journal ArticleDOI
Local thresholding of degraded or unevenly illuminated documents using fuzzy inclusion and entropy measures
TL;DR: A local thresholding method based on specific fuzzy inclusion and entropy measures which is an open, automated and adaptable procedure and some implementations of a more general algorithm are seen along with some specific results.

A Novel Approach for Binarization of Overlay Text
Zhike Zhang,Weiqiang Wang +1 more
TL;DR: A new binarization approach to extract text pixels from complex background in video frames, using the K-means algorithm in the RGB color space and the text cluster is selected based on the text polarity.
