These include Otsu's thresholding, maximum entropy threshold, and mixture modelling thresholding. (2004), "Survey over image thresholding techniques and quantitative performance evaluation.", Journal of Electronic imaging 13(1): 146-168 ( on Google Scholar).įiji has several plugins found in the menu Image › Adjust › Threshold for automatic calculation of an image threshold. An evaluation of over 40 of these can be found in this paper: There are many algorithms you can use to calculate the threshold without introducing user-bias.
The image can be converted to a binary image via the menu command Image › Type › 8-bit. The background of the thresholded image can be made light or dark. analysis of variance followed by Tukey’s post hoc test was used to determine significance at the 5 198 Y. Data are presented as the percentage of the healed. The Color space option allows you to choose between HSB, RGB, Lab, and YUV. ImageJ (National Institutes of Health, Bethesda, MD, USA) was used to measure the denuded area in each image. The Threshold color option allows you to choose between Red, White, Black, or B&W as the thresholding color. The Thresholding method option allows you to choose a thresholding techniqe other than the default. It is used in many scientific peer-reviewed publications, with over 1000 articles in diverse. For color images, setting the threshold is done with the command sequence Image › Adjust › Color Threshold. ImageJ is a great tool to process images and perform analysis.
