Mean thresholding
WebThresholding (image processing) Original image. The binary image resulting from a thresholding of the original image. In digital image processing, thresholding is the simplest method of segmenting images. From a … WebMay 18, 2007 · The inclusion of the one non-zero measure would result in a non-zero mean for the gene, thus defeating the purpose of adopting the posterior median thresholding rule. Thus, in this context, combining the data before thresholding is preferred. Averaging over all the mr replicates, we obtain a mean contrast X ¯ i ⋅ ⋅ for each gene i.
