Open in MATLAB Online Download ADAPTIVETHRESHOLD An adaptive thresholding algorithm that seperates the foreground from the background with nonuniform illumination. bw=adaptivethreshold(IM,ws,C) outputs a binary image bw with the local threshold mean-C or median-C to the image IM. ...
Local adaptive thresholding is used to convert an image consisting of gray scale pixels to just black and white scale pixels. Usually a pixel value of 0 represents white and the value 255 represents black with the numbers from 1 to 254 representing different gray levels. Unlike the global ...

The proposed approach can be regarded as adaptive local thresholding since we focus on the analysis of local rather than global features. By applying the validity-guided fuzzy c-means algorithm, the spatial partitioning of an image into sub-regions in our method becomes context-oriented and fully...
This paper presents a new method—the Technique of Iterative Local Thresholding (TILT)—for processing 3D X-ray computed tomography (xCT) images for visualization and quantification of rock fractures. The TILT method includes the following advancements. First, custom masks are generated by a fracture...
