MathWorks Inc image processing toolbox 2 matlab v2019a
VistoSeg workflow for Visium H&E image segmentation. (a) Raw histology image of human dorsolateral prefrontal cortex. (b) Gaussian smoothed and contrast-adjusted image of the raw histology image in (a). (c) Enhanced image from (b) converted from RGB color space to L*a*b color space. (d) Different color gradients (k = 5) identified by the <t>MATLAB</t> function imsegkmeans applied to the raw histology image. Cluster 3 corresponded to the nuclei, stained blue in the raw histology image. (d’) An inset of nuclei cluster 3 in (d). (e) Output of refineVNS from nuclei cluster 3 (d’). The refineVNS function allows for separation of adjacent nuclei. (f) Final binary nuclei segmentation obtained from (e).
