Mahotas – Getting Labeled Max Array
In this article we will see how we can obtain the labeled max array of the in mahotas. Labeled images are integer images where the values correspond to different regions. I.e., region 1 is all of the pixels which have value 1, region two is the pixels with value 2, and so on. By convention, region 0 is the background and often handled differently. We can create a labelled region with the help of mahotas.label method.
We can get the size of each region with the help of mahotas.label_size method, this size is measured simply as the number of pixels in each region. We can instead measure the total weight in each area.
In order to do this we will use mahotas.labeled.labeled_max method
Syntax : mahotas.labeled.labeled_max(array, labeled_img)
Argument : It takes two numpy.ndarray object as argument i.e random array of region shape and labeled region
Return : It returns ndarray of numpy.float64 values
