I am trying to have a C++ lib for the watershed function. I have read the instructions at https://www.mathworks.com/help/images/ref/watershed.html
Usage notes and limitations:
bwconncomp only supports 2-D inputs.
The conn arguments must be a compile-time constant and the only connectivities supported are 4 or 8. You can also specify connectivity as a 3-by-3 matrix, but it can only be [0 1 0;1 1 1;0 1 0] or ones(3)
The PixelIdxList field in the CC struct return value is not supported.
Codegen now tells me that I have an unsupported matlab function call which is bwconncomp. I am not sure how to resolve this. My code is below.
function L = watershed(A) %#codegen
conn = [0 1 0;1 1 1;0 1 0];
cc = bwconncomp(imregionalmin(A, conn), conn);
L = watershed_meyer(A,conn,cc);

Okay I realized that watershed is only available for codegen for Matlab version R2015a onwards. I am using R2014b.
