version 1.0 (333 KB) by

Select objects in binary N-D array. Can replace Matlab's "bwselect" which is limited to 2D matrices.



View License

This function selects object(s) in binary N-D array. It can replace Matlab's "bwselect" (minus the interactive mode) which is limited to 2D matrices.

Xin - input N-D array. Required.
conn - connectivity definition, can be either a scalar or connectivity array, with same number of dimensions as the input array. If empty or omitted, conn will be set to scalar 3^ndims(Xin)-1.

I or I1, I2, ... - selected indices (single linear index or series of subscripts for each dimension of the input array.

Xout - Output N-D array (same size as Xin), with only the connected-components objects which overlap the indices set.

Examples for usage can be seen in the "testSuite.m" file. The image above is the result of running the test suite 2D part.
