Could you explain why "res = min(dark,bright)<thGeo1 && max(dark,bright)>thGeo2;"?

I got this error if the input matrix having all zero elements.
r =
Empty matrix: 0-by-1
c =
Empty matrix: 0-by-1
how to avoid this error or how to skip this matrix

I'm sorry I used 2 user-defined function in the code. I have updated the code and replaced them with built-in functions.


The Procedure "susanCorner" gives the strange result!
What is a "imread1(" and "fis(" in "testsusan"?


2 insignificant user-defined function were replaced by system function.
