Unable to find the location of the pixel with the minimum gray level

I want to find the location of the pixel in the image which has the minimum gray level. I tried the code below. But it gives me the coordinates of more than one pixel. What I need is to find the location of one pixel that has the minimum gray level. Any suggestion would be appreciated.

    I=imread('FP00000f002b04u_01.png')
	minValue = min(I(:))
	[row, column] = find(I == minValue);

A quick guess. Maybe there are more than one minimum? Then you need to decide. Maybe anyone is good enough?

Hi @Yongjian Feng,

Any one point would be good enough. I was wondering how would I select that point.

If any one minimal point is sufficient, then how about the first?

[row, column] = find(I == minValue,1,'first');

I'm not really sure how you intend to use it, but that's one way.

Hi @DGM,

That helps. Thank you.
