Error : while finding histogram for gray scale image (uint8)

Can anyone tell me how to rrecvtify this error?? I have

Undefined function or variable 'originalImage'.

Error in blobs (line 15) [pixelCount grayLevels] = imhist(originalImage);

Your image variable is not named originalImage. What is it named? Looks like you took some demo code of mine and modified it but forgot to change the name everywhere. Where does the result of your imread() function go to? Chances are that is what you need to send into imhist(). For example

grayImage = imread(fullFileName);
[pixelCount grayLevels] = imhist(grayImage);

oh yeah I fixed it.

does 'imfill' function must be selected manually? Or if I give 'holes' It filles the region by itself?

[Image Analyst]

It seems, according to the documentation, that if you don't specify the 'holes' option, it puts you into an interactive mode where you must click on the image to edit/remove things or finish. I never want that interactive mode so I always specify the 'holes' option.

ok thanks.
