Dear all,

I'm am new with Matlab, and have been having some trouble finding help for the following problem:

I have a grayscale 8 bit image and would like to locate some features of interest. I am unable to threshold the image as there are other features of the same grayscale that I am not interested in. Therefore I would like to be able to find a pattern of pixels of 2 pixels wide by 4 pixels long, which are in the range of 112 to 80 in the intensity value.

I appreciate any help you can give.

Kind Regards

Anna

Anna:
Post some images with the object your interested in identified
(outlined, pointed to with arrows, etc.) You can use http://drop.io
if you're looking for a place to post your images.

Your question is too vague otherwise. Maybe you're looking to find an
exact array of 8 numbers in a 2 by 4 array in a larger array. Like
100 234 213 211
194 166 241 188
in a 1280x1024 uint8 image array.
Or maybe those numbers are not exact and you're just looking for some
kind of general pattern or shape. No way of telling unless you supply
an image.
