Hi,
What do you mean about measuring a picture ? If you only want to get the resolution, use P=imread('picturename.format')
You will store a matrix containing all the pixels. Then the size of your picture is the number of line and the number of columns.

Where did you upload your image to? You forgot to tell us. You can measure things manually with imdistline().

The image is browse from other file. I'm using the push button to browse the image. I was try the 'imdistline' syntax and the result shows only in pixel value. the problem now is, i want to convert the pixel into other unit, such as 'cm' 'mm' in the picture. Please show or share with me the formula and the code that i can be inserted in GUI
