Hello,
I have some fiducial points in an image and I need the user to select the first point and get the coordinates of that point and the colour vector in workspace.
At the moment I have only found:
Data cursor, but it only gives the location, not the colour Impixel, apparently should give both, but it is a bit confusing and it's not working very well imroi only gives location too from what I've read
Can you please help me with this? Also, can the colour vector be in the Lab colorspace? (transform the image first, and then click in the point?)
Many thanks! Hector

Use impixelinfo(), available in the Image Processing Toolbox. Instructions are in the help.

Let's continue the conversation under my answer, not yours. But it looks like that should give you the lab values, not the rgb values because lab_fabric is a different array than RGB.
