Abstract: A user images a portion of a scene (100), for example, using the camera of a mobile device (200) and selects at least two points of interest whose spatial coordinates are generated by a coordinate-generating component (2310). The image and the coordinates are transferred to an analysis module (6310, 6320) installed either in the user's device (200) or a recipient's device (600), which determines at least one dimensional characteristic such as length, area, and/or volume of at least one feature represented in the transferred image.
