Tutorial / Projection objects
Projection objects are used in various ways for image or field analysis, as shown in the following examples. Let us choose now a color image as input, UVMAT_DEMO02_color/images/frame1.jpg' (the folder 'UVMAT_DEMO02_color' is accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/).
Plotting a luminosity profile
Create a line by the menu bar command 'Projection Object/line'. A new GUI 'set_object' appears on the right side, with default settings Type='line', ProjMode='projection'. Draw a line with the mouse, left hande side button to mark the beginning and end of the line. The luminosity profile, with the three rgb components, appears in a new GUI 'view_field'. The line can be moved with the mouse, or by directly introducing the coordinates of the line in the table [Coord] of the GUI set_object.
