If you hover the mouse cursor over the detector image the data shown to the
right of the image will show the X and Y co-ordinates of the pixel the mouse
cursor is pointing to and the Hue, Saturation & Value for the pixel at which
the cursor is pointing.
Using the “Frame Analysis” web
-page you can run the cursor over similarly
coloured areas and then either accept only those areas, or reject those areas,
using the range of Hue, Saturation or Value seen in the data beside the image.
Whether you pick H, S or V will depend on the pixels of interest as you need to pick the
characteristic which gives a close continuous range of values to either accept or reject.
Note:
Colour Filtering is per region and so you will need to apply it to each region required,
selecting the region(s) to which you wish to apply the colour filtering is performed using the
“Region” drop
-down menu below the detector screen shot and to the left of the H, S, V acceptance
or rejection settings.
Click the “Save” button when you have finished.
