If you need to see anti-aliasing then use the RUN_THERMAL script in
the same directory and you'll see antialiasing working on the thermal
targets, honest. Use the '[' and ']' keys to modify the sensor gain.
I'll investigate and let you know ASAP what's wrong with the
optical sensor.
In the mean time look at the attached gif for an image of an
anti-aliased thermal target. The anti-aliasing is most noticeable
on the edges of the high contrast engine cowling shilouette and
wheels, for the rotors I used a different AA method which works
well at some angles, not quite so well at others. This is an
unmodified snap of an Indigo2 IMPACT screen.
The image dithering is due to the conversion to 8bit gif format,
there is also some deliberate horizontal sensor banding over the
image.
Cheers,
Angus.
