Possible Speed-Improvement for FlashSURF #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Maybe I have overlooked something, but I wonder if there is a way to speed
up the matching process a bit in the case where you have several reference
images. 

Right now it looks like that for every call to getMatchesToReference a new
integral bitmap is calculated and the whole extraction of interest points
is being run. Since there is only one buffer for reference maps it is
necessary to rewrite that buffer for every reference map that should be
checked. However in order to find matches all is needed is the points of
interest which do not change in static images (except if the options are
changed).

So wouldn't it be faster to have a method that allows me to directly send
in the previously extracted points of interest of a reference map which I
only have to calculate once and can store?

Mario, I've made lots of additions and improvements on this task.
And I guess it should really speed up the multi reference dection
