Re: fast drawing in delphi

Andreas,
well, the idea is to show a nearly real-time neural network classifier doing
the job, so we get data from a multi-channel sensor, at a speed of
5,000-10,000 data points every 10 milliseconds. the neural network map does
classifies the data using the Kohonen algorithm, and I use a wavelet
algorithm to process and find data clusters from the obtained Kohonen map,
it takes nearly 20 milliseconds for math processing, but after all
calculations I have to draw the "current" data map, which takes lot of time
(nearly 20 milliseconds or more), so time resolution for showing the current
data map decreases from an ideal case (every 10 ms) to 50 ms. I believe I
can go down to 10 ms for math processing (I work on that now, math methods
optimizing and possibly Assembler coding), so by decreasing drawing time,
the time resolution for showing neural network response could be improved.
So, achieving a 40 ms resolution will be perfect (just like the PAL video
standard!)
Yes, real time for this experiment is 100 times per second. If we can go
drawing 25 images times per second, that will be enough
