hi list
i wonder if this might be possible with pdp. i have to do some heavy image processing (filters and colordetection) on 4 videostreams in realtime, which is a overload for my cpu. all frame manipulations like gain/saturation/stresh/cheby are applied on the whole resolution 320x240. but actually i just need to calculate a part of the image where i do the tracking. therefore it would be great if i could crop a region of the stream and start working just with this part of the image which would reduce the data to process drastically.
would this be possible within pdp. i think there is no object around yet, but would the concept and structure of pdp allow this kind of operation?
any ideas?
best marc
lucky you,
pdp_cropper from pidip
suerte, sevy
hope you an build pidip if you need it, i noticed a few problems with newer libraries building it yesterday on gentoo, and not much time to fix it.

hi yves
well i am a lucky man. CPU is now down on 10% which will give me enough power to calculate four streams. i still have to test around, but it looks like it's exactly what i need and it seems to work stable.
i will definetly have a beer tonight and will think of the miracle happened to me today.
all the best marc
