Hi,

We are using multiple Flex 13 cameras in precision mode, and I would like to get the grayscale pixel values at the segments of the detected objects. I tried to rasterize the whole image but this was too slow to work in real-time with mulitple cameras.
Is there a function which could be used to rasterize only a part of the image, or is there some other method to query this data efficiently?

Yes, Rasterize() is expensive for this. Fortunately, we have something for you. You can access the data without rasterizing it into your own buffer. If you call frame->GetGrayscaleData(), it will return a memory pointer that gives you the pixel data. It's formatted one pixel per byte and the total size is camera pixel width * camera pixel height. You can verify this with frame->GetGrayscaleDataSize(). This memory is already there, so there is no overhead to get the pointer to this data and look into it for getting individual pixel values.

Thx,
Doug

Thank you! I quickly tried it and it works like a charm. Somehow I missed these methods...
