toCv() function is slow about opencv-processing HOT 2 CLOSED

As I replied to you on my blog post:

That “bottleneck” is that the pixel data needs to get moved inside the PImage’s BufferedImage. It’s not a bottleneck so much as the actual work that’s being done. Since Mats are only headers for existing image data (and that image data is already in memory inside the BufferedImage somewhere) it should theoretically be possible to create a Mat in place without copying the pixel data. This is how the process works in C++, for example in Kyle Mcdonald’s ofxCv. However, I don’t know of any way in Java to access the actual memory location of the image data, either to get that location within the BufferedImage or to set it within the Mat. I’m not the world’s most advanced Java programmer though, so my lack of knowledge of such a method is not proof of its non-existence. I’d be glad to hear of a way to accomplish that, but I couldn’t find one in my research and no one else I contacted knew of one.

Thanks for answer. Hope to help with this in the near future.
