I’ve just had a first look at the NVidia Performance Primitives library (NPP). The nVidia web pages advertise its feature set as including Canny Edge detection. In the documentation for the V1.0 release it seems to be a bit tricky to get to the pages mentioning edge detection.
When you enter the documentation for the “NPP Image Processing” module from the main index.html, you end up on this page which does not mention Canny at all file:///doc/html/group__nppi.html
However in the “Files” documentation for nppi.h header file the Canny features are mentioned.
To me it seems that the “Modules” documentation for image processing is a bit outdated and needs to be re-generated. Or for some reason it doesn’t pick up the Canny related functions as belonging to the Image Processing Module.
Please fix ;-) Also the funny spelling error “piexel” instead of “pixel”. This made me twietch a little ;)
PS: by the way, can we enable forum searches for 3 letter keywords, such as NPP?
