cvCornerFast not available? #34

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Would like to use cvCornerFast(IGray, inFASTThreshhold, inNpixels, 
inNonMaxSuppression, &numCorners, & corners) in javacv but the function is not 
available?...
2. Can't find the function

What is the expected output? What do you see instead?
 - No errors in eclipse, how ever there is compilation problems

What version of the product are you using? On what operating system?
- The latest javacv running on windows 7, 64 bit (not that it should make that 
big of a difference)

Please provide any additional information below.

Thanks in advance!

cvCornerFast() is not a function of OpenCV or of any of the other libraries 
supported by JavaCV. If you want to use an external library not supported by 
JavaCV, I suggest you use JNA https://jna.dev.java.net/ to easily call it from 
Java.

Perhaps I've misunderstood it then. But, it looks like it on:

"2009-08-31 FAST is now officially in OpenCV" on 
http://mi.eng.cam.ac.uk/~er258/work/fast.html

Do you know how I can make it work in my javacv project?

As far as I can see, they decided to implement it as a C++ class FAST declared 
in cvaux.hpp. Since this is C++, it is not part of JavaCV, details in this wiki 
entry:

Sorry for the previous post. Should have realized. I'm curious though, u think 
that I can use a wrapper around the C implementation provided on the same page?
