Hello forum,
I am trying to use the SIFT function
SiftDescriptorExtractor detector;
but I am getting an error SiftDescriptorExtractor is undefined. What #include do I need ? I always have this problem since a year ago. How do I know which function requires which #include folder ? And where do I see how to initialize such functions ?
I went to http://docs.opencv.org/3.0-beta/modules/features2d/doc/feature_detection_and_description.html#sift and it says The SIFT algorithm has been moved to opencv_contrib/xfeatures2d module.
EDIT: Step 2 says to select the opencv source code folder and the folder where binaries will be built (the 2 upper forms of the interface)
Is the source code folder **C:\opencv\sources** ? And where is the folder where binaries will be built ? I don't know how to use cmake and I have no clue what is going on
