2014-07-21 04:56:48 -0600	asked a question	What are the functions that are optimized for NEON instructions What are the functions that are optimized for NEON instructions? Is there a list somewhere? Using grep (grep -r "NEON" .) inside the opencv source shows only very few files. http://www.mcs.anl.gov/events/workshops/ashes/2013/slides/Gaurav_ashes13.pdf - Slide 15 says only 6 functions have NEON Intrinsic Optimized Functions in 2.4.3.

Scanning dependencies of target android_package make[2]: * No rule to make target `bin/classes.jar.dephelper', needed by`package/bin/OpenCV_2.4.9_binary_pack_armv7a-release-unsigned.apk'.
