Install OpenCV 2 and 3 simultaneously in the OS X 10.10 environment through HomebrewPreviously, it took a long time for me to configure OpenCV on Mac. Most people who use the Win platform will install the OpenCV library for VS. After trying to configure and build the OpenCV project using Xcode, due to the strangeness of the Xcode environment and the imperfect C +

It also allows sharing of CPU, RAM, and I/O. the granularity for allocating processing resources to a partition can reach 1/10 of a CPU. by using the unlimited partition feature, you can even exceed the number of hardware configured on the partition, that is, the capacity (EC) to be used ).
