(Opencv is designed to execute as quickly as possible, focusing on real-time applications. It is written in optimized C code to take full advantage of multi-core processors. If you want to get faster processing speed on the Intel platform, you can purchase Intel's high-performance multimedia library IPP (integrated performanceprimitives). The IPP library contains many functions optimized from scratch, covering multiple application areas. If the system has installed the IPP library, opencv will automatically use the corresponding IPP library at runtime.)
