Cuda-npp image and video processing

One 、What is NPP?

        NVIDIA Performance Primitives library (NPP) Is a series of library functions for accelerating the process ,NPP The original goal of is for image and video processes , Now it is used by development engineers in many other fields , Including signal processing .NVIDIA NPP yes 2D Image and signal processing CUDA Acceleration Library .NPP Libraries can maximize flexibility , While maintaining high performance . It can be used in the following two ways NPP library

• As a separate library , You can add GPU Speed up
• Can be added to developers GPU In the code , As a collaborative library for effective interoperability

        Both methods allow developers to take advantage of NVIDIA gpu A lot of computing resources , At the same time, reduce development time .

Two 、API Interface document

There is an official explanation here , This article will not introduce , If there is time later , Then introduce the use of interfaces .

• Universal interface ： https://docs.nvidia.com/cuda/npp/general_conventions_lb.html
• Image processing interface ：https://docs.nvidia.com/cuda/npp/nppi_conventions_lb.html
• Signal processing interface ：https://docs.nvidia.com/cuda/npp/npps_conventions_lb.html
