This page provides a list of all the functionality available in the latest release of CUVI Library.

Modules

CUVI comes in following image processing modules.

CUVI Core

CUVI Core includes the following helper functionality:

CuviImage A C++ class to hold image data on the device. It has the following methods CuviImage(); - default constructor CuviImage(CuviSize size, Cuvi32u depth, Cuvi32u channels) - Main Constructor. throws exception in case of failure CuviImage(const CuviImage&) - copy constructor CuviImage(const CuviMat&) - copy constructor to initialize from CuviMat Upload(void* pSrcHost, size_t srcPitch, CuviStream* stream = NULL) - Copy image data from host to device. Async operation supported Download(void* pDstHost, size_t dstPitch, CuviStream* stream = NULL) - Copy image data from device to host Show(char* title = "CUVI Image",int milliseconds = 0) - Render device image directly on the screen ~CuviImage() - Destructor. Frees Device Memory. throws exception in case of failure
CuviMat A C structure to hold image data on the device. It has the following methods
