Photops is an image processing tool capable of applying filters or performing edit operations on images. It is implemented using CUDA and therefore uses highly efficient parallel programming techniques to perform the operations using the GPU. The tool processes an HD image in less than 0.5ms on a decent GPU. This tool can be employed in bulk image processing or video processing applications to scale systems easily.
- Build the program
It is a command line tool and the source code can be compiled using
nvcc(Nvidia C/C++ Compiler) andg++.
cd Photops
make
The program can be executed using the command line operations.
