Poisson blending is a computer vision technique that can be used to seamlessly blend an image into a target image. The blending is done by solving a Poisson equation that describes the gradient of the source image. This equation can be solved using various methods, one of which is numerical methods like the Jacobi method or the Conjugate Gradient method.
By using CUDA (Compute Unified Device Architecture), it is possible to speed up the computation of the Poisson blending by parallelizing the computation on a GPU (Graphics Processing Unit). With CUDA, the computation can be parallelized across many cores on the GPU, which can significantly reduce the computation time. This is because GPUs are designed to handle many concurrent operations and are optimized for data-parallel computation, making them well suited for computer vision tasks like Poisson blending.
To implement Poisson blending with CUDA, one needs to have knowledge of CUDA programming and the specific CUDA API for solving partial differential equations. Additionally, the implementation may need to be optimized for the specific GPU architecture in order to achieve the best performance.
