CUDA Super-Resolution
This is a C++ implementation of the framework proposed in our paper "GPU Accelerated Time-of-Flight Super-Resolution for Image-Guided Surgery". It employs maximum a posteriori (MAP) estimation to obtain an improved image of higher resolution from multiple low-resolution images. In particular, it can be used to enhance depth maps from range sensors such as Time-of-Flight (ToF) cameras.
Super-resolution is known to be a computationally demanding problem. This is a main limitation for many practical applications having requirements regarding run time. Our implementation accelerates super-resolution on the graphics processing unit (GPU) using NVIDIA's CUDA platform. In particular, for super resolution of range images in image-guided surgery, our frameworks enables interactive frame rates computing an upsampled image from 10 input frames (200 x 200 pixel) with an upsampling factor of 2 in 109 ms (hardware: NVIDIA GTX 580). Please see our paper for details.
Our source code package already comes with some example images and a demo application. | | |
