Instant Feedback Rapid Prototyping for GPU-Accelerated Computation, Manipulation, and Visualization of Multidimensional Data
Table 1
Timings for selected operations on 3 different volumes. The speedup factor between CPU and GPU is calculated as the lowest CPU time (8 threads) divided by the GPU time. The 3D Euclidian distance transform operates on normalized (pixel values in ) volumes with a solidity threshold of 0.5. The CPU implementation is our own, including the multithreading. Intensity rescaling and median filtering use ITK’s CPU-based implementation. The median filter takes the direct neighborhood of each voxel into account, that is, a box of 27 voxels in total.
