Date of download: 6/23/2016 Copyright © 2016 SPIE. All rights reserved. CUDA Profiler Timeline for SS-OCT processing and volume rendering pipeline. Memcpy HtoD [async] is transferring the raw data, subDC_PadCom is a kernel with the function of type conversion, DC subtraction, and zero padding. spVector2048C_kernelTex is a kernel called by the cuFFT library which performs the fast Fourier transform (FFT). CropMLS performs the modulus and Log. Memcpy DtoA [sync] copies the processed OCT data into a CUDA 3D array for volume rendering.
