I just gathered the first data for my flow experiments using PIV techniques. I decided to use the Matlab tool you build to analyze it (with success!). However, we wanted to check to see if taking the mean of the correlation peaks would increase the precision. Is there an easy possibility to export the correlation data per window to the workspace? Or is this something I would have to built myself? Thanks in advance for your reply
if you want to use the DFT multipass version, you can open piv_FFTmulti.m, and
look for the variable "result_conv". That is the correlation matrix of each
vector. The variable is not stored (it is overwritten each time a correlation is
performed), but you can modify the script and store the correlation matrix.
All the best,
