Forum added

Hi, due to the increasing amount of PIVlab users and questions, I enabled a forum in this blog where questions can be asked. I am hoping that this can act as a central place for all comments and questions and that I can reply faster to questions without forgetting some of them...
I disabled the comments temporarily to see if the forum could work....

Optical flow in PIVlab

Image
Welcome wOFV (wavelet-based optical flow velocimetry) to the family of open-source and easy to apply velocimetry algorithms! I released the beta yesterday evening (just before leaving to holidays 😀): Optical flow in PIVlab, see the video above for some comparisons to classical PIV. Download here: https://github.com/Shrediquette/PIVlab/releases Implemented by Bryan E. Schmidt, Gauresh Raj Jassal from Flow Physics and Imaging Laboratory at case.edu and me.

PIVlab 3.00 released

Image
  I have just released PIVlab 3.00. There are several changes in the way the graphics are drawn, the way the data is exported and the way it interacts with masks / calibration and region of interest: New graphics: Transparency, masks are transparent, only ROI is opaque Colorbar is now outside the plot for much improved readability Export image data as .mp4 and as .png image Completely new mask handling, allowing much easier mask creation / modification. Mask stay editable all the time. Much easier to create holes in masks Mask operations like shrink/grow/simplify/subdivide/optimize Automatic mask generator, capable of automatic masking of bright areas / dark aread / low-contrast areas. Possibility to add more automatic mask generators in the future Mask import (of user generated masks) heavily improved Matlab Online fully supported New line extraction and area extraction interface: More straightforward and faster. Better interaction Natural file name sorting when importing image fi...
