I don't have a recommendation for the calibration pattern size, but I will mention that the dot pattern grids seem to lead to a more accurate calibration than the checkerboard...
Hi Wei-Meng515, 1. There are second order polynomial shape functions available, but there isn't an option in the GUI to use them. You have to manually add a line to...

Not currently, but if we do write one, I'll link to it here.
The regularization constant is the weight added the regularizing term in the formulation. In the default case, the regularization is a Horn-Schunk type smoothing of the gradient of the displacement...
The gauss filter image parameter applies a Gaussian filter to the images prior to doing the DIC, the value of the filter is the size of the filter window.
Regarding the variation in thresholding between the left and right camera, it seems like we should enable the user to select a separate threshold for the left and right camera....
I guess if changing the initialization routine helped, you don't need to upload the cal file. Glad that helped. Feel free to add the separate thresholding option as a feature...
