I just started manipulating images. I tried to obtain the velocity field using JPIV.
This question is similar to a post titled "Image processing area" at 2017-08-01.
I processed images of 1500 x 1300. Output data jvc file has data in the range (64, 64) to (1344, 1216). Interrogation window is 128x128 at first pass, and at 3pass, width is 16x16.
I think this gap is considerably larger than half of the window width.
I also analyzed even smaller images with PIV. However, I thought that the gap was large like above case.
What is the cause of this situation? Which parameters in the configuration window are involved?
Thank you.
