Feature request: Implementing SPIFF to improve subpixel accuracy #695

Open stevenvanuytsel opened 2 years ago

stevenvanuytsel commented 2 years ago

I came across two papers (see below) which implement an algorithm to correct for the pixel-locking bias that occurs during subpixel localisation. Maybe it's worth implementing this in trackpy?
