pairShifts.pairShifts edit page

the shifts one cross correlation pass measured between two images

Syntax

ps = pairShifts(pos,u,peak,roiSize)

The shifts measured at the tiles pos.

v = meanShift(ps,px)

Their mean length and direction in pixels.

Input

pos vector3d, the tile centres
u vector3d, how far each tile of the test image has to move to sit on the reference
peak the height of the correlation peak at each tile, which is the weight of the measurement
roiSize the tile size in pixels
px the pixel size, to state the shifts in pixels

Output

v [mean length, mean x, mean y] in pixels
