the shifts one cross correlation pass measured between two images

Syntax

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

The tile centres, their shifts, peaks and width.

v = ps.meanShift(px)

[mean length, mean x, mean y] in pixels of size px.

ps.isempty

Whether nothing was measured.

Description

What the trueEbsd job keeps of every pass of xcfShift between a pair of images: the tile centres, how far each tile of the test image has to move to sit on the reference, the correlation peak height of every tile, the weight of the measurement, and the tile size. meanShift states the mean shift over the tiles measured in pixels.

Input

pos vector3d, the tile centres
u vector3d, the shift of every tile
peak the correlation peak height of every tile
roiSize the tile size in pixels

Output

ps pairShifts

meanShift the mean shift in pixels of size px over the tiles measured, [mean length, mean x, mean y]
