ParticleSet
objectPerforms linking of the particles by tracking them through the frames
link.particles( particleset, L, R = 2, epsilon1 = 0.1, epsilon2 = 2, lambda1 = 1, lambda2 = 1, penaltyFunction = penaltyFunctionGenerator(), verboseOutput = FALSE, prog = FALSE, include.intensity = TRUE, include.area = FALSE )
particleset |
A |
L |
Maximum number of pixels an object can move in two consecutive frames |
R |
Linkrange, i.e. the number of consecutive frames to search for potential candidate links |
epsilon1 |
A numeric value, to be used in the formula. Jitter for allowing angular displacements |
epsilon2 |
A numeric value, to be used in the formula. Jitter for allowing spatial displacements |
lambda1 |
A numeric value. Multiplicative factor for the penalty function |
lambda2 |
A numeric value. Multiplicative factor applied to the angular displacement |
penaltyFunction |
A function structured in such a way to be applied as penalty function in the linking |
verboseOutput |
Logical, whether the output should report additional intermediate steps. For debugging use mainly |
prog |
Logical, whether the a progress bar should be shown during the tracking phase |
include.intensity |
Logical, whether to include also intensity change of the particles in the cost function calculation |
include.area |
Logical, whether to include also area change of the particles in the cost function calculation |
