Construct intensity profile for a given particle trajectory
Description
Construct intensity profile with structure 'T_SS_mat' for a given particle trajectory, background intensity profile, and user defined radius of particle.
Usage
fill_intensity(len_t, M, I, pos, Ic, sz, sigma_p)
Arguments
len_t |
number of time steps |
M |
number of particles |
I |
background intensity profile. See 'Details'. |
pos |
position matrix for particle trajectory |
Ic |
vector of maximum intensity of each particle |
sz |
frame size of simulated square image |
sigma_p |
radius of the spherical particle (3sigma_p) |
Details
