According to parameters of interests, such as size, eccentricity/shape, filters out the particles that do not satisfy the indicated requirements
select.particles(particleset, min.area = 1, max.area = 1000)A ParticleSet object. A LinkedParticleSet object can also be provided as input, yet the returned object will be a ParticleSet object that needs to be linked again
Size in pixels of the minimum area needed to detect the object as a potential particle of interest
Size in pixels of the maximum area allowed to detect the object as a potential particle of interest
A ParticleSet object
