IMAQ RemoveParticle vs. IMAQ Morphology

[BeKo]

I have a comparison between "IMAQ Remove Particle" and "IMAQ Morphology". If I choose the same attitude (Structuring element, etc.) in"IMAQ Morpholoy" and "IMAQ RemoveParticle" should deliver the same results?
In "IMAQ Morphology" removes not only the undesirable backround particle, also a little bit of the circle. It is logical to me. But "IMAQ Remove Particle" doesn't remove something from the circle ? Where is the difference?

Your question is not clear to me.Who told you that erosion and remove particle is the same?

Hi, BeKo,

The first difference that IMAQ Remove Particle will not change the shapes of the particles which are kept. They remain exactly the same shape as those found in the original source image. IMAQ Morphology (Erode operator) will change shapes of all particles (and small particles will be disappear, of course).

The only question: which particles will be removed by IMAQ Remove Particle and IMAQ Morphology (Erode operator). If inside of IMAQ Remove Particle NI has used Morhology, then both should be the same. But may be not. You can do simple test yourself - just prepare test image with different shapes of the particles, perform both opearions and compare results.

Thanks for the answer.

I thougth IMAQ RemoveParticle and IMAQ Morpholoy work in the same way.

I don't find further information for IMAQ RemoveParticle in the NI Vison concepts.
