| Post subject: | minimun blob size in ExtractBlobs |
dear forum, I would like to ask some ideas about how I could eliminate small blobs from the list given by ExtractBlobs. I mean, I would like to eliminate them before calling ExtractBlobs, not after. I know I can get blob info with ExtractBlob2DInfo but I don't see how to loop throught the list of blobs (output of ExtractBlobs) and delete all the blobs smaller then a determined area. thank you, andrei |

Hi, you can use the ListRemoveIf block, which removes blobs which area is not in the specified range. Keep into account the fact that this block uses normalized area, thus, a blob with area spans the whole image. Paolo |
