Hi, Eleanor
- make sure to use the latest pix_multiblob from recent Gem Git as the older version doensn't work properly for blobs greater than 10.000 pixels (eg, 100x100).
- not sure I understood your question, actually. isn't that 'argument' the maximum number of blobs? also, the minimum blob area can be set and is a very useful filter.
- note that detection of a blob, which is what pix_multiblob does, is not the same as tracking. Traking inolves detecting consistent blob id's across frames, which is not done in pix_multiblob. Ways to do tracking would involve combining pix_multiblob with color detection (like the new pix_colorclassify), the color being the consistent id itself, or just being used as part of a blob similarity function based on things such as such as color histograms (pix_opencv_meanshift would be a standard tracking approach along those lines).
hope this helps,
