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, On Tuesday, November 29, 2011, Eleanor Stewart <[email protected]> wrote: > Thanks Hans, > > Yep, I've been working my way through the 'help' patches. > I'm currently exploring pix_multiblob but it's not tracking as I thought it would. > When it has an 'argument' to track 2 (or more) 'blobs', it still only tracks 1 'blob'. > > Does anyone know if it's 'argument' value only relates to the amount of representations that can be applied to 1 'blob' being tracked? > > Thanks, > mz_multiblob ^^ > > -- Ricardo Fabbri -- Linux registered user #175401 www.lems.brown.edu/~rfabbri labmacambira.sf.net
