hi i am new to Pd
welcome.
please don't use generic subjects like "help" or "i have a question". most people who write on this list either have a question or try to answer one. imagine what would happen if all of those would use the subject "help" or "answer". anyhow this is all explained at [1], which you probably should read.
i am trying to work with motion tracking in Pd I am using pix_rgba ,pix_movement,and pix-blob to get nos out of the pix_blob but when I am feeding it to a rectangle the movement is very wobbly is there any other way to track motion
[pix_movement]/[pix_blob] is just a standard way to get movement data from an image. [pix_movement2] is another. there are some openCV objects out there as well (look for pix_opencv), which might have more sophisticated tracking algorithms (e.g. based on shape).
but in all these cases: if the output signal is too noisy, you should try to reduce the noise by applying a filter: filters are the magic of tracking.
