Blob Track with second input 'background image'

General TouchDesigner Discussion

Hi,

when i use blob track TOP with just 1 input the blobs are always square, however when I use the second input for ‘background image’ the blobs show as rectangles.

Is there a way to keep the blobs as squares when also using the second input? I am using a top down blob track system for interactive floor projection but when blobs are rectangular they overlap and disappear much more frequently

Hi @retone,

while this is not an option, you could choose the width or height values from the Info DAT to construct a square boundary around the blob.

cheers
