Blob
tracking.

A visual study where colour, motion, and connected regions turn a moving image into a living field of points and trails.

The idea

I wanted to treat a moving image as a set of living shapes. Colour regions become blobs, and their movement gives the frame a new kind of drawing.

How it works

The image is separated into colour ranges, connected regions are found, and their positions become the structure for lines, boxes, labels, and trails. Small changes in the source create a constantly shifting composition.

What’s inside

  • Colour thresholding and connected components
  • Tracked centres, bounds, and motion trails
  • Adjustable colour ranges and blob size
  • Still-image and video exports

Where it could go

A starting point for reactive visuals, live camera treatments, and graphic systems that follow movement without trying to reproduce the original image.
