Design a fast path to real-time image labeling with a hardware-optimized connected components algorithm.

This nonfiction field guide explains a method to compute component numbers for each pixel on the fly using a compact bracket table and simple pushdown stacks, enabling high-speed hardware realization. The book details a hardware implementation of a proven algorithm for binary images and describes how a prototype board achieves video-rate performance on 512x512 images.

Two main sections describe the algorithm and its hardware realization. It explains how two passes over the image assign groupings and final component labels, and how bracket marking and stack management track connectivity. It also discusses design choices for speed, such as pipelining, parallel modules, and potential VLSI implementations. Real-world results include a working Connected Components Board that labels a 512x512 binary image in a few video frames, with performance suitable for real-time imaging tasks.
What you’ll learn

How bracket marking and pushdown stacks model connectivity across image rows.
Two-pass processing: building groups on the way down and assigning labels on the way up.
Hardware design considerations for speed, including pipelining and modular organization.
Practical performance details of a prototype board under real-time conditions.

Ideal for readers of hardware design for image processing and researchers exploring real-time robot vision applications.
