Vis-O-Matic image analysis tools

Powerful image analysis, right in your browser.

Vis-O-Matic is a free suite of tools for working with image datasets. Organise and curate them in Image Manager, cut regions out with Image Cutter, measure colour with the Batch Image Analyzer, plot the results in Image Visualizer, and register 360° frames to true north with SunSync 360. Group your work into a project and it carries across all five.

▦ Projects Hub where your work is kept

A project keeps one body of work together — the image datasets, everything the tools produce from them, and a record of what was run. Start one here, then open it in any tool.
