Getting started

What Praxis is

Praxis provides hosted video analysis and local tools for multi-view review, 3D context, and model evaluation. These docs separate working routes from prepared examples and runtime design records.

Video review loses context when timestamps, subject histories, decisions, and exports live in separate tools. Mission Studio keeps an operator-defined question, its processing stages, the matching events, and their evidence in one project record.

The product pipeline ingests video, detects and tracks objects, evaluates spatial rules, and produces event records with supporting evidence. Mission Studio runs this pipeline on a bounded hosted CPU worker. Other public routes use browser code or recorded source data and state that boundary in their interface.

Use the public software#

Five product routes are available without an account. Each one includes its data source and operating boundary in the interface and in the software record.

Mission Studio

Run a short video through detection, identity tracking, one operator rule, and retained output.

Memory

Align two to four local recordings, add operator-confirmed links, and export the case record.

World

Open a local point cloud and optional camera path, or inspect the bundled reconstruction example.

Watch Areas

Save a fixed-camera area rule and apply it to footage, or inspect the registered aerial example.

Model Arena

Score two to four local detection results against ground truth and inspect exact error frames.

The shape of the system#

The documented product model reduces to one flow:

feed→objects→zones + rules→events→evidence

Each stage is documented on its own page. If you read nothing else, read Zones and Rules & events. They carry most of the ideas.

Start here#

Mission Studio guide

Configure footage, run the five processing stages, inspect events, and export the Evidence Pack.

Zones

Watch areas anchored to the world, not the screen. The camera moves, the zone doesn't.

API overview

Create projects, upload sources, save objectives, run compute, and retrieve retained evidence.

The challenge

Count cars entering a zone by hand, then compare with a prepared result record.

Product routes#

Product map

See how Vision, Watch Areas, Memory, Mission Studio, World, and Model Arena fit together.

Watch Areas

Inspect the area-entry data and the method behind it.

Mission Studio and API v1 use the hosted analysis worker. Memory, World, and Model Arena run local browser workflows on operator-selected files. Prepared examples remain labeled as examples.
