## Cancel Analysis

Cancel the currently running analysis. This option is available (and replaces all other options) only when analysis is running. *** ## Run 2D

Detect people in each of the loaded videos. When complete, boxes are drawn around the detected people in the video overlays if Show Boxes is selected in the Display menu. Video data and calibration must be loaded before running ***Run 2D***. *** ## Track People

Identify people across views (i.e., determine “who is who” in each of the views). Identification requires the person to be clearly visible in at least three views simultaneously. Each identified person is assigned a unique color that is applied to their boxes, segments, and skeleton. ***Run 2D*** must be completed before running ***Track People***. If a workspace is loaded or the loaded trial has been processed, ***Track People*** can be used to update the person tracking results after modifying person tracking settings without requiring the full analysis. These settings include those under the ***People*** tab of the [Analysis Preferences](/theia3d-documentation/theia3d-dropdown-menus/settings-menu/analysis-preferences.md) *** ## Solve Skeleton

Solve the 3D pose of each identified person. The kinematic model is scaled and the pose of the model is solved using inverse kinematics. A description of the model can be found in [Theia Model Description](/theia3d-documentation/theia-model-description.md). Refer to [Settings Menu](/theia3d-documentation/theia3d-dropdown-menus/settings-menu.md) for information about using a previously saved model to perform the inverse kinematics step. ***Track People*** must be complete before running ***Solve Skeleton***. If a workspace is loaded or the loaded trial has been processed, ***Solve Skeleton*** can be used to update the pose results after modifying inverse kinematic pose solution settings without requiring the full analysis. These settings include those under the ***Skeleton*** tab of the [Analysis Preferences](/theia3d-documentation/theia3d-dropdown-menus/settings-menu/analysis-preferences.md). *** ## Run Analysis (without 2D)

Runs: ***Track People*** and ***Solve Skeleton***. ***Run 2D*** must be completed before using ***Run Analysis (without 2D).*** *** ## Run Analysis

**Shortcut: Ctrl + F** Runs: ***Run 2D***, ***Track People***, and ***Solve Skeleton***. Video data and calibration must be loaded. {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.
