# Scene Change Detection

This demo illustrates video segmentation in time. These algorithms can be used to detect major changes in video streams, such as when a commercial begins and ends. They can be useful when editing video or when you want to skip ahead through certain content.

## Demo Model

The following figure shows the Scene Change Detection demo model:

## Scene Change Detection Results

The model segments the video using the following steps. First, it finds the edges in two consecutive video frames, which makes the algorithm less sensitive to small changes. Based on these edges, the model uses the Block Processing block to compare sections of the video frames to one another. If the number of different sections exceeds a specified threshold, the demo determines that the scene has changed.

## Available Demo Versions

Windows® only: vipscenechange_win.mdl

Platform independent: vipscenechange_all.mdl

Windows-only demo models might contain compressed multimedia files or To Video Display blocks, both of which are only supported on Windows platforms. The To Video Display block supports code generation, and its performance is optimized for Windows.
