How Do We Analyze Video with AI
People & Blogs
Introduction
In today's rapidly advancing technological landscape, video analysis using artificial intelligence (AI) has become increasingly essential across various applications. Three primary functions that AI can perform in video analysis are motion detection, object tracking, and action recognition.
Motion Detection
Motion detection is a fundamental aspect of video analysis that allows us to identify movement within a video over time. It essentially answers the question: is anything moving in this video? For instance, in a security video, we can determine if there is any movement within a specific masked region. The process involves providing the model with a video and a polygon mask to indicate the detection area. As output, the model generates a motion label along with a confidence score for each frame.
This technology finds utility in various scenarios, such as:
- Detecting people moving in surveillance videos.
- Monitoring wildlife movement on a game preserve.
- Assisting collaborative robots in detecting humans within their workspace.
Object Tracking
Object tracking enables us to follow the movement of an object over time, effectively answering the question: how are these objects moving? By inputting a video into the model, it produces a sequence of bounding boxes alongside the corresponding object ID for each tracked object.
The applications of object tracking are diverse, including:
- Tracking individuals walking in surveillance footage.
- Following the faces of participants during video calls.
- Avoiding pedestrians in self-driving cars.
Action Recognition
Also referred to as activity detection, action recognition allows us to classify various actions occurring in a video, providing insight into the question: what’s happening in this video? By supplying the model with a video depicting multiple human activities, it outputs an activity label along with a confidence score.
This function is essential for different contexts, such as:
- Identifying unlawful activities in surveillance videos.
- Analyzing sports actions in relevant footage.
- Facilitating collaboration between humans and robots.

FAQ
Q1: What is motion detection in video analysis?
A1: Motion detection identifies movement in a video over time, indicating whether anything is moving in a specified area.
Q2: How is object tracking different from motion detection?
A2: While motion detection identifies whether there is movement, object tracking follows the specific movement of tracked objects over time.
Q3: What is action recognition?
A3: Action recognition classifies various actions occurring in a video, helping to understand what is happening in that footage.
Q4: Where is AI video analysis commonly used?
A4: AI video analysis is used in surveillance, wildlife monitoring, collaborative robotics, sports analysis, and more.
