Mean Shift is a clustering algorithm that is particularly effective in identifying modes or clusters within a dataset. It operates by locating areas of higher data point density and building clusters around these regions. The algorithm uses a kernel density estimation (KDE) approach, where a kernel is placed at each data point, and the algorithm iteratively shifts these kernels towards the densest areas of the data until convergence is achieved.

One of the key advantages of Mean Shift is its ability to handle arbitrary-shaped clusters, making it versatile for various applications, including satellite image segmentation and object tracking. The algorithm is visualized using the skyscraper skyline analogy, where the skyscrapers represent data points, and the clusters are formed around the taller buildings, indicating higher density areas ¹².

In the context of computer vision, Mean Shift is often used for object tracking, as it can efficiently track objects based on color data, even when they change orientation or distance from the camera ⁴. This makes it a valuable tool in real-time applications where quick identification and tracking of moving objects are required.
