How does mean shift tracking work?

Like most other clustering algorithms, the mean shift algorithm attempts to look for places in the data set with a high concentration of data points, or clusters. The algorithm places a kernel at each data point and sums them together to make a Kernel Density Estimation (KDE).

What is mean shift clustering?

Mean shift clustering algorithm is a centroid-based algorithm that helps in various use cases of unsupervised learning. It is one of the best algorithms to be used in image processing and computer vision. It works by shifting data points towards centroids to be the mean of other points in the region.

What is mean shift in statistics?

Mean shift is a procedure for locating the maxima—the modes—of a density function given discrete data sampled from that function. This is an iterative method, and we start with an initial estimate . Let a kernel function be given. This function determines the weight of nearby points for re-estimation of the mean.

What is mean shift segmentation?

Mean shift is an unsupervised learning algorithm that is mostly used for clustering. It is widely used in real-world data analysis (e.g., image segmentation)because it's non-parametric and doesn't require any predefined shape of the clusters in the feature space.
