WebMean shift is a non-parametric feature-space mathematical analysis technique for locating the maxima of a density function, a so-called mode-seeking algorithm. Application domains include cluster analysis in computer vision and image processing . Variants of the algorithm can be found in machine learning and image processing packages: • ELKI. Java data mining tool with many clustering algorithms. • ImageJ. Image filtering using the mean shift filter. • mlpack. Efficient dual-tree algorithm-based implementation. free vehicle maintenance report
