OpenCV is a library of programming functions mainly aimed at real-time computer vision. Originally developed by Intel, it was later supported by Willow Garage then Itseez (which was later acquired by Intel). The library is cross-platform and free for use under the open-source BSD license. DBSCAN (Density-Based Spatial Clustering of Applications with Noise) is a data clustering algorithm proposed by Martin Ester, Hans-Peter Kriegel, Jörg Sander and Xiaowei Xu in 1996. It is a density-based clustering algorithm: given a set of points in some space, it groups together points that are closely packed together (points with many nearby neighbors), marking as outliers points that lie alone in low-density regions (whose nearest neighbors are too far away). DBSCAN is a popular clustering algorithm and has been implemented in many data mining and machine learning packages, including R (package fpc), Python (scikit-learn), MATLAB and ELKI. OpenCV's DBSCAN services can be used to group together points in data sets, find outliers, and generate clusterings.
OpenCV is a library of computer vision algorithms and utilities. DBScan is a density-based clustering algorithm. Services are a set of functions that can be accessed by other programs or devices.
OpenCV DBSCAN services can be used to cluster data points in an efficient and effective manner. This makes it an ideal tool for data analysis and machine learning applications.
