BoofCV - an open source Java library for real-time computer vision applications

I came across this recently and , seems like a must consider open source library (like opencv).

"BoofCV is organized into several packages: image processing, features, geometric vision, calibration, visualize, and IO. Image processingcontains commonly used image processing functions which operate directly on pixels. Features contains feature extraction algorithms for use in higher level operations. Calibration has routines for determining the camera's intrinsic and extrinsic parameters. Geometric vision is composed of routines for processing extracted image features using 2D and 3D geometry. Visualize has routines for rendering and displaying extracted features. 'IO stands for input/output and contains common routines for reading in images from various input source " [1]
