Glossary
DCT discrete cosine transform FFT fast Fourier transform FOV field of view, the region of the environment that an image sensor observes. ROI region of interest, an image patch that is likely to contain relevant information. skeletonisation process of shrinking a shape to a connected sequence of lines, which are equidistant to the boundaries of the shape. SNR signal-to-noise ratio VOI volume of interest, a cuboid that encloses three-dimensional [3D] data points that are likely to represent relevant information
