The Image data structure is implemented as a 2D or 3D array and can be directly converted to a numpy array. A pair of depth and color images of the same resolution can be combined into a data structure named RGBDImage. Since there is no standard depth image format, we have imple-mented depth image support for multiple datasets including

•NumPy arrays have a ﬁxed size at creation, unlike Python lists (which can grow dynamically). Changing the size of an ndarray will create a new array and delete the original. •The elements in a NumPy array are all required to be of the same data type, and thus will be the same size in memory.
