Abstract: A system and a method for training a semantic segmentation model includes obtaining a plurality of sets of images each having an index z for visibility, iteratively training the model. Iteratively training the model includes (a) for each z above 1, obtaining preliminary semantic segmentation labels for each image of the set of images of index z?1 by applying the model to each image of the set of images of index z?1, (b) processing each preliminary semantic segmentation labels using semantic segmentation labels obtained using the model on a selected image of index 1, and obtaining processed semantic segmentation labels, (c) training the model using the set of images of index z?1 and the associated processed semantic segmentation labels, and (d) performing steps (a) to (c) for z+1.

The method of fabricating a 3-dimensional structure comprises providing a mesh formwork element such that a cavity bound by at least two opposing portions of the mesh formwork is formed; accumulating a material in the cavity; and allowing the material to harden; wherein apertures in the at least two opposing portions of the mesh formwork element are adapted to the hydro-static pressure of the accumulated material or vice versa such that at least two surfaces of the hardened material substantially take on the respective shapes defined by the two opposing portions of the mesh formwork element.

Abstract: A motion estimating device first detects mobile objects Oi and Oi? in continuous image frames T and T?, and acquires image areas Ri and Ri? corresponding to the mobile objects Oi and Oi?. Then, the motion estimating device removes the image areas Ri and Ri? corresponding to the mobile objects Oi and Oi? in the image frames T and T?, extracts corresponding point pairs Pj of feature points between the image frames T and T? from the image areas having removed the image areas Ri and Ri?, and carries out the motion estimation of the autonomous mobile machine between the image frames T and T? on the basis of the positional relationship of the corresponding point pairs Pj of feature points.

Abstract: A method and system generates 3D video images from point samples obtained from primary video data in a 3D coordinate system. Each point sample contains 3D coordinates in a 3D coordinate system, as well as colour and/or intensity information. On subsequently rendering, the point samples are modified continuously according to an updating of the 3D primary video data. The point samples are arranged in a hierarchic data structure in a manner such that each point sample is an end point, or leaf node, in a hierarchical tree, wherein the branch points in the hierarchy tree are average values of the nodes lower in the hierarchy of the tree.

Abstract: A magnetically excited, resonant cantilever sensor apparatus has a cantilever as the transducer element. A static magnetic field is directed in the plane of the cantilever(s) cooperating with a current loop in/on the latter. Orienting the magnetic field along or perpendicular to the cantilever axis and controlling the current apprpriately allows for selective excitation of resonance or non-resonance modes and/or in a self-oscillation mode. The deflection of the cantilever is detected using piezoresistive or magnetic readout. The apparatus may be used as gas sensor, scanning force microscope, mechanical filter, temperature sensor or the like.

Abstract: In order to measure a layer in the volume of a reflective structure, a transducer matrix emits at least one sonic or ultrasonic wave packet which coherently impinges on the layer. The echo signals at each element of the transducer matrix are processed separately, on the basis of determined distances between transducer elements and volume elements, and signals corresponding to the echo of each volume element on all the transducer elements of the matrix are calculated by correlation. By emitting two or more wave packets and evaluating the resulting phase or frequency difference therebetween, a two-dimensional velocity field of the structure in the layer can also be determined.
