Abstract: A method and an arrangement for producing a workpiece using additive manufacturing techniques involve pre-process, in-process and post-process measurement in order to determine individual characteristics of one or more workpiece layers. In particular, dimensional and/or geometrical characteristics of a workpiece layer are measured before the next workpiece layer is produced. Advantageously, production parameters are controlled in response to individual material characteristics determined prior to the production process. Also advantageously, measurement results are fed back into a production process in order to increase accuracy, reliability, repeatability and precision of the production process.

Abstract: A method for the computer-assisted configuration of a data-driven model on the basis of training data is provided. The method is characterised in that the series of measurements are subjected to a suitable preprocessing process comprising a binning step, wherein measurement characteristics which existed during the measurement of the measurement values in question are taken into consideration. A suitable data-driven model such as a neural network is then learned on the basis of the pre-processed series of measurements. This learned data-driven model makes it possible to accurately forecast target vectors in accordance with associated series of measurements. The method can, for example, be used to analyse optical spectra. More particularly, it is possible to predict using the learned model whether the tissue sample for which an optical spectrum was detected represents diseased tissue.

Abstract: In one embodiment, a method receives spherical content for video and generates face images from the spherical content to represent an image in the video. A two dimensional sheet for the face images is generated. A size of the face images is reduced and a pixel frame around each of the plurality of face images is added on the sheet. Also, a plurality of gaps are added on the sheet in between edges of the face images that are neighboring. The method then adds gap content in the plurality of gaps where the gap content is based on content in an area proximate to the plurality of gaps. The method encodes the face images, the pixel frame, and gap content on the sheet and sends the encoded sheet to a decoder. The face images are decoded for placement on an object structure to display the spherical content.
