Abstract: Disclosed herein are scientific-instrument support systems, as well as related methods, apparatus, computing devices, and computer-readable media. In some embodiments, a support apparatus for a scientific instrument includes an interface device and a processing device. The interface device receives Ronchigrams acquired with the scientific instrument and transmits control signals for the electron-beam optics thereof. The processing device converts a measured Ronchigram into an input token for a transformer, produces an output token based on a tokenized sentence ending with the input token, and determines adjustments to the control signals based on the input and output tokens. The input and output tokens belong to a plurality of tokens representing reference Ronchigrams sampling an alignment parameter space of the electron-beam optics.

Abstract: A method for recognition and/or verification of authenticity of digital, and/or physical objects, comprising the steps of codebook training, object enrollment, and object verification, the latter consisting in object recognition and/or object authentication. The method uses two types of features, of codebooks, and of databases, which are specifically designed for identification, respectively authentication, the identification database and authentication database having different organizations. The invention is also directed to corresponding computer program means adapted to implement the proposed method, devices adapted for implementation of a method, as well as to applications which are particularly adapted for use of the proposed method.
