Abstract: A method and system for translating fiducial points in multispectral imagery includes capturing a first image of an object by a first imaging device in a first spectral domain, the first spectral domain being the visible spectrum; capturing a second image of the object by a second imaging device in the first spectral domain; capturing a third image of the object by a third imaging device in a second spectral domain, the second spectral domain being outside the visible spectrum; determining three-dimensional location information of one or more fiducial points of the object based on the first and second visible spectrum images; projecting the one or more fiducial points from the three-dimensional image of the object onto an two-dimensional image plane of the third image; and translating the location of the one or more fiducial points of the object from first and second visible spectrum images to the third image.

Abstract: A computer-implemented method for training a neural network system. The method includes receiving at least a first data vector at a first layer of the neural network system; applying a function to the first data vector to generate at least a second data vector, wherein the function is based on a layer parameter of the first layer that includes at least a weight matrix of the first layer; comparing at least the first data vector and the second data vector to obtain a loss value that represents a difference between the first data vector and the second data vector; updating the layer parameter based on the loss value; and adjusting the layer parameter based on a comparison of the updated layer parameter with a threshold value of the first layer.

Abstract: Exemplary systems and methods are disclosed for removing steganography from digital data is disclosed. The method and system involve receiving a digital data. At least one processing device accesses a steganography purifier model. The at least one processing device includes at least a generator configured to scale a magnitude of individual data elements of the digital data from a first value range to a second value range. The scaled data elements are downsampled to remove steganography data embedded in the digital data and produce a purified version. The purified version is upsampled by interpolating new data elements between one or more adjacent data elements to provide an upsampled purified version. The magnitude of the data elements of the upsampled purified version are scaled from the second value range to the first value range to generate a purified output version.

Abstract: Exemplary systems and methods are disclosed for detecting embedded data in a digital image. The system includes a processing device that extracts one or more features from a digital image and analyzes the one or more extracted features in a plurality of steganography analyzers, each steganography analyzer configured to execute a different steganography algorithm. The processing device generates an output data value at each steganography analyzer, the output data value indicating a probability that the digital image includes steganography according to the steganography algorithm of the steganography analyzer. Each output probability value is fed to an ensemble classifier, the ensemble classifier including a neural network in which the output probability values of the plurality of steganography analyzers are ensembled together to generate an output ensemble data value indicating a probability that the digital image includes any steganography according to the steganography algorithms of the steganography analyzers.

Abstract: A computer-implemented method for assessing an image sentiment. The method can include receiving an image to identify a region of interest in the image; determining an image sentiment value associated with the image based on the region of interest, or a classification of the image; and displaying an indication of the image sentiment value with a spatial (e.g. geographical) location.

Abstract: A computer-automated method for securing unidirectional communication within a network. The method includes orchestrating an automated arrangement and/or coordination of at least one portion of a message using a top level orchestration server, transmitting a first data packet from the top level orchestration server to a first top level backbone server, wherein the first data packet is a first portion of the message, and authenticating the first data packet using the first top level backbone server. The method can include transmitting a second data packet from the first top level backbone server to a second top level backbone server, wherein the second data packet is a second portion of the message and/or the second data packet includes a modified first data packet, and authenticating the second data packet using the second top level backbone server.

Abstract: Disclosed is a system for updating a reference time from a decaying rotational period of a pulsar. The system can include: a database (DB) configured to store: coordinates for a pulsar; a recorded rate of rotation (RROR) for the pulsar; a rotational rate of decay (RROD) function for the pulsar; and a recorded reference time for the pulsar. A sensor can be configured to collect electromagnetic pulsar radiation from the pulsar and generate sensor data. A signal processor module can be configured to receive the sensor data, generate an observed rate of rotation (OROR) signal profile, generate a current rate of rotation (CROR) for the pulsar from the OROR signal profile, and update the RROR from the CROR. A time processor module can be configured to receive the RROD function and the CROR, and to solve the RROD function to output a reference time of the pulsar.
