Authentication risk-scoring in an authentication system based on user-specific and organization-specific risk models
An authentication system uses machine learning models to quantify a degree of risk that a given request to authenticate as a particular user of an organization is not in fact originating from that user, but rather from a malicious actor attempting to gain access to the user's account.

HDMI matrix switcher receiving side and receiver-side fiber connector power management
In an HDMI (High Definition Multimedia Interface) video signal transmission system in which a fiber optic cable connects the HDMI transmitter and receiver, the HDMI receiver supplies a DC power to the receiver-side connector of the fiber optic cable on a designated pin of the HDMI interface, such as pin 14 of the Type A interface.

Image processing device, method, image reading device, and recording medium
A local variance or an edge amount is calculated as an image feature amount by analyzing a reference image of the same field of view as multiple band images constituting a multispectral image, a filter parameter is calculated from the image feature amount, and smoothing the band images while preserving edges is performed by using the filter parameter. When a multispectral image including a band image of a wavelength band in which a sufficient signal amount is not obtained is obtained, it is possible to improve the S/N ratio of the multispectral image without destroying edges. |

Single image deraining method and system thereof
A single image deraining method is proposed. A wavelet transforming step processes an initial rain image to generate an i-th stage low-frequency rain image and a plurality of i-th stage high-frequency rain images. An image deraining step inputs the i-th stage low-frequency rain image to a low-frequency deraining model to output an i-th stage low-frequency derain image. A first inverse wavelet transforming step recombines the n-th stage low-frequency derain image with the n-th stage high-frequency derain images to form an n-th stage derain image. A weighted blending step blends a (n−1)-th stage low-frequency derain image with the n-th stage derain image to generate a (n−1)-th stage blended derain image. A second inverse wavelet transforming step recombines the (n−1)-th stage high-frequency derain images with the (n−1)-th stage blended derain image to form a (n−1)-th stage derain image, and sets n to n−1 and repeats the last two steps. |
