Abstract: Disclosed is an imaging device for AMI diagnosis includes a first polarizer is arranged in an imaging part and a second polarizer is arranged in a light source part. These two are linear polarizers, and the polarization directions of the first polarizer and the second polarizer are perpendicular to each other. During the imaging process, a near-infrared beam emitted from a near-infrared light source is modulated into a linearly polarized light with a certain angle when passing through the second polarizer. Then, it is irradiated onto a subject and the light is reflected due to the specular reflection effect of the subject turns into a cross-polarized light when passing through the first polarizer. The linearly polarized light perpendicular to the polarization angle of the first polarizer is intercepted, that is, the reflected light is intercepted.

Abstract: Techniques for a flexible data security and machine learning system for merging third-party data are provided. In one technique, the system receives a data set from a third-party entity and receives selection data that indicates that the third-party entity selected a set of data security policies that includes an encryption option and a data mixing option from among multiple data mixing options. In response to receiving the selection data, the system stores data that associates the set of data security policies with the data set, encrypts the data set according to the encryption option, and persistently stores the encrypted data set. Later, the system decrypts the encrypted data set in volatile memory, generates, based on the data mixing option, training data based on the decrypted version of the data set, trains a machine-learned model based on the training data, and stores the machine-learned model in association with the data set.
