Abstract: A method, including collecting, during a time period from multiple computers, reports of events, each of the events including communication activity performed by a process having a respective ID and executing on one of the computers. Respective sets of features including characteristics of the activity are generated from the reports, and a model is trained for identifying, based on the features of one or more of the events, the ID of one of the processes performing the one or more of the events. An alert indicating malicious activity and referencing one or more reports of additional communication events performed by a given computer is received from a network management device, and the model is applied to the one or more reports so as to identify, on the given computer, a given ID of a given process responsible for the alert. Finally, a protective action is initiated for the given process.

Abstract: A method for depth mapping includes providing a depth mapping device comprising a projector, which is configured to project a pattern of optical radiation onto a target area over a first field of view about a projection axis, and a camera, which is configured to capture images of the target area within a second field of view, narrower than the first field of view, about a camera axis, which is offset transversely relative to the projection axis. The projector projects the pattern onto first and second planes at first and second distances from the camera, and the camera captures first and second reference images containing first and second parts of the pattern on the first and second planes, respectively. The first and second reference images are combined to produce an extended reference image including both the first and second parts of the pattern.

Abstract: One disclosed embodiment includes techniques for temperature-dependent reference image correction in structured light projectors that may be used for generating three-dimensional (3D) scene depth maps. The techniques disclosed herein include receiving an indication of a temperature (e.g., an actual current operating temperature or a change in the current operating temperature relative to an established reference temperature) associated with one or more components of a projector and then determining, based on the temperature indication, an amount of adjustment needed to correct a reference pattern image based on an estimated effective focal length change of the projector. Next, a reference pattern image may be appropriately adjusted, e.g.
