Systems, apparatuses, and methods are presented for taking a combination of images taken synchronous in time with one another. According to one example, the present disclosure proposes one or more sensor arrays, each of which comprises multiple pixel sensors arranged to capture image data responsive to light exposure. Light is incident on the respective sensor arrays during substantially synchronous exposures. The one or more sensor arrays are configured such that the image data captured by the respective sensor arrays during the synchronous exposure differ in at least one of a luminance output or a color profile from one another.

Detection and defense system of a network credential sharing application

Systems and methods are provided for a detection and defense system relating to a network connection sharing application. For example, the system can simulate a request for a network password using a conventional application that shares this information. The application may be implemented on, for example, a mobile device or a virtual machine (VM). In some embodiments, the mobile device/VM attempts to establish a network connection to an access point (AP) using the shared password over a tunnel established between the AP and mobile device/VM. If the mobile device/VM can connect to the AP, an assumption may be made that the user credentials have been leaked and a potential security risk exists. An alert can be sent to a network administrator of the communication network (e.g., to perform an action, etc.). The action may include, for example, changing the password, removing access from one or more users, and the like.

Non-transform coding

Techniques for selectively transforming one or more coding units when coding video content are described herein. The techniques may include determining whether or not to transform a particular coding unit. The determination may be based on a difference in pixel values of the particular coding unit and/or one or more predefined rate-distortion constraints. When it is determined to not perform a transform, the particular coding unit may be coded without transforming the particular coding unit.

Using motion compensated temporal filter (MCTF) statistics for scene change detection when a fade, dissolve or cut occurs

A method is provided to better detect a scene change to provide a prediction to an encoder to enable more efficient encoding. The method uses a Motion Compensated Temporal Filter (MCTF) that provides motion estimation and is located prior to an encoder. The MCTF provides a Motion Compensated Residual (MCR) used to detect the scene change transition. When a scene is relatively stable, the MCR score is also relatively stable. However, when a scene transition is in process, the MCR score behavior changes, Algorithmically, the MCR score is used by comparing the sliding mean of the MCR score to the sliding median. This comparison highlights the transition points. In the case of a scene cut, the MCR score exhibits a distinct spike. In the case of a fade or dissolve, the MCR score exhibits a transitional period of degradation followed by recovery. By implementing the above detection using the MCR, the location of the I-pictures in the downstream encoding process can be accurately determined for the encoder.
