Abstract: A method for generating a Sequence Parameter Set and a Picture Parameter Set for decoding an H.264 coded video file fragment is provided. The method includes identifying a start of frame data, creating a parameter dictionary, detecting an entropy coding-mode, updating the parameter dictionary, identifying a plurality of headers, and verifying a generated picture.

Abstract: The present disclosure provides new and innovative systems and methods for profiling bias for data sources, specifically publishers of news articles. A variety of embodiments include a computer-implemented method for profiling a data source includes obtaining an indication of a first data source, determining visitor and keyword data for the first data source, determining metadata for the first data source, generating a source similarity graph for the first data source, the source similarity graph indicating at least one similar data source and, for each similar data source, a bias score for the similar data source, classifying the first data source based on the bias scores for the at least one similar data source, generating a notification indicating the first data source and the classification of the first data source, and providing the notification.

Abstract: Several promising techniques have been recently proposed to bind an image or video to its source acquisition device. These techniques have been intensively studied to address performance issues, but the computational efficiency aspect has not been given due consideration. Considering very large databases, the efficiency of the sensor fingerprint based source device identification technique is described. Novel schemes that improve search complexity as compared to a conventional approach are described.

Abstract: Host malware (or change) may be detected by (1) receiving baseline set of response time information for each of one or more transactions involving (A) the host and (B) at least one peer of the host, (2) determining or receiving a later set of response time information for each of the one or more transactions involving the host and the at least one peer of the host, and (3) determining whether or not host slowdown has occurred using the baseline set of response time information and the later set of response time information. The execution of a host malware (or change) protection policy may be controlled using at least the determination of whether or not host slowdown has occurred.
