Detection and prevention of unwanted content on cloud-hosted services
The problem of abuse of privileges at cloud-hosted service sites is addressed at the sign-up stage by identifying suspicious or abusive users and preventing them from signing up in the first place. This approach may utilize a relatively small initial data set based on the recognition that while abusers' profiles are mutable and difficult to characterize stably—abusers will deliberately shift their usage patterns to evade detection—a site's legitimate users tend to have similar and stable characteristics; that is, such characteristics are “cohesive” across cloud-hosted service (e.g., social media) sites and their users. The information gleaned from analysis of this small data set can be applied to a much larger, unsorted data set to obtain profiling criteria based on a large population for statistical reliability. |

Various applications address the issue of the limited screen size of mobile devices by using the motion sensors of the devices both to move from one part of a program to another, thus eliminating the need for on-screen navigation buttons and allowing the entire screen to be used for content, and also to reinforce learning through the use of mnemonics. In these applications, the user rotates the device after completing each step, in sequence, of a process-based series of problem solving techniques. Group learning dynamics are also reproduced through a study group feature. |

Color document image segmentation and binarization using automatic inpainting
A method for separating foreground and background contents in a document image is provided. The method first computes a pixel-wise map of maximal local features (e.g., local variance, local contrast, etc.), which is binarized to generate a mask for potential foreground.

Post-processing of the binary foreground image can further remove undesirable elements. Finally, a more accurate background image can be obtained by inpainting the original document image using the binary foreground image as a mask. |

The network interface may be configured to receive signals over channels, where the signals include at least one local network signal, e.g. a signal originating on a local network, and at least one non-local network signal, e.g. a signal originating on a non-local network. The power level detector may be configured to determine attenuation values of the received signals. The signal processor may be configured to discard a first signal and reallocate the channel over which the first signal was received, without processing the first signal in a frequency domain, when the attenuation value of the first signal fails to satisfy a signal threshold. In one or more implementations, the signal threshold may differentiate the local network signal from the non-local network signal based at least in part on the determined attenuation values. |
