Abstract:
An efficient approach for estimating scalefactors for use in the quantization of audio signal spectrum values is described. The scalefactor estimation approach can be implemented in multiple stages. A first stage estimates a distortion level for a selected scalefactor band spectrum value based on a received maximum tolerant distortion threshold and the spectrum values in the scalefactor band. A second stage determines an interim process value based on the previously estimated distortion level and generates a scalefactor for a selected scalefactor band spectrum value based on the generated interim process value and a statistically predetermined fraction. A third stage generates a scalefactor that applies to the whole scalefactor band based on the scalefactor generated for the selected scalefactor band spectrum value. The approach provides a performance gain of 40% over previous techniques, thereby reducing device power requirements and audio encoder bottlenecks.
Abstract:
Technologies for location privacy management include a mobile computing device to determine whether an application is authorized to obtain the location of the mobile computing device based on a determined location and location access policy of the mobile computing device. The location access policy includes policy rules that identify whether the application is authorized to obtain the location of the mobile computing device. If the mobile computing device determines that the application is not authorized to obtain the location of the mobile computing device, the mobile computing device blocks the application from obtaining the location.
Abstract:
System and methods are provided for dynamic performance adjustment of a media playing pipeline. For example, the media playing pipeline includes one or more components synchronized for media playing. A reference component in the media playing pipeline is selected, the reference component having a component performance level. A pipeline performance level of the media playing pipeline is determined. When the pipeline performance level is higher than a threshold, the component performance level of the reference component is adjusted to decrease the pipeline performance level. When the pipeline performance level is lower than the threshold, the component performance level of the reference component is adjusted to increase the pipeline performance level.
Abstract:
A method of processing an image includes the steps of receiving selection of the first region of interest (ROI) of an image, processing the first image data related to the first ROI, displaying the first image ROI based on the first image data, receiving selection of the second ROI of the image, which at least partially overlapping the first ROI, processing the second image data related to a portion of the second ROI that does not overlap the first ROI, combining the processed second image data with the processed first image data that overlaps the second ROI, and displaying the second image ROI based on the combined processed second image data and the processed first data.
