Abstract: In one aspect, multiscale filtering is used to normalize the intensities of voxels in an MRI image. A multiscale filter is applied to the raw MRI image. This image is compared to the original image. Luma aberrations (i.e., intensity variations) are corrected based on this comparison. In one approach, the intensity of the image is increased for voxels that are dimmer than in the multiscale filtered version, and decreased for voxels that are brighter than the multiscale filtered version. In another aspect, additional features are created based on multiscale gradients. These may be used in combination with other approaches to segment the MRI image. Voxels with positive gradients may represent brain gray matter bordered by brain white matter. Voxels with negative gradients may represent brain white matter bordered by brain grain matter.

Abstract: A device receives, as part of a gesture translation service, data that depicts gestures, wherein the data is image data or multimedia data. The device converts a set of frames that include the data to another set of frames that include modified data identifying a grayscale or black and white depiction of the gestures and generates graphical representations of the gestures identified by the modified data. The device selects, using a matching technique, a graphical representation of corresponding gestures that matches or satisfies a threshold level of similarity with the graphical representations of the gestures identified by the modified data. The device identifies response data that is representative of the corresponding gestures based on the response data being stored in association with an identifier of the graphical representation that has been selected. The device provides the response data to be displayed, via an interface, as text data or audio data.
