摘要： A predictively-coded object-based picture signal representing a group of pictures is transcoded into a predictively-coded block-based picture signal representing the group of pictures by extracting a coded scene descriptor and coded object descriptors from the predictively-coded object-based picture signal. The coded scene descriptor is decoded to generate a scene descriptor. The coded object descriptors are partially decoded to generate respective partially-decoded object descriptors. The decoding extracts coding information that describes the predictive coding of the coded object descriptors. In response to the scene descriptor, a frame of a partially-encoded block-based picture signal representing one of the pictures as a current picture is generated from the partially-decoded object descriptors. Finally, a frame of the predictively-coded block-based picture signal representing the current picture is generated by predictively coding the partially-coded block-based picture signal to a uniform coding state in response to the coding information.

摘要： At least one camera lens captures a field of view comprising at least one object of interest, wherein the at least one camera lens is configured for extending the field of view in at least one direction. The at least one object of interest that is within said field of view is detected. Then, an image of a detected at least one object of interest is warped to fit within the field of view. A plurality of pixels surrounding the image of the detected at least one object of interest within the field of view is cropped such that, based on the warping and the cropping, the detected at least one object appears as centered within the field of view.

摘要： A method for scaling a progressively encrypted sequence of scalable data is disclosed. The method includes associating data with the progressively encrypted sequence of scalable data that identifies combinable portions of the progressively encrypted sequence of scalable data to combine in order to produce a scaled version of the progressively encrypted sequence of scalable data. The scaled version of the progressively encrypted sequence of scalable data is scaled to possess a desired scalable attribute. Moreover, the scaled version of the progressively encrypted sequence of scalable data is scaled without being decoded. A cryptographic checksum is computed for at least one combinable portion of the progressively encrypted sequence of scalable data and, a cryptographic checksum is associated with the at least one combinable portion of the progressively encrypted sequence of scalable data.
