Abstract
Several methods and systems for masking multimedia data are disclosed. In an embodiment, a method for masking includes performing a prediction for at least one multimedia data block based on a prediction mode of a plurality of prediction modes. The at least one multimedia data block is associated with a region of interest (ROI). A residual multimedia data associated with the at least one multimedia data block is generated based on the prediction. A quantization of the residual multimedia data is performed based on a quantization parameter (QP) value. The QP value is variable such that varying the QP value controls a degree of masking of the ROI.
Claims20
A computer implemented method of masking multimedia data, the method comprising:
- performing a prediction for at least one multimedia data block based on a prediction mode of a plurality of prediction modes, the at least one multimedia data block being associated with a region of interest (ROI);
- generating a residual multimedia data associated with the at least one multimedia data block based on the prediction;
- and
- performing a quantization of the residual multimedia data based on a quantization parameter (QP) value, the QP value being variable such that varying the QP value controls a degree of masking of the ROI.
A system for masking multimedia data comprising:
- a prediction module configured to:
- perform a prediction for at least one multimedia data block based on a prediction mode of a plurality of prediction modes, the at least one multimedia data block being associated with a region of interest (ROI), and
- generate a residual multimedia data associated with the at least one multimedia data block based on the prediction;
- and
- a quantization module communicatively associated with the prediction module, the quantization module configured to perform a quantization of the residual multimedia data based on a quantization parameter (QP) value, the QP value being variable such that varying the QP value controls a degree of masking of the ROI.
An integrated circuit comprising:
- a transceiver module communicatively associated with a plurality of multimedia resources and configured to receive multimedia data from a multimedia resource;
- a multimedia processing module communicatively associated with the transceiver module and configured to perform masking of the multimedia data, the multimedia processing module comprising:
- a prediction module configured to:
- perform a prediction for at least one multimedia data block based on a prediction mode of a plurality of prediction modes, the at least one multimedia data block being associated with a region of interest (ROI), and
- generate a residual multimedia data associated with the at least one multimedia data block based on the prediction, and
- a quantization module communicatively associated with the prediction module, the quantization module configured to perform a quantization of the residual multimedia data based on a QP value, the QP being variable such that a varying the QP value controls a degree of masking of the ROI;
- and
- a memory module communicatively associated with the transceiver module and the multimedia processing module and configured to store the multimedia data subsequent to the masking of multimedia data.
