1. A method of executing a wavelet transform on masked data, the method executed under the control of a processor configured with computer executable instructions, the method comprising: shuffling, by a system having one or more processors, an unmasked indication associated with a focus input value of a high-pass wavelet filter, to a location in a wavelet filter output mask layer associated with a result of a low-pass wavelet filter; and encoding, by the system, mask information of the masked data and quantized unmasked results of the wavelet transform.
