  • Patent number: 11889052
    Abstract: A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted. At the generating of the prediction information, the prediction information is generated by using the information on the coding unit neighboring to the current coding unit.

  • Patent number: 11877828
    Abstract: Systems and methods are disclosed that facilitate the reduction of both radio frequency (RF) noise and photoacoustic artefacts in differential photoacoustic radar imaging through a multi-step electrical and optical domain calibration method. An example two-step calibration method involves reducing RF image noise via an initial calibration step that involves the control of the relative amplitudes and phases of electrical driving modulation waveforms, while a second calibration step involves the differential suppression of photoacoustic artefact signals via tuning, in the optical domain, of the relative intensity the optical beams that are delivered to the sample. Another example embodiment involves the use of the standard deviation of the unwrapped phase that is obtained, after performing frequency-domain cross-correlation and an inverse transform to the time domain, to improve the amplitude signal that is employed to generate a differential photoacoustic radar image.
