Latest Patents

Among Yang's notable inventions is the patent for a **3D-HEVC depth video information hiding method based on single-depth intra mode**. This invention introduces a sophisticated approach to embedding information within depth video streams. The method involves an information embedment segment and an information extraction component. When pixel values in a candidate list are identical, encrypted information is used to modulate pixel indices to facilitate information embedding. Conversely, if pixel values differ, the method adapts by analyzing neighboring Coding Units (CUs) to optimize information embedment while maintaining security and efficiency. This innovation is characterized by its high security, low computational complexity, and minimal impact on data rate.

Another of Yang’s recent patents is the **method for evaluating quality of tone-mapping image based on exposure analysis**. This method enhances the assessment of high dynamic range images by categorizing them into three distinct sections: areas prone to overexposure, underexposure, and natural exposure. By analyzing exposure properties within these areas, the method allows for the extraction of relevant quality characteristics. This ensures that the evaluation of quality degradation is both accurate and targeted, taking into account various factors such as the abnormal exposure rate and residual energy metrics.
