Latest Patents

One of Qifei Wang's latest patents is titled "Highly efficient model for video quality assessment." This invention outlines a method for generating reduced-quality streams from a video stream of a first spatial and temporal resolution. By sampling subsets of spatial-temporal points (STPs) from these streams, a machine learning model processes the STPs to identify quality scores. This allows for the identification of quality-improving actions for the video stream based on these scores.

Another notable patent is the "Multi-scale transformer for image analysis." This technology utilizes a patch-based multi-scale Transformer that is adaptable for various imaging applications. It effectively predicts quality on native resolution images by transforming them into a multi-scale representation. The self-attention mechanism captures information from both detailed and global patches, enhancing the overall image representation.
