Latest Patents

One of Heng's latest patents is titled "Robust machine learning for imperfect labeled image segmentation." This invention aims to improve the performance and accuracy of image segmentation neural networks. It features a cascaded robust learning framework that includes two stages: a sample selection stage and a joint optimization stage with label correction. In the first stage, clean annotated samples are selected for network updating, which helps eliminate the influence of noisy samples. The second stage involves a label correction module that works alongside the joint optimization scheme to revise imperfect labels. This ensures that the training of the entire network is supervised by both corrected and original labels.

Another notable patent is the "Binocular visual experience enrichment system." This invention employs binocular tone mapping within a computer-based graphics imaging system. It utilizes an optimization-based framework to generate a binocular single vision image that offers more visual richness than a single tone-mapped image. The binocular tone mapping is guided by a binocular viewing comfort predictor (BVCP) metric, ensuring stable formation of binocularly tone-mapped image pairs. This approach maximizes the visual information content of the image pair while minimizing visual discomfort.
