Latest Patents

One of Sijia Wen's latest patents is an "Image defogging method based on simulated polarization foggy scene data set." This method involves obtaining a polarized fog-free scene image set and generating a first quintuple based on each image. The process includes extracting pixel coordinates from significant polarization images to create a second quintuple, which is then used to generate a simulated polarization foggy scene data set. The method employs a polarization state attention neural network to improve the accuracy of image defogging, even in poor lighting conditions.

Another significant patent is the "Method for calculating image highlight reflection separation based on polarization guidance." This method utilizes a polarized color sensor to capture polarized color images and calculates a polarized chromaticity image. By clustering pixels of diffuse reflection components and applying a robust principal component analysis algorithm, the method achieves highlight reflection separation without being affected by lighting information. This results in a more accurate highlight reflection separation through the use of color and polarization data.
