Latest Patents

One of Jinwei Gu's latest patents focuses on radiometric calibration from a single image. This innovative method allows for the calibration of an image capture device, such as a digital camera, using either a color or grayscale image. The process involves identifying and analyzing edge pixels that correspond to transitions between different colors or grayscale levels in a scene. By analyzing the intensity distributions from the single image, an inverse response function for the image capture device is determined. For color images, this calibration calculates a function that maps blended colors of edge pixels to linear distributions. In the case of grayscale images, it derives a function that transforms non-uniform histograms of measured intensities into uniform distributions of calibrated intensities.
