  • Patent number: 10572978
    Abstract: A method for impulse noise detection and removal in color images based on Moran's I statistic using Moran's I vector median filter (MIVMF) which comprises detection and removal components. The detection module determines if a pixel is noise or is noise-free. If it is a noise pixel, the vector median filter (VMF) will be used to remove the noise. This detection capability meets the so-called “switching” mechanism, which only selects noisy pixels for suppression. The inventive filter expedites processing time with the reduced number of vector calculations due to this new detection function, achieved with Moran's I index and the indication of 1-D Laplacian kernels. Compared to other vector-type median filters, the inventive MIVMF was faster in the filtering process and efficient in removing random impulse noise with different noise levels in color images. The MIVMF demonstrated a promising de-noising result based on the criteria of Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index Metric (SSIM).

  • Patent number: 10397443
    Abstract: Systems, methods, and computer readable media are described for providing improved color remapping. In some examples, a video bitstream is obtained that includes a plurality of pictures having a first color characteristic. A color remapping information (CRI) supplemental enhancement information (SEI) message is identified from the video bitstream. A restriction is placed on the CRI SEI message such that a value of a syntax element of the CRI SEI message is restricted based on a condition. One or more samples of the plurality of pictures is remapped from the first color characteristic to a second color characteristic using a color remapping model of the CRI SEI message according to the restriction. In some cases, the condition is a chroma format of the plurality of pictures, in which case the value of the syntax element of the CRI SEI message is restricted based on the chroma format.
