  • Pixel array and touch array crosstalk mitigation systems and methods
    Patent number: 11893185
    Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.
    Type: Grant

  • AUTOMATIC GATHERING STRATEGY FOR UNSUPERVISED SOURCE SEPARATION ALGORITHMS
    Publication number: 20100138010
    Abstract: Unsupervised learning algorithms for audio source separation such as non-negative matrix factorization (NMF) and principal components analysis (PCA) can be understood as a data matrix factorization subject to different constraints. These algorithms provide components with a relevant structure and homogeneous musical events. The invention presents an automatic fusion method to merge these components into tracks associated to the different instruments present in the sound source.
