Application: Systems and methods for determining and using a multidimensional measure of apparent skin color (Patent ID: US20230419549A1)
The patent by Sony Group Corp. describes systems and methods for computing a multidimensional score of apparent skin color to capture skin color variation and address biases related to skin color in image datasets and computer vision models. The method involves segmenting skin pixels, extracting lightness and hue values, clustering the pixels, computing histograms, and assigning scalar values based on the mode of the histogram. By focusing on perceptual lightness and hue angle, the method aims to provide a more representative assessment of skin color effects in computer vision, enhancing diversity in data collection and identifying biases in fairness benchmarking.
Furthermore, the patent details methods for determining bias in face image datasets and computer vision-based models by analyzing apparent skin color. This involves calculating scalar values for lightness and hue, determining bias in datasets based on skin tone and hue, and assessing biases in machine learning models. The method also includes generating images to evaluate bias presence, using generative adversarial networks and diffusion models. By applying these techniques, the patent aims to improve the identification of biases related to skin color in datasets and models, ultimately enhancing fairness and accuracy in computer vision applications.
