  • Publication number: 20210206382
    Abstract: A configuration is realized that inputs terminal-acquired information of a mobile terminal in a vehicle to a learning model, estimates a driver's driving behavior, and performs processes such as calculating a score on the basis of an estimation result and giving a notice. Terminal-acquired information such as acceleration information acquired by the mobile terminal in the vehicle is input, and a process of estimating a driving behavior of the driver of the vehicle is performed. A driving behavior estimate of the driver and estimation reliability of the driving behavior estimate are calculated on the basis of the terminal-acquired information by applying a learning model.

  • Patent number: 9700264
    Abstract: The present invention is directed to a new joint estimation framework employing MAP estimation based on pixel-based latent variables for tissue types. The method combines the geometrical information described by latent MRF, statistical relation between tissue types and P-C coefficients, and Poisson noise models of PCD data, and makes possible the continuous Baysian estimation from detected photon counts. The proposed method has better accuracy and RMSE than the method using FBP and thresholding. The joint estimation framework has the potential to further improve the accuracy by introducing more information about tissues in human body, e.g., the location, size, and number of tissues, or limited variation of neighboring tissues, which will be easily formulated by pixel-based latent variables.
