Latest Patents

Etsuko's latest patents include a normal line information estimation device, a registered image group formation device, and an image collation device. The normal line information estimation device is designed to estimate normal line information of an object from its image. This device features an illumination direction estimation section that determines the illumination direction based on the image's luminance value. Additionally, it includes a normal line information estimation section that utilizes the illumination direction to estimate the normal line information. A specular reflection component estimation section is also part of the device, which estimates the specular reflection component from the normal line information and illumination direction. Furthermore, the normal line information estimation section can re-estimate the normal line information from an image after removing the specular reflection component.

Another notable patent is the parameter estimation method, which estimates parameters by calculating the maximum a posteriori probability for input data. This method employs an inner product for the input data, which is then replaced by a kernel function to facilitate parameter estimation. The process includes an offline operation for learning correlations between known parameters and their corresponding input data, as well as an online operation for estimating unknown parameters using the learned correlations.
