    Piano fingering is one of the important skills for piano performance, especially for beginners. Consequently, technology for recognizing a player's fingering is required in order to develop an automated piano lesson system. The term “piano fingering” refers to which fingers are used for pressing piano keys. In this paper, we propose a method for recognizing piano fingering by analyzi... View full abstract»

    This paper proposes a novel framework to calibrate cameras and model a scene simultaneously using both self-calibration constraints and geometric information on parallelograms. The proposed method is a factorization-based approach solving the problem by decomposing a measurement matrix into camera and parallelogram parameters. Since the factorization-based approach recovers all camera poses simult... View full abstract»

    The process of finding traversable ground is important to autonomous vehicles. To achieve this, 3D maps that contain the information about vehicle's surroundings are generally used. One of the simple methods to represent 3D maps is to use 3D point clouds collected by range sensors. But, it requires lots of memory and computation time to deal with point clouds. To solve these problems, we propose a... View full abstract»

    Template matching is the basic technique of the image processing for the object detection such as OCR(Optical Character Recognition), Face detection, and the defect inspection. The template matching can detect the XY displacement and the rotational angle of the target object from the input image captured by the camera. We have proposed the eigen template method for the template matching problem. E... View full abstract»

    This study assesses how people interpret human ages based on images of faces. We assigned the age of the people imagining how old they are as the “subjective age” and proposed an experiment to identify its mechanism. The participants in the experiment were presented with the facial images of other people and asked to estimate the ages of those in the images as either younger or older... View full abstract»
