We present a method of improving sound source separation using vision. The sound source separation is an essential function to accomplish auditory scene understanding by separating stream of sounds generated from multiple sound sources. By separating a stream of sounds, recognition process, such as speech recognition, can simply work on a single stream, not(More)
In this paper, we report an initial design of humanoid head platform for RoboCup humanoid challenge. While many research in RoboCup humanoid challenge naturally focus on walking and running behaviors, we focus on perception and high-level behavior issues using an upper-torso humanoid. We have designed an head/neck part of the humanoid with aesthetic design,(More)
In this paper, we present a method of integrating auditory and visual perception for mobile robot for RoboCup. When humanoid robots are fielded for soccer game, they need to quickly react to the environment using all possible sensory inputs. While current robots heavily depends on visual inputs, auditory inputs actually play significant role in detecting(More)
A 9-month-old girl developed subacute limited adduction of the left eye, presenting with blepharoptosis. An orbital magnetic resonance imaging (MRI) 2 months after the onset revealed swelling of the left lateral rectus muscle, with increased intensity on T2-weighted images with fat saturation, which was enhanced with gadolinium. She was diagnosed with(More)
