    Deals with a neural network method for the machine recognition of mixed facial expressions by decomposing mixed facial expression into 2 or 3 components of 6 basic ones. The authors obtain the facial images, which show mixed facial expressions, from video tape recorded facial images and from the information of facial expressions in terms of the (x,y) coordinates of facial characteristic points.

    This paper introduces an application of photometric stereo to facial feature measurements. First, the authors propose a modified photometric stereo which reduces the size of the table and errors of the table lookup. Then, three applications are described, all of which use the gradient data obtained by the modified photometric stereo. These examples show that the photometric stereo is quite suffici...

    A method of describing human movements in a symbolic manner is discussed. Human workers learn operation skills by repeating the task. It is not easy for the worker to describe his skill as robot commands or motion control parameters. To transfer human skills to robots, they must be represented in a symbolic form. In this analysis, the human operator's movements are converted into a sequence of tri... View full abstract»

    The electromyographic (EMG) signal from active muscle is observed on the surface of the living body, and considered for controlling an externally powered upper extremity prosthesis. However, the EMG signal depends on physical condition, the state of mind and so on. So it is difficult that the original EMG signal could be used as a command for controlling an externally powered upper extremity prost... View full abstract»

    In image recognition, simple neural networks often recognize incorrectly due to the effect of changes in size and shifts in position of the object in the source image. The neocognitron is effective to recognize the image; however the network scale is too large, so it takes a long time to train the network and to process the information. The authors propose a car detection system using the simple m... View full abstract»
