Weak hypothesis generation apparatus and method, learning apparatus and method, detection apparatus and method, facial expression learning apparatus and method, facial expression recognition apparatus and method, and robot apparatus

A facial expression recognition system that uses a face detection apparatus realizing efficient learning and high-speed detection processing based on ensemble learning when detecting an area representing a detection target and that is robust against shifts of face position included in images and capable of highly accurate expression recognition, and a learning method for the system, are provided. When learning data to be used by the face detection apparatus by Adaboost, processing to select high-performance weak hypotheses from all weak hypotheses, then generate new weak hypotheses from these high-performance weak hypotheses on the basis of statistical characteristics, and select one weak hypothesis having the highest discrimination performance from these weak hypotheses, is repeated to sequentially generate a weak hypothesis, and a final hypothesis is thus acquired. In detection, using an abort threshold value that has been learned in advance, whether provided data can be obviously judged as a non-face is determined every time one weak hypothesis outputs the result of discrimination. If it can be judged so, processing is aborted. A predetermined Gabor filter is selected from the detected face image by an Adaboost technique, and a support vector for only a feature quantity extracted by the selected filter is learned, thus performing expression recognition.

Voltage/current testing equipment for microfluidic devices

The present invention provides novel methods and devices for testing / verifying the configuration of one or more microfluidic elements in a microfluidic device. In particular the methods and devices of the invention are useful in testing for blockages or the presence of air bubbles in microfluidic elements. For example, a method for verifying the proper function of a microfluidic device is disclosed, which device comprises at least first, second and third fluidic openings, which fluidic openings are fluidly coupled to at least first, second and third microscale channel elements, respectively, the method comprising flowing an electrically conductive buffer through the first, second and third microscale channel elements; setting a known applied voltage potential (or current) between the first and second fluidic openings; setting a current in the third microscale channel element to be approximately zero; detecting a resulting voltage at the third fluidic opening; and, comparing the detected voltage at the third fluidic opening with a calculated target voltage expected at the third fluidic opening to determine whether there is a fault or problem (e.g., air bubble) in at least one of the first and second microscale channel elements. The above method can be repeated one or more times for the other fluidic openings in the microfluidic device to determine whether there is a fault in any one or more microscale elements of the device.
