 or more face sub-images of one or more faces in the image; a characteristic point detector, for receiving input from the face detector to be use for estimating one or more characteristic facial features as characteristic points in each detected face sub-image; a facial feature detector, for detecting one or more contours of one or more facial components; a facial feature analyzer, capable of determining a mouth shape of a mouth from the contour of the mouth and creating a representation of the mouth shape, the mouth being one of the facial components; and a face classification unit, for classifying the representation into one of a neutral class and a non-neutral class. It is noted that the face classification unit can be a neural network classifier or a nearest neighbor classifier. Moreover, a face recognition method disclosed in U.S. Pub. No. 2005102246, in which first faces in an image are detected by AdaBoost algorithm, and then face features of the detected faces are identified by the use of Gabor filter so that the identified face features are fed to a classifier employing support vector machine to be used for facial expression recognition. It is known that most of the emotion recognition studies in Taiwan are focused in the filed of face detection, such as those disclosed in TW Pat. No. 505892 and 420939. As is well known in the art, gas turbine engines are started by rotation of their compressors to provide sufficient pressurized air to support combustion of fuel in burners of the engines. In a typical gas turbine engine starting sequence, a starter first rotates the compressor at a constantly increasing speed. Next, when rotation of the compressor has established adequate air flow through the engine, a fuel ignition system is turned on, and then fuel flows into the burners and is ignited by the ignition system. At this stage of the starting sequence, the force generated by the fuel combustion is inadequate to permit the engine to accelerate to a self-sustaining, or self-accelerating speed. Consequently, the starter must continue contributing torque to assist the engine in achieving a self-sustaining speed. After the engine accelerates beyond its self-sustaining speed and approaches its idle speed, the ignition system and the starter are cut out, and the engine continues on to its idle speed.
To achieve the shortest possible total starting time, or "optimal start time", the starter remains engaged for the longest possible time. That is because, after combustion of the fuel commences, the engine and starter are working together to furnish the torque necessary for engine
or more face sub - images of one or more faces in the prototype; a characteristic item detector, for receiving input from the face detector to be consumption for estimating one or more characteristic facial features as characteristic decimal point in each detected face bomber - image; a facial feature detector, for detect one or more contours of one or more facial components; a facial feature analyzer, capable of settle a mouth shape of a mouth from the contour of the mouth and make a representation of the mouth shape, the sass being one of the facial components; and a face classification unit, for classify the representation into one of a neutral class and a non - neutral class. It is note that the face classification unit can be a neural network classifier or a nearest neighbor classifier. Moreover, a face recognition method disclosed in U.S. Pub. No. 2005102246, in which first faces in an image are detected by AdaBoost algorithm, and then face features of the detect grimace are identified by the manipulation of Gabor filter so that the identify face features are fed to a classifier employing documentation vector machine to be used for facial expression recognition. It is know that most of the emotion recognition studies in Taiwan are focused in the filed of face detection, such as those disclose in TW Pat. No. 505892 and 420939. As is well known in the art, gas turbine locomotive are started by rotation of their compressor to leave sufficient pressurized air to support combustion of fuel in burner of the engines. In a typical gas turbine locomotive starting succession, a starter first rotates the compressor at a constantly increasing speed. Next, when rotation of the compressor has established adequate atmosphere flow through the engine, a fuel ignition arrangement is turned on, and then fuel flow into the burners and is ignite by the ignition system. At this stagecoach of the starting sequence, the effect generated by the fuel burning is inadequate to permit the engine to accelerate to a self - sustaining, or self - accelerate speed. Consequently, the starter must continue contributing torque to help the engine in achieving a self - prolong speed. After the engine accelerates beyond its self - sustaining speed and approaches its dead speed, the ignition system and the starter are cut out, and the engine continues on to its baseless focal ratio. 
 To achieve the shortest potential full starting time, or " optimal start time ", the newcomer remains engaged for the longest potential time. That is because, after burning of the fuel commences, the engine and starter are working together to furnish the torque necessary for engine
