摘要： Methods and systems for converting text into natural personal handwriting are provided. One aspect relates to the training of a computer to recognize a user's handwriting style. In one embodiment, the computer receives handwriting samples of at least one character written by the user, such as the character being provided as the beginning, middle, or ending character among a plurality of other characters. Further embodiments allow for increased personalization of the handwriting. Another aspect relates to system and methods for displaying a representation of a computer user's handwriting. In one embodiment, the handwriting comprises variant shapes of letters, personalized connection style between letters, and connection parts that look pressure-sensitive. In another embodiment, characters are adjusted, such as cutting portions of the character to create a more realistic recreation and synthesis of the handwriting.

摘要： Systems and methods for perceptual image preview are described. In one aspect, a naïve preview image is generated by downsampling a larger image. Perceptual features of the larger image are then detected. Information associated with the detected perceptual features is then incorporated into the naïve preview image to create a perceptual preview image. Since the perceptual preview image incorporates information associated with the detected perceptual features, a viewer of the perceptual preview image will be more likely to detect the presence or absence of such perceptual features in the larger image.

摘要： Methods and systems for training a computer to recognize and verify an individual's signature are provided. One illustrative method extracts a plurality of both global and local features from a relatively small sample of handwriting samples. In one such embodiment, only 5 samples are needed from an individual without requiring forgeries. In yet another embodiment, only three global parameters are utilized, thus reducing the complexity, and processing power, of the system. Utilizing such few global parameters also facilitates fine tuning of the systems. Further aspects of the invention relate to a multi-stage statistical system for on-line signature verification. In one embodiment, the system may comprise a simplified GMM model built on global signature properties and a left-to-right HMM model based on segmental features. In one embodiment, specific strategies are utilized to create model simplification and initialization in contrast to general GMM and HMM models.

摘要： Disclosed are a concrete distributing device and a control method, a control system and an electrical control system for composite motion of a boom thereof. The control method comprises the steps as follows: calculating the flow of a boom pump when an operating handle sends a command; according to the command sent by the operating handle, calculating theoretical demand flow of all actuating mechanisms of the boom and theoretical control signals of all electronic proportional control valves; comparing the total theoretical demand flow of the actuating mechanisms with the flow of the boom pump; providing the theoretical control signals to all the electronic pro portional control valves when the flow of the boom pump is greater than or equal to the total theoretical demand flow of the actuating mechanisms, otherwise, providing actual control signals smaller than the theoretical control signals to all the electronic proportional control valves and reducing the movement speeds of all the actuating mechanisms proportionally. In this way, when undersaturation of system occurs to the composite motion of the boom, the movement speeds of all the actuating mechanisms are reduced proportionally independent of the load difference of the actuating mechanisms, thereby ensuring that the boom can move in a motion track expected by an operator.
