摘要： An automatic monitoring and sensing apparatus is provided for detecting an intruder or a person whose presence is undesired for one reason or another. According to one aspect of the invention, a method and apparatus are provided for automatically monitoring an environment for the presence of a person, and the invention issues an alarm when the environment changes while the person is still present. For example, the invention is capable of detecting a person in an unexpected or dangerous location in the environment, such as a baby or small child who has been left alone in an automobile. The invention initiates remedial action to safeguard the person. In another aspect, the inventive method and apparatus automatically monitors an environment that is intended to be kept secure, such as an environment where a computer system is installed, wherein the apparatus initiates a safeguarding action such as a pre-emptive automatic back-up of data in the computer system.

摘要： A method, system and computer article are presented for smoothing an image calibration signal in order to smooth a reproduced signal, and to identify the presence of any remaining spikes or other significant deviations. The invention recognizes the problems with raw calibration signals, and posits that the calibration signals be filtered by methods and systems described. For example, calibration data may be smoothed by fitting the calibration data to a parametric model employing either linear or non-linear least squares. Alternate techniques implement smoothing using optimal filtering. An aspect of the invention is a method, computer product or article of manufacture for improving an initial calibration profile having an initial profile extent to form an improved calibration profile. The initial profile may be formed for a scanner employing a linear array CCD and having a particular direction of motion. One method includes forming an extended profile extent in the direction of motion using quadratic extrapolation, applying multirate filtering to the extended profile to form a filtered profile, and truncating the filtered profile to bring it to the initial profile extent to form the improved calibration profile.

摘要： Calibrated dither masks adaptable to most printers are constructed in such a way that the threshold values can be adapted to a printer so that said printer can print the originally intended number of distinct tone levels. This adaptation can be done computationally so that the time it takes is not prohibitive. Furthermore, the resulting calibrated dither mask is such that there is no need for a tone reproduction curve in the halftoning process.

摘要： Systems and methods for modeling functional magnetic resonance image datasets using a multivariate auto-regressive model which captures temporal dynamics in the data, and creates a reduced representation of the dataset representative of functional connectivity of voxels with respect to brain activity. Raw spatio-temporal data is processed using a multivariate auto-regressive model, wherein coefficients in the model with high weights are retained as indices that best describe the full spatio-temporal data. When there are a relatively small number of temporal samples of the data, sparse regression techniques are used to build the model. The model coefficients are used to perform data processing functions such as indexing, prediction, and classification.

摘要： The present invention provides a method for capturing and storing physiological response attributes measured from a user while different stimuli are presented. Each stimulus may be any multimedia object, for example text, picture, or audio/video. The measured physiological response attributes are paired with the input stimulus, and stored conjointly in one or more databases. The physiological response attributes measure an aspect of the user known as emotional valence, and relate to the emotional state of the user, such as angry or sad. The database of physiological responses attributes of multiple users is first established. Then, when the physiological response attributes of a specific user in the future is examined, the system can suggest which objects in the database best correspond. Moreover, the database can be constructed based on the responses of the individual user for their own utilization, and be updated over the course of its continued use.

摘要： The present invention provides methods and apparatus to distinguish and/or separate an object from a background. The methods use backgrounds of known and/or advantageous texture. In an embodiment, a measure of image texture, namely the spatial frequency is used to distinguish and/or separate an object from its background. The use of image texture overcomes limitations of chroma keying used as a processing technique in photography for object-background separation. This is useful in the separation of image pixels belonging to the object of interest from image pixels belonging to the background.

摘要： A semi-digital printer includes a print head assembly that prints an image on a sheet of paper that has been mounted onto a turntable, and a rotating means which rotates the turntable so that the print head assembly ejects ink or toner onto the sheet of paper at one or more predetermined angles. The printing may be halftone or color. If the print head assembly includes more than one print head, the rotating means rotates the turntable to a different angle for each print head. By rotating the turntable in this manner, the printer records an image at any angle (0° to 360°) precisely (i.e., without having to perform the angular approximations required by conventional digital printers). As a result, a printed image of improved quality is produced. Alternatively, the semi-digital printer may be configured so that the print head assembly rotates relative to the paper.
