    摘要： A method and apparatus analyzes a scene to determine which pupils correspond to which subjects. First, a machine-readable representation of the scene, such as a camera image, is generated. Although more detail may be provided, this representation minimally depicts certain visually perceivable characteristics of multiple pupil candidates corresponding to multiple subjects in the scene. A machine such as a computer then examines various features of the pupil candidates. The features under analysis include (1) visually perceivable characteristics of the pupil candidates at one given time (“spatial cues”), and (2) changes in visually perceivable characteristics of the pupil candidates over a sampling period (“temporal cues”). The spatial and temporal cues may be used to identify associated pupil pairs. Some exemplary spatial cues include interocular distance, shape, height, and color of potentially paired pupils. In addition to features of the pupils themselves, spatial cues may also include nearby facial features such as presence of a nose/mouth/eyebrows in predetermined relationship to potentially paired pupils, a similarly colored iris surrounding each of two pupils, skin of similar color nearby, etc. Some exemplary temporal cues include motion or blinking of paired pupils together, etc. With the foregoing examination, each pupil candidate can be associated with a subject in the scene.

    摘要： A computationally efficient, machine-implementable method and means for detecting and correcting errors in received codewords on-the-fly within the capacity of a linear cyclic code using ultra-fast error location processing. Each error locator polynomial of degree t over a finite Galois field derived from a codeword syndrome is mapped into a matrix representative of a system of linear simultaneous equations related to the polynomial coefficients. Roots indicative of error locations within the codeword are extracted from the matrix by a modified Gaussian Elimination process for all the roots where t.ltoreq.5 and at least one root plus a subset of candidate roots from the finite field for iterative substitution where t>5. Corrected values are separately determined and correction is secured by logically combining the corrected values with the codeword values in error at the error locations represented by the roots.

    摘要： A high dimensional indexing method is disclosed which takes a set of objects that can be viewed as N-dimensional data vectors and builds an index which treats the objects like k-dimensional points. The method first defines and applies a set of feature extraction functions that admit some similarity measure for each of the stored objects in the database. The feature vector is then transformed in a manner such that the similarity measure is preserved and that the information of the feature vector v is concentrated in only a few coefficients. The entries of the feature vectors are truncated such that the entries which contribute little on the average to the information of the transformed vectors are removed. An index based on the truncated feature vectors is subsequently built using a point access method (PAM). A preliminary similarity search can then be conducted on the set of truncated transformed vectors using the previously created index to retrieve the qualifying records. A second search on the previously retrieved set of vectors is used to eliminate the false positives and to get the results of the desired similarity search.

    摘要： A method for managing a usage cost of an asset. A user component of a business entity may access the asset after the asset has been developed by a development component of the business entity, wherein the user component receives compensation from a compensator in response to the user component having incurred a usage burden from using the asset, and wherein the compensator may have contributed to the usage burden. Alternatively, a user component of a second business entity may access an asset after the asset is developed by a development component of a first business entity, wherein second business entity receives compensation from the first business entity in response to the user component having incurred a usage burden from using the asset. The compensation has a magnitude that is a function of the usage burden. The asset may be a software application.

    摘要： A system and method for eye gaze tracking without calibrated cameras, direct measurements of specific users' eye geometries, or requiring the user to visually track a cursor traversing a known trajectory. The preferred embodiment includes two uncalibrated cameras imaging the user's eye and haying on-axis lighting. The cameras capture images of a test pattern in real space as reflected from the user's cornea, which is essentially a convex spherical mirror. The invention then extracts parameters required to define a mathematical mapping between real space and image space, including spherical and perspective transformations. The invention processes subsequent images of objects reflected from the user's eye through the inverse of the mathematical mapping to determine a gaze vector and a point of regard. Alternately, a single calibrated camera may be employed with means for estimating the eye-to-camera distance. A head-mounted embodiment that may include a laser pointer is also described.
