OUTLINES OF A THEORY OF AUTOMATIC data MANAGEMENT IN A pattern recognition ENVIRONMENT.

1975年 222-227页

作者： Page, Carl V.

Criteria which facilitate the design of an automatic data manager for a large data base are proposed. A syntactic pattern definition language provides a set of subdefinitions which can be preprocessed. A total expected cost graph for a pattern definition set is used to define preprocessed sets for various costs. The problem of the design of preprocessor or automatic data manager is related to the specification of an appropriate adaptive system.

DUAL ISOTOPE IMAGING: AUTOMATED LIVER-PANCREAS SUBTRACTION.

引用

1975年 65-67页

作者： Gose, Earl E. Shponka, Samuel Barnes, W.Earl Kaplan, Ervin

Automated techniques are presented for discrimination between two organs on the basis of their differential uptake of two radioactive substances. Their feasibility is tested on images of the liver and pancreas.

ASSOCIATION MECHANISM BASED ON CODING THEORY AND ITS APPLICATION TO pattern recognition.

引用

1975年 196-200页

作者： Ichikawa, Tadao

This association mechanism enables a simple hardware building of recognizers by saving the large scale computations normally required for pattern recognition. recognition rates are remarkably improved by the flexibility of adapting to the repeated appearances of particular patterns to be recognized, and this is also closely related to the association capability. Experimental results are given for the case of on-line recognition of handprinting.

TRANSITION NETWORK GRAMMARS FOR SYNTACTIC pattern recognition.

引用

1975年 139-146页

作者： Chou, S.M. Fu, K.S.

Transition Networks (TN) have been proposed by Woods models for language analysis. It has been found that transition networks grammars are powerful and practical to model natural languages. It achieves some of the objectives of a transformational grammar, which represents a sentence structure in terms of surface and deep structures. In addition, it is efficient in representation and parsing and is flexible for expanding experiments.

STORAGE VS. ERROR TRADEOFFS IN pattern recognition AND CLASSIFICATION.

引用

1975年 339-342页

作者： Pearl, Judea

This paper establishes absolute bounds on the amount of memory required to perform pattern-recognition tasks with a misclassification rate not exceeding a specified level. pattern-recognition activities are viewed as communication channels with sample sets as inputs and decision rules as outputs. Shannon's rate-distortion theory gives rise to language-independent bounds on the complexity of class descriptions as a function of the number of samples, the size of the data space and the error level tolerated.

SYSTEM DESIGN ISSUES IN PROSODIC RULE IMPLEMENTATION.

引用

1975年 204-207页

作者： O'Malley, Michael H.

Acoustic prosodic information about syntactic boundaries was incorporated into two different types of speech understanding systems. This paper presents a brief outline of English prosodies and then reports the effect on system performance of using prosodic information. Issues of overall system design which effect the implementation of prosodic rules are discussed.

RESOLUTION PRESERVING TEXTURAL TRANSFORM FOR IMAGES.

引用

1975年 51-61页

作者： Haralick, R.M.

This paper describes an image dependent two-dimensional nonlinear spatial filter designed to be a resolution preserving textural feature extractor for image data. The textural transform is based on the neighboring grey tone co-occurrence properties of the image to be transformed. Classification experiments with the textural transform on satellite multispectral scanner imagery over forrested areas show that higher identification accuracy can be achieved when using combined spectral and textural information than when using only spectral information.

ELECTROCARDIOGRAM INTERPRETATION USING A STOCHASTIC FINITE-STATE MODEL.

引用

1975年 316-322页

作者： Albus, John

This paper describes the basis of a syntactic approach to the problem of electrocardiographic rhythm interpretation. The general use of syntactic methods for pattern recognition has been described by K. S. Fu. The problem of interpreting an output sequences of a stochastic finite-state automaton M is defined to be the problem of finding the sequence of states w for which p(w vertical a,w//0) is maximum, where w//0 is the initial state of M. A tree search solution to this problem is described. The application of this method to certain types of analog signals is discussed.

METHOD FOR MAXIMUM LIKELIHOOD PARAMETER ESTIMATION BASED UPON A REDUCED data FILE.

引用

1975年 249-252页

作者： Tarter, Michael E.

procedures are considered which can supply a variety of maximum likelihood estimators from a reduced data setUnlike method involving the use of grouped data, this new approach is based upon new model-free, e. g. , nonparametric, estimation techniques and consequently is well suited for pattern recognition applications. An example is given of a class of estimators which contains the sample mean and sample median.

TEXT, INPUT, graphics and data structURES.

引用

1975年 31-37页

作者： Rhodes, Michael L.

This paper describes a cooperative interaction between human recognition and descriptive powers and a text understanding program for generating facial images. data structures for program control, data management and image modification are illustrated. The discussion includes implementation techniques used in developing the interactive program. Relation ambiguities encountered by the program are resolved by interrogating short term memory buffers and hash table data. Language and hardware features are combined by a data structure that interfaces display processor instructions and requests generated by the interpreted text. Updating this structure is discussed in terms of relationships between structure elements.
