It was the aim of this study to improve tissue characterization using ultrasonic scatter signals and image processing procedures by computer. Analysis of various tissue probes and phantoms showed that structures can be differentiated by scatter as a

Using 20 MHz ultrasound the different layers of human skin tissue can be separated. This process of pattern recognition is done by extracting features within a twostep process including an autoregressive signal model with a weighting factor for the e

A method for absolute measurement of flow quantities by excitation of a slice orthogonal to the measuring plane is presented. The developing flow profile can be imaged directly and its dynamic behaviour can be sampled and measured using the multiecho

If the input signals of the visual system in the cat are statistical patterns in space and time, a complete system analysis can be carried out. What counts here as a system are the neuronal networks between retina and recording site. In the case of l

The objective of the paper is to determine in abstract terms the algorithms used by the cat detecting simple patterns and to quantify the contributions of the visual areas 17, 18, 19 for this task. The data incorporated in the algorithm are collected

In the first part of this paper some phenomena in the nervous system are described, concerning the time interval structure of the nervous signals. The characteristics of the neurons are introduced and interpreted. It is shown theoretically and proved

Quantitative behavioral experiments have shown that the toad uses mainly two types of gestalt information in prey/enemy discrimination: pattern extension in the direction of movement promotes, in general, the signal value prey, while extension perpen

Recent interest in neural networks is largely triggered by the idea that knowledge from this field may be advantageously applied to problems arising in massively parallel computing. Besides increasing processing velocity, parallelism provides possibi
