Disclosed is a method for assigning the content of a digital image to a class of a classification system. Said method comprises the following steps: &#x2014;a predetermined number of F numerical shape characteristics &#x3c8;are determined; &#x2014;the value of each shape characteristic of the F numerical shape characteristics determined for the image is compared to the value filed in a table for the respective shape characteristic, values for the individual numerical shape characteristics being allocated to each class in the table; &#x2014;the class in which the F numerical shape characteristics determined for said image correspond best to the values of the numerical shape characteristics indicated in the table for said class is output as the class into which the image that is to be recognized is classified.

Method for associating a digital image with a class of a classification system

To reduce signal interference and improve the signal-to-noise ratio in the transmitted signal, the analog signals produced by an ultrasound transducer are promptly digitized. In accordance with the invention, the demodulator is already shielded from the ultrasound transducers, immediately after the preamplifier, which is itself shielded from the ultrasound transducers, by an analog to digital converter, for example.
