The invention relates to the field of information processing, in particular, to devices for recognizing graphical images, for counting and sorting signals in a pulsed form, and may find application in prediction and diagnostic systems, for example, in a medical diagnostic system. A device is known for analyzing and classifying images of an object containing an informative parameter sensor, such as chord lengths, connected to a controlled part divider and a logic unit, a switch whose outputs are connected to the control inputs of a controlled frequency divider, and an input to the corresponding logic output. block, and a code comparison circuit associated with the inputs of the registration channels. The purpose of the invention is to simplify the device for classifying images of objects. This is achieved by introducing a reversible counter into the device, one input of which is connected to the output of the controlled frequency divider, and outputs to the inputs of the code comparison circuit, a reverse control unit whose input is connected to the corresponding output of the logic unit, and output to another input of the reversible counter, with one of the outputs of the switch connected to the input of the comparison circuit, and the outputs of the registration channels to the inputs of the logic unit. The drawing shows a block diagram of a device for classifying images of objects. Sensor 1 of an informative parameter, for example, chord lengths, is connected to an adjustable divider 2 frequency pulses and, via a second input, a feedback circuit to logic unit 3. A television transmitting camera and a video pulse converter from an image to a number-pulse code can be used as a sensor. . Through switch 4, the logic unit is connected to a controlled divider 2 pulse frequency and to the code comparison circuit 5. In addition, through the reversal control unit, the logic unit 3 is connected to a reversible counter 7, the second input of which is connected to the output of a controlled frequency divider 652. The output of the reversible counter is connected to the input of the code comparison circuit 5. The results of the code comparison are fed to the registration channels 8-10 connected to the logic block. Consider the device for the case when, as an informative parameter that serves as the basis for the classification of objects, is the area of the image, measured at several levels of video signal discrimination. The device uses a chord length sensor. The device works as follows. Sensor 1 chord lengths create video pulses and convert the duration of video pulses chords from the classified image into a number-pulse code. 1-1 pulses from the output of the sensor are fed to a controlled divider 2 pulse frequency, the division ratio of which is changed by switch 4. The state of the switch is controlled by logic block 3. The logic unit, depending on the number of the measurement cycle carried out by the chord length sensor, sets the corresponding division factor controlled pulse frequency divider by setting the switch to the appropriate position, as well as using the control unit of the reverse, converts the reversible counter to the appropriate position (sum or subtraction). The set of pulses from the output of the chord length sensor, proportional to the area measured in this cycle, passed through the controlled divider 2, is counted in a reversible counter. After the specified number of measurement cycles has been completed, the switch sends a command to circuit 5, which compares the contents of the reversible counter 7, resulting from a series of consecutive summations and subtractions of the number of pulses passed through the controlled divider. A comparison is made with a certain set of codes (the number of codes determines the number of registration channels). If the number in the reversible counter exceeds the code being compared, a pulse is sent to the corresponding registration channel. Upon reaching a specific for each channel registration number in a logical

the block is given an appropriate pulse, at which the logic block generates a stop signal and the classification of the measured set of objects. The proposed scheme of the classifying device 5 was used to classify cytological preparations for normal and suspected malignancy.

As a chord length sensor, you can use a television measuring device that measures image areas at six levels of object video signal discrimination. The pulse of the discrimination level number 15 is fed to a switch that controls the division ratio of the controlled pulse frequency divider. When measured at the first level of discrimination, the first impulse determines the division factor, the second + - | , third -1, fourth + i, fifth -, sixth -fl. The + sign when the division ratio means that the reverse

the counter summarizes the pulses, the sign subtracts the pulses.

By measuring the total number of 100 cells and if the number of abnormal cells does not exceed seven, the device stops working and classifies the drug as normal by a signal from the total cell number counter. If the number of abnormal cells is more than seven, then by the counter signal of the number of abnormal cells, the device stops working and classifies the drug as suspicious.

The proposed device can be used not only for the classification of cytological preparations, but also in various systems for analyzing images of micro- and macroobjects. At the same time, its structure and communications do not change, only the division factors and the sequence of operations Addition and Subtraction of a reversible counter are changed, which is determined by the device operation algorithm.
