St. N ° 951321 knows the device for ranking the frequency of the sampling codes, containing an impuser generator, a decoder, a group of AND elements, a group of OR elements, a delay element, an encoder, and a group of reversible pulse counters, with the input of the delay element connected to the output of the pulse generator, the outputs of the delay element are connected to the first inputs of the AND elements of the group, respectively, the input of the decoder is the information input of the device, the outputs of the decoder are connected to the first inputs of the elements of the OR group, respectively, the second input The ports of which are combined and connected to the output of the pulse generator, whose input is the control input of the device, the output of each element OR groups is connected to the input of the corresponding reversible pulse counter of the group, the output of each reversible pulse counter of the group is connected to the second input of the corresponding element AND group, the outputs of the elements AND of the group are connected to the inputs of the frame, respectively, the output of which is the output of the device, the direct and inverse control inputs of the reversible counters pulse The Grugosh is connected to the second and third control inputs of the device C1. A disadvantage of the known device is low productivity. This is due to the fact that in the ranked number of codes, the weight of the code in the sample is not specified, and, if necessary, weights must be determined manually. The aim of the invention is to improve the performance of the device. The goal is achieved by the fact that a reversible counter, an OR element, and a Bpok of AND elements are additionally introduced into the device for ranking sample codes, and the counting counter of the reversible counter is connected to the output of the pulse generator, the forward and inverse control inputs of the reversible counter are respectively connected with the third and second control inputs of the device, the output of the reversible counter is connected to the information input of the AND block, the control input of which is connected to the output of the OR element, the inputs are The OR elements are connected respectively to the outputs of the AND elements of the group, the output of the block of elements AND is supplied by the second information output of the device. The drawing shows a functional diagram of the proposed device. A device for ranking by frequency of the sampling codes contains information input 1, de-breaker 2, generator 3 pulses, group of elements OR 4, group of reversible counters 5, groove of elements AND 6, equalizer 7, information output 8, element 9 of delay, first control & l Key input 10, element OR 11, block 12 elements AND, reversible counter 13, second control input 14, second information output 15, third control input 16. When using the device in the system of statistical image analysis to highlight informative elements, The signal of which is displayed by the code value on the information input of the device, the latter operates in the following way. When preparing the device for operation, the reverse voltage counters 5 and 13 are zeroed, the control voltage is applied to the control input 14 (in this case, the counters 5 become summing, the counter 13 is output). The operation cycle of the device consists of two steps: accumulation and analysis of the sample; reading the result. The codes of the investigated feature (in the case of the image elements brightness) are received from the beginning of the device operation at its information input 1. Each code value corresponds to a pulse at the corresponding output of the desktop 2, which arrives at the first input of the corresponding element OR 4. At the same time, the pulse goes to the corresponding reversible counter 5, increasing the accumulated 1 frequency of this code. At the time of the end of the sample of codes, the sample is fixed (accumulated) in counters 5 and analyzed (sorted by code values). This completes the first step of the device operation cycle. To go to the second check, the control voltage is removed from input 14 and fed to input 16; herewith, counters 5 become subtractive), and counter 13 - summing. The reading of the result 31O begins with the supply of a ynpaensnoi signal to the input U, which triggers the generator of 3 pulses. The impulses from the generator's BI stroke come in the input of the delay element 9, to the second inputs of the OR elements 4 groups and to the counting input of the counter 13. In the counter 13, the pulses are summed, displaying at each moment the result of the average frequency of the accumulated frequency. The same impulses enter counters 5, reducing the frequencies accumulated in them. . At the outputs of the delay element 9, the pulses appear with a delay of each other} and the friend and arrive at the first inputs of the elements of the AND 6 groups. This is carried out by polling the state of the counters 5 in time. In the presence of a zero code in the counter 5, the pulse signal from the output of the corresponding element AND 6 of the group is fed to the corresponding hoppers of the encoder 7 and the element OR il. In this case, the output code 8 of the encoder 6 of the torus 7 appears the code of the magnitude of the test feature - (in this case, the brightness of the image elements), and the output 15 of the block of elements And 12 - the value of the corresponding sensitivity. The value of the code and the value of the corresponding frequency exist at outputs 8 and 15 simultaneously for the duration of one pulse. If necessary, rank the codes in order of kill. of their set frequency, the counters 5 are in the initial position 0 & 1 STILL, and the counter 13 is set to 1, After the accumulation step and the analysis of the sample are completed, the counters 5 remain summing, and the counter 13 - subtracting. The use of the proposed device allows for a better enhancement of the productivity compared with and where the weights are determined manually.
