Description

I1

The invention relates to automation and computing, can be used in automatic image analyzers for counting the number of objects of complex configuration and is an improvement to the device by author. No. 1001127.

The aim of the invention is to expand the field of application of the device for counting images of objects with or without internal voids.

Figure 1 shows the block diagram of the device; figure 2 - functional diagram of the node encoder.

The device contains a matrix of 1 photodetectors, a block of 2 elements I, a block of 3 comparison elements, a block A of elements I, a pyramidal parallel adder 5, a block 6 of comparison elements, a block 7 of elements I, a pyramidal parallel adder 9, the first 9 and a second 10 parallel adders, unit 11 codes, the first 12 and second 13 channels of logical information processing, including blocks 6, 7, 8 and 3, 4, 5, respectively. The encoder 14 consists of the same nodes 15, each of which contains an OR 16 element and an AND 17 element .

The encoder 14 converts the input image into an image of objects without internal voids. The first channel 12 of the logical information processing calculates the sum of the total number of chords in the image, and the second channel 13 calculates the sum of the connected chords in the image. The number of objects is calculated by subtracting the sum of the associated chords from the sum of the total number of chords. The subtraction operation is performed by the first 9 and second 10 parallel adders. The first parallel adder 9 completes the binary code addition of the number of total chords with the inverse number of connected chords. The result of the first parallel adder 9 is summed with the unit produced by the unit 11 of the code in the second parallel adder 10. This is necessary for performing the subtraction operation in the additional code.

The device works as follows.

The binary image signals from the matrix 1 of the photodetectors in parallel enter the encoder 14, which is

Toit of homogeneous hg nodes 15 (figure 2). The signal at the forward output of node 15 is simultaneously an input to four adjacent nodes. It has a logic level of 1 if there is no signal from the corresponding element of the photodetector matrix 1, and there is at least one signal from the neighboring node 15 of the encoder 14. The inputs of the extreme nodes 15 that must be connected to the neighboring nodes are connected to the logical 1. At the beginning of the count the number of images of objects by the Reset signal (FIG. 2) is performed by the preparation of the encoder 14, i.e.

all nodes 15 take on the value of logical O. After the signal is dropped, the logical 1 is distributed from the edges of the matrix of nodes 15 of the encoder 14 to the external contours of the objects. The images of the objects along with the internal voids remain unfilled.

The transformed image from the inverse outputs of the matrix of nodes 15 of the encoder 14 is fed in parallel to the first channel 12 of the logical information processing: to the block 6 comparison elements and to the second input of the 7 elements I.

two adjacent elements in the row of the image matrix; the block of 6 reference elements outputs a signal at the beginning and end of the chord. In the case when the image starts from the left edge (matrix 1 of the photodetectors), to determine the beginning of the chord, the left extreme elements of the matrix are compared with zeros. The block of 7 elements And passes only a signal of the beginning of a chord. Thus, the input of the pyramidal parallel adder 8 receives the number of start signals of the chords. At its output, a binary code appears corresponding to the total number of chords.

The signals of the transformed image simultaneously arrive at the second channel 13 of logical information processing, specifically, at block 2 of elements I. At the output of block 2 of elements I, we get the total number of connected image elements included in the associated chords, which are

they are calculated in the same way as in the first channel. At the output of the pyramidal parallel adder 5, the inverse of the common code appears

Nodes g, d, e, g, h show the output signals of blocks 6, 7, 2, 3, 4, respectively,

The total number of chords at the output of the parallel adder is 8 C1 3, The total number of connected chords at the output of the parallel adder is 5 C2 2, the Number of objects is calculated by subtracting the sum of the connected chords from the sum of the total number of chords and is equal to one.

The invention can find application in automatic image analyzers, in particular for the analysis of biological, microstructural and other objects.
