Abstract

The invention relates to automation, high technology and can be used to create systems for automatic analysis of graphic information, namely, to determine the area and perimeter of the image of the figures. The aim of the invention is to expand the functionality by determining the area of the figure. This goal is achieved by the fact that a device containing a single-channel switch, a clock generator, a photodetector array, a counter, an additional three-channel switch, three three-bit shift registers, an additional counter, a two-input AND element, and an eight-input I-HE element are added. 1 il. with (L

The purpose of the invention is to expand the registers 1, 7 and 7 are connected

the counter 5 and the second counter 6, three. Along with this, analyze the state of the three-digit shift register: the first 25 points surrounding the selected one, opvy 7 (, second 7, j and third 7; it is determined whether the selected the fine point is NOT-8, with the outputs being registered on the contour of the image or inside

7, with the exception of the second output of the contour. If the point does not belong

Since register 7 is connected to the input circuit of the image, then all the surrounding element AND 9, the first output of which its points must also have a second-order signal value connected to the second output. In this service register 7, the control input at the output of the NAND element of the first counter 5, the output of the element of the Yets is the desired signal level, which

9 is connected to the control input; it is blocked by adding a counting

pogo counter 6, the outputs of the three-channel-35 units in the second counter. If vybgo switch 3 is connected to a corresponding-wound point on the contour with other consecutive inputs, then at least one of the surrounding

shift registers 7 ,, 7 and 7 ,, clock-points corresponds to the zero signal inputs of which are connected to the output. cash on one of the register outputs

generator of 4 clock pulses, -40 7,, 7, and 7h. At the same time, at the output of the Unit, the device operates as a C ° operating at level 8, a high level and contents

at once, counter 6 is increased by 1, When

survey of photodetectors corresponding to With the help of switches 2 and 3 points that do not belong to the shift registers 7 ,, 72 and 7j of the recording-45 image, the second output registers the signals in turn, corresponding to 7 wringing the three upper points of the extreme. leads to blocking of the first upright vertical tire. Thus, the 5 and the second counter 6 are processed by means of the 2nd and 3rd element switches I. As a result, the shift registers 7, 1 and 7, after gg 6, at the end of the survey of the whole matrix are filled in with fragments of all receivers 1 a code is written, the ratios consisting of the central-appropriate number of points of the image point and its surrounding points, when it lies only on the contour of the image, than the second output of the second register of the figure, i.e. The perimeter of the image shifts repeats the state of all to-gg rage figures, and in counter 5, the code, check. arrays of photodetectors 1. while ska corresponds to the number of all the tonings of the last one in rows, the figure of the figure of the figure, in columns. To provide such a re-thus functionalities. press three-channel switch 3 the device has expanded its capabilities

by simultaneously calculating the perimeter and area of the figure. In addition, using such a device, it is possible to calculate the length of a straight segment. The accuracy of the calculation is increased by calculating not the number of light-shadow, and shadow-light transitions, but the number of points belonging to the image contour.

The time of calculating the area and perimeter of any complex shape is equal to the time of polling all photodetectors of the matrix, the functionality of such a device can be easily expanded due to the possibility of processing images according to the methods and principles of picture logic, i.e. processing 9 image points simultaneously. So, for example, it is easy to implement the execution of any linear filtering operation with the help of three shift registers and additional elements that learn the weights of points in the image.
