using a channel value analysis device, connected to the butterworth low-pass filtering device, for receiving the low-pass filtered image, obtaining each red channel value of each pixel point of the low-pass filtered image, and performing the following operations for each pixel point of the low-pass filtered image: acquiring a red channel value of the pixel point as a channel value to be processed, acquiring each red channel value of each neighborhood pixel point of the pixel point, sequencing the red channel values of each neighborhood pixel point from small to large, taking the red channel value in the center of the serial number as a reference channel value, when the absolute value of the difference between the channel value to be processed and the reference channel value exceeds the limit, determining the pixel point as an edge pixel point, otherwise, determining the pixel point as a non-edge pixel point;
using a signal fitting device, connected to the channel value analysis device, for fitting each edge pixel point of the low-pass filtered image to obtain each region to be processed;
in the signal fitting device, fitting each edge pixel point of the low-pass filtered image to obtain each region to be processed includes: discarding the isolated edge pixel points in each edge pixel point of the low-pass filtering image to obtain each region to be processed.
10. The demographic-based data communication method of claim 9, further comprising:
using image enhancement equipment, connected with the signal fitting equipment, for performing image enhancement processing on each to-be-processed region in the low-pass filtered image, and reserving original values for image contents outside each to-be-processed region in the low-pass filtered image to obtain a pertinence enhanced image corresponding to the low-pass filtered image;
the image enhancement device is also respectively connected with the first identification device and the second identification device and used for respectively sending the targeted enhanced image to the first identification device and the second identification device in place of the real-time adjustment image;
using a DDR memory chip, connecting with the image enhancement device, and receiving and temporarily storing the low-pass filtered image and the pertinence enhanced image;
and the DDR memory chip is also connected with the signal fitting equipment and is used for temporarily storing each area to be processed.
