Lu Yi doesn't have time to care whether the teacher is back or not now, because all his attention is on the information in his mind!

Lu Yi's feeling is right, this technical information is really the image processing and restoration technology he urgently needs now!

Of course, image processing and restoration is a complex project, not that there is this technical information, the previous learning of those technologies, will also be used, but this one, is the key technology of the whole project, the name of this technology is - "image intelligent simulation restoration technology"!

Although this name is still the first time Lu Yi has heard it, there is an "image restoration technology" that sounds similar to it, Lu Yi learned it in a professional class, and it is mainly proposed for the "degradation" in the imaging process!

The phenomenon of "degradation" in the imaging process mainly refers to the fact that the imaging system is affected by various factors, such as the defocusing of the imaging system, the relative movement between the equipment and the object, or the inherent defects of the equipment, resulting in the quality of the image not meeting the ideal requirements!

The image restoration technology that Lu Yi learned in his professional class is to use the prior knowledge of the degradation process to remove the blurred part of the image through the deblurring function!

It sounds very simple, but in order to restore the image, we must first make a proper estimate of the whole process of image degradation, and then establish an approximate mathematical model of degradation, and then we need to continuously revise the model, and after the correction, the distortion behavior in the degradation process is compensated to ensure that the image obtained after restoration is as close to the original image as possible!

However, the "image intelligent simulation restoration technology" that Lu Yi is going to learn now is different from what he learned in professional classes.

It directly puts aside the impact of "degradation", starts from the root of the image, looks for "clues" and "traces" on the image, and then cooperates with the database to use advanced intelligent algorithms to repair the defects at the specified position of the image!

However, due to the huge amount of data required, Lu Yi wants to perfectly repair the entire image without a large database to work with, which is still a bit unrealistic!

Fortunately, Lu Yi doesn't need to fix the whole image, only the exposed taillights are repaired, and with the data searched on the Internet, it should be no problem!

Database Acquisition

"Intelligent Image Recognition"

……

"Image Augmented Reality Simulation"

Database Analysis

……

The more he studied deeply, the more Lu Yi felt the power of this technology, and it was not until later that when he learned the technical information later, Lu Yi realized that this technology was just the tip of the iceberg of the magic system!

As for now, Lu Yi didn't have the heart to continue learning, and after confirming that he had learned all the key points of this technology, Lu Yi began to prepare for the restoration of that image!

The first is "database collection", because there is no large server to support, Lu Yi can only store the collected image data in the hard disk of the computer, fortunately he does not have much data to collect, that is, the rear view of various vehicles, and the image of various license plate numbers!

But even so, when Lu Yi used the network of the book center to basically collect the rear view of various models and various license plate images on the market, he found that the alien's own 1T large-capacity hard disk was almost full, and he had to stop wanting to continue collecting data, so he gave up!

Speaking of which, Lu Yi also has to admire the network speed here, it's really amazing, you must know that before the collection, the capacity of the hard disk is almost 500 G!

Although theoretically, the more data in the database, the better, but there is so much data in the network, even if Lu Yi keeps collecting 24 hours a day, it is estimated that he will not be able to collect it in a month!

After the data collection is completed, the next step is "image preprocessing", but this is not the technology on the data learned today, but what Lu Yi learned from the previous data!

Before we explain this technique, let's first understand a few things!

There are many people who think that the blurring operation is irreversible, that the blurred photo loses most of the valuable information, and that when the colors of each pixel are dispersed according to a certain radius, all the objects in the photo are mixed together, and what we see is a photo similar to a flat color painting!

In fact, this view is not entirely correct, because the information in the image is not lost, but redistributed according to certain rules, and this process is actually recoverable!

And "image pre-processing technology", we can also think of it as an advanced version of "image restoration technology"!

What Lu Yi has to do now is to use this advanced version of "image restoration technology" to first repair the blurred images on that photo due to out-of-focus, shaking, and artificially created images!

Like ordinary image restoration technology, the advanced version of image restoration technology, the same mathematical modeling, correction ,......, distortion compensation and other operations, if these projects are written in a variety of high-level languages, and then encapsulated, it is a basic instant kill on the market, a variety of image restoration software of the awesome product!

Although Lu Yi can also program, he doesn't have so much time to waste now, so he can only simply use technology to deal with it directly!

……

When Lu Yi was busy, in a classroom at the university, Lei Ming, a counselor majoring in visual communication at Level 11, was also scolding his mother with a black face, "Zhao Song, how did you become the dormitory director?"

Lu Yi is in the same dormitory as you, right?

Why didn't he come today?

It's not a small amount of courage, it's only the first day of his junior year, he dares to skip class, I don't think he wants to pass the course this semester......?

”

The squirrel was scolded and looked depressed, the guide had a hot temper, everyone usually didn't get along very well, and now they had to put their faces up for people to beat!

In order to escape his anger, the squirrel turned his mind and made an excuse for Lu Yi, "Hehe, instructor, Lu Yi didn't just have a car accident, I heard him say that he seems to have gone to the hospital for a review today ......!" ”

Lu Yi was in a car accident, of course Lei Ming knew that because of this incident, he was scolded by the vice dean, saying that he did not do a good job in the prevention and education of students' personal safety during the summer vacation!

Bah, this fucking summer vacation is over, and the students themselves have to run to the highway in the middle of the night to die, what's the blame Lao Tzu for?

But since Zhao Song said so, he couldn't pretend that he didn't hear it, "Then why didn't he ask for leave?"

Is it when I don't exist?

You ask him to come over tomorrow with the hospital checklist to show me ......! ”

……

After class, the squirrel waved his arms angrily, "You said that the eldest brother skipped class to go to the library to pick up girls, why should I be scolded by "landmines"?" ”

Landmine is the nickname they gave to the counselor, because it is a mine, and it will explode at the slightest click!!
