Chen Kun, who was frowning, was slightly startled when he heard Lu Chuan's voice.

Chen Kun has his own method for image enhancement, and after so many years of verification, it shows that this method is very effective.

This is why Chen Kun doesn't like to use software that everyone uses. He uses a very niche portrait processing software.

When Chen Kun was young, someone taught him how to do it.

Later, Chen Kun became the technical expert who firmly held the top spot in the Pictorial Investigation Team, and no one said anything about it.

Moreover, Chen Kun has confidence in himself. If he can't handle the images in the entire Haizhou City, it will be useless for others to come.

However, Lu Chuan's reminder was like an enlightenment, and Chen Kun, who was stuck at the bottleneck, suddenly opened his mind.

I don't care why Lu Chuan, a person who conducts spot surveys and identifies fingerprints, knows about Fourier transform.

Chen Kun subconsciously asked, "You mean to use Fourier transform to convert the image into a digital image?"

Lu Chuan nodded: "Now the image noise and sharpening processing have been relatively successful. The only flaw is that the original photo has low pixels."

"It may be better to use Fourier transform to convert the photo into a digital image, and then enhance the data to improve the pixels of the photo from the bottom layer of the data."

"From the bottom of the data... enhance the pixels?"

Chen Kun murmured a few words.

Snapped!

After pondering for a moment, Chen Kun slapped his thigh and shouted excitedly: "Why didn't I think of that?"

After saying that, Chen Kun immediately started data processing on the photos.

However, the following work also confirmed Chen Kun's words, there are specialties in the art industry.

Half an hour later.

The image is still the same as before.

It's not like the girls in some action movies, who can still make emotional expressions even if they don't feel anything.

It's not done, it's just not done, there's no surprise at all.

"This Fourier transform... is not easy."

As an expert in image processing, Chen Kun is of course quite clear about using mathematically transformed images for data conversion.

But knowing means knowing, but just because you know many things doesn’t mean you know how.

"Teacher Chen, maybe the software you are using has some problems with data conversion. How about I give it a try?"

Lu Chuan watched from behind for half an hour, and he had already noticed that Chen Kun's skills in digital image transformation were not particularly high.

Especially the software used by Chen Kun, although it can also perform data processing, is in fool mode and is far less useful than the program written by Lu Chuan himself.

When Chen Kun heard that Lu Chuan wanted to try it, he quickly stood up.

Chen Kun knew that Lu Chuan had a background in fingerprinting, but just heard that he could propose using Fourier transform to convert images and then perform data enhancement, which shows that he has made achievements in this area.

Lu Chuan was not polite either, and the two exchanged positions.

Chen Kun stood behind Lu Chuan, and Lu Chuan sat in front of the computer.

For image processing, Lu Chuan actually separated some skills from the skills of advanced fingerprint identification analysis.

Although when processing fingerprints, some processing of sharpening and denoising fingerprint images is also required.

But fingerprint pictures are linear and the pictures themselves are relatively simple.

So the skill level requirement in this area is not high.

Lu Chuan mostly performs mathematical transformations on fingerprint images, and then enhances the data to achieve the purpose of making blurred images clear.

The structure of portrait images is more complex, requiring more time and operations in terms of denoising and sharpening.

Fortunately, Chen Kun had already completed these tasks in the previous processing. Lu Chuan only needed to mathematically transform the image and then enhance the underlying data.

After downloading his commonly used software, Lu Chuan imported the software he had compiled from the USB flash drive.

Then Chen Kun will be

Drag the sorted image in and start data conversion.

In the past, Lu Chuan's data conversion of fingerprint images was relatively simple. He only needed to convert each ridge, and then the entire image was completed.

However, there are only twenty or thirty ridges on a fingerprint image at most.

The amount of converted data is smaller, but the portraits are different.

It is not simply composed of twenty or thirty lines. The amount of data that needs to be processed for a portrait may be the amount of data of hundreds of fingerprint images.

Although the principles are the same, this is also the reason why Lu Chuan always crashes in his office using his own computer.

As expected, the computer of the Scouting Brigade lived up to Lu Chuan's expectations.

The amount of data that once crashed his own computer runs very smoothly on the computer Chen Kun uses.

The data strips of data conversion are advancing at a speed visible to the naked eye.

From the looks of it, it can probably be done in about ten minutes.

"Wait a moment, data conversion will take some time."

"Haha, don't be in a hurry."

Wu Kaiyue also saw it.

No wonder, Liu Guodong just called and said he wanted to borrow a computer instead of borrowing a person.

This Lu Chuan is not only great at fingerprints, he is also great at image enhancement.

Wu Kaiyue could understand most of what Lu Chuan had done on the computer just now, but there were still some operations that he couldn't understand.

What does this mean?

This shows that Lu Chuan's ability in image processing is superior to his own.

"Is this a program you compiled yourself?"

Chen Kun asked in surprise.

Image processing is not as simple as addition and subtraction. What is the concept of being able to compile a program by yourself?

At least, Chen Kun himself does not have this ability.

"Actually, it's just a plug-in program. It mainly relies on the software itself, and then having a computer with better performance is basically enough."

"Teacher Chen, I put this small plug-in program on the computer desktop. If you don't mind it, you can also study it. This plug-in program cooperates with this software to process images into data, and it has some better effects."

Lu Chuan felt that he was a systematic person and could be appropriately generous.

What's more, I'm borrowing someone else's computer this time.

"Ah...oh, thank you."

"Also, don't call me teacher. I'm a few years older than you. If you don't mind, just call me Brother Chen."

At the beginning, Chen Kun had no objection to Lu Chuan calling him Teacher Chen.

Chen Kun feels that he does still have some strength in image processing. Although Lu Chuan is good at fingerprint processing, as he said, he has a specialization in the field.

However, it now seems that the other party is not weak in image processing.

Although image data conversion is only one aspect of image enhancement, Chen Kun feels that Lu Chuan is better than him in this aspect.

"Okay, Brother Chen."

As he spoke, the progress bar reached 100%.

The image data conversion is completed.

Of course, data transformation is only the first step, and the rest is the most critical, which is to enhance the underlying data.

This cannot be solved by a small plug-in.

This requires experience and requires more mathematical transformations.
