Chen Kun, who was frowning, was slightly stunned to hear Lu Chuan's voice.
Chen Kun had his own set of thods for image enhancent, and after many years of validation, it proved to be very effective.
This was also why Chen Kun didn't like using software that everyone else used; he used a very niche portrait processing software.
When Chen Kun was younger, soone had taught him how to do it.
Later, Chen Kun beca a technical expert in the Image Investigation Brigade, securing the top position, and no one said anything anymore.
Moreover, Chen Kun was confident that if there was an image he couldn't process in the entire Haizhou City, it would be useless for others to try.
However, Lu Chuan's reminder was like a sudden enlightennt, breaking open Chen Kun's bottleneck.
He didn't care why Lu Chuan, a person from a Cri Scene Investigation and fingerprint analysis background, knew about the Fourier transform.
Chen Kun instinctively asked, "You an using Fourier transform to perform image-to-data conversion?"
Lu Chuan nodded: "Now the noise and sharpening processing of the image have been relatively successful; the only flaw is that the original photo's resolution is relatively low."
"Using the Fourier transform on the photo for image-to-data conversion, then enhancing the data from the underlying level to improve the photo's resolution, might be better."
"Enhance resolution from the data layer...?"
Chen Kun murmured a couple of tis.
Clap!
After pondering for a mont, Chen Kun slapped his thigh excitedly and exclaid, "Why didn't I think of that?"
After saying this, Chen Kun imdiately started processing the photo's data.
However, the subsequent work proved Chen Kun's earlier statent, that each profession has its specialization.
Half an hour later.
The image was still the sa as before.
Unlike so action movie bellas, who can make expressive faces, even if they feel nothing.
If it isn't done, it isn't done; there's no unexpected outco at all.
"This Fourier transform... is not easy."
As an expert in image processing, Chen Kun was certainly clear about using mathematical transformations for image data conversion.
But being clear is one thing, knowing is another, many things you know don't an you can do them.
"Teacher Chen, it might be the software you're using has so issues with data conversion. How about I give it a try?"
Lu Chuan had been watching for half an hour, and he had long realized that Chen Kun wasn't particularly advanced in number-to-image transformation technology.
Especially the software Chen Kun was using, though capable of data processing, was in a beginner's mode, far less effective than the program Lu Chuan himself compiled.
Hearing that Lu Chuan wanted to try, Chen Kun imdiately got up.
Chen Kun knew that Lu Chuan was from a fingerprint background, but just heard him suggest using the Fourier transform for image conversion and data enhancent, which showed he had achievents in this area.
Lu Chuan didn't stand on ceremony and the two swapped places.
Chen Kun stood behind Lu Chuan, and Lu Chuan sat in front of the computer.
Regarding image processing, Lu Chuan actually branched out so skills from advanced fingerprint analysis.
Although when handling fingerprints, it also requires sharpening and denoising the fingerprint images.
But fingerprint images are linear, and the images themselves are relatively simple.
Therefore, the skill level required isn't very high in this area.
Lu Chuan mainly used mathematical transformations on fingerprint images, then enhanced the data to make blurry images clear.
Portrait images are more complex to construct and require more ti and operations for denoising and sharpening.
Fortunately, Chen Kun had already completed these tasks in the previous processing, and Lu Chuan only needed to perform mathematical transformations on the image and then enhance the underlying data.
He downloaded his commonly used software and imported his already compiled program from a USB drive into the software.
Then he dragged the image processed by Chen Kun into it and began the data conversion.
In the past, when Lu Chuan did data conversion for fingerprint images, it was relatively simple, needing only to convert each ridge line, and then the whole image was done.
However, a fingerprint image's ridge lines are at most twenty or thirty.
The amount of data converted is small, but portraits are different.
Portraits are not composed of a simple twenty or thirty lines; handling a single portrait's data could be equivalent to hundreds of fingerprint images' data.
Although the principles are the sa, that's also why Lu Chuan's computer in his office kept crashing when processing.
And true to Lu Chuan's expectations, the computer in the Image Investigation Brigade didn't disappoint.
The data volu that once crashed his computer operated very smoothly on the computer that Chen Kun used.
The data conversion progressed at a speed visible to the naked eye.
Looking at it, it could probably be finished in about ten minutes.
"Just wait a bit; data conversion takes so ti."
"Haha, no rush, no rush."
Wu Kaiyue also noticed it.
No wonder Liu Guodong just called to ask to borrow the computer rather than the person.
This Lu Chuan is not only great at handling fingerprints but also excellent in image enhancent.
Earlier, Lu Chuan's operations on the computer were mostly understandable to Wu Kaiyue, but so actions were obscure.
What does this say?
This shows that Lu Chuan's ability in image processing surpasses his own.
"Did you compile this program yourself?"
Chen Kun asked in surprise.
Image processing is not as simple as addition and subtraction; what does it an to compile a program yourself?
At least, Chen Kun himself didn't have this ability.
"Actually, it's just a small plug-in. Mainly relying on the software itself, and having a better-performing computer basically suffices."
"Teacher Chen, I've placed the small plug-in on the desktop. If you're interested, you might want to study it a bit. This plug-in works well with the software for image data processing."
Lu Chuan, feeling assured with his system, decided to be a bit generous.
Moreover, he was borrowing soone else's computer this ti.
"Ah... oh, thank you."
"Also, don't call Teacher. I'm a few years older than you; if you don't mind, just call Brother Chen."
Initially, Chen Kun didn't object to Lu Chuan calling him Teacher Chen.
Chen Kun felt he indeed had so capabilities in image processing, and while Lu Chuan was good in fingerprint handling, as he said, each field has its specialization.
However, it turns out the other party was not weak in image processing.
Although image data conversion is only one aspect of image enhancent, in this aspect, Chen Kun felt Lu Chuan was stronger.
"Okay, Brother Chen."
As they spoke, the progress bar reached one hundred percent.
The image data conversion was done.
Of course, data conversion is just the first step; the most critical part is the underlying data enhancent.
This isn't sothing a small plug-in can solve.
This requires experience and more mathematical transformations.
