Chen Lu actually joined this game as a forensic doctor?
It seems surprising at first glance, but when you think about it, it’s not surprising at all.
Everyone is new to the dark level, and they were promoted just last month. The first round of the dark level competition is only two days apart, so there is a chance that we will be ranked together.
And although the experience is quite different, this game limits everything, which greatly smoothes out the messy elements. Being put into the same hero pool is nothing.
Chen Lu was not embarrassed to be lined up with her former students.
After all, the two of them had already started collaborating on the head transplant surgery.
Moreover, I have seen the genius Chen Kou before. I met such a person when I was a doctor.
He was so handsome that he often said: "Only crooked people talk about appearance..." The surgery was also a mess, as if it was a charade.
Being assigned to Ye Han, she was eager to try: she could finally see with her own eyes how this genius competed!
Although there will definitely be recording and broadcasting in the village, how can watching the recording and broadcasting be as exciting as the Taiwanese one?
Without saying any nonsense, he brought a stool, then another stool, and handed Ye Han the equipment while watching this guy's operation without blinking.
I’ve done it once, and it’s much faster if I do it again.
It only lasts about eighty or ninety minutes.
Looking at the interference fringes on the display screen, Chen Lu fell into confusion.
Although her intelligence is not very high, she is a doctor after all, and she is an absolute science major. She still has a certain understanding of double-slit interference, direct radiation fringes, diffraction fringes, and even stripes that can dance when disturbed by will. She has also heard of it, but...
There was a mosaic on the screen, with stripes that looked like a Go board. She had never seen it or heard it before.
Ye Han was actually just as confused.
Mosaic stripes?
Photon polarization has a direction. If it hits a polarizer and diffracts in a limited direction, it is possible, but...
The only person who is not at a loss is [(?_?)]
【Are you dumbfounded? Are you confused? 】
[Small sample, my palace’s Tangtang system still can’t cure you?]
"..."
Even Ye Han, who has an EQ of 39, understands that the mosaic is not interference stripes, but created by the system.
It is mentioned in the rules of the arena that the system cannot act casually unless a player destroys the field and sees that the game cannot accommodate it, such as in the last round, or there is a major bug.
This is obviously not the case right now.
Therefore, this mosaic is not specifically designed to block oneself, but is set like this for this round of the game.
Then there's no way……
"What should we do next?" Chen Lu was not as careless as Ye Han. After thinking about it, she understood what was going on.
Seeing Ye Han's silence, she suddenly realized: "Don't worry, I won't team up with you. You do your mission, I'm just curious..."
Ye Han shook his head, he didn't mean that at all: "It doesn't matter if they are together. Well, have you heard of Rossmer's formula and Bayesian inference?"
I have never heard of the former, but of the latter... I have heard of Bayes' theorem. I remember it was in the first chapter of undergraduate probability theory. What is Bayesian inference?
==========
Three departments of investigation, large office room.
The ringing phone sounds continued one after another.
The police officers were still coming in and out, busy with their feet in the air.
"Sergeant, I know a formula that can be used to determine where the victim was last seen, where the body was found, and the severity of the crime..."
Ye Han got straight to the point and approached the red-necked police sergeant.
As soon as I started to speak, someone suddenly hugged my neck: "Hey, where is your kid? He's so lazy that I spent a long time looking for him."
The unique sense of rhythm of black people, accompanied by strong body odor... Needless to say, he is Ye Han's new partner.
"Chris, I still have..."
He still had something to say, but he never had the chance to say it.
Although after training, he has reached a strength of 83 and can squat 200 kilograms. He is no longer the weakling he used to be. But in front of the talented black guy, he is of no use. He was dragged away and forced to his desk.
side.
"I know, man, newcomers all want to show up, think about solving crimes, and want to get promoted and get a raise to become a police sergeant. But, man, that's not the case, no! no! no! no!" rap rhymes like that, That girl
So rhythmic.
"You have to learn to accept it, mature slowly, start small, and then..."
Can I solve a big case in three days by starting small? Ye Han glared at Chris, and Chris stared back without giving an inch.
Staring at each other with black guys is almost like people from Northeast China staring at each other: What are you looking at? What are you looking at? Try looking at me again? I just looked at you...
"Pfft..." Chen Lu couldn't help but laugh.
The situation in front of him was obviously not within Ye Han's plan.
Chris was startled: "Oh mom, is there someone else here?"
Having studied abroad for many years, Ye Han has rich experience in dealing with white people and black people.
Although he did not summarize it, he verified the experience summarized by others with the experimental group, control group, control group, and matching group, and he could always find something suitable.
For example, with white people, you have to be more direct, and with black people, you have to convince them.
How to convince this guy...
Ye Han's eyes wandered and fixed on Chris's computer screen. There was a blurry black and white photo on it. It was really blurry, not even a mosaic.
"What is this?" Ye Han asked.
"The photos of the missing boy from Jinshui Street were captured by surveillance cameras. Unfortunately, they were too blurry..." Chris looked back at the computer screen. "The people in the technical department said it would take at least 24 hours to deal with it clearly."
"24 hours? This is not that difficult, right? The enhancement of this kind of grayscale (that is, black and white) image is easier than the full-color image... It is nothing more than using total variation to minimize the Euler-Lagrangian partial differential equation
Transformation acts on total variation functionals..."
With these words, the black man and Ji Xu were stunned. Ye Han took the opportunity to push Chris away and sat down by himself.
Search maple, nothing...
Searched MATLAB again, still nothing...
Mathematica, of course not!
In addition to the three major mathematics software, PS does have it, but... that thing is the icing on the cake. It is also commonly used when splicing electron microscope images. Can you use it to solve crimes? Are you kidding me?
(#`O′)
Although the minimization of Euler-Lagrangian partial differential equations is a calculus technology developed long before the birth of computers, without program assistance, how can it be done by hand?
Well...if you think about it carefully, it's not impossible.
The so-called grayscale digital image is nothing more than a function in a given rectangular space simplified to a function F(x,y) in the real number unit interval [0,1].
=0, it is white; =1, it is black; other cases are represented by grayscale between black and white.
So this picture is nothing more than 1200×720 data that needs to be processed.
It seems like a lot, and the classification has its own rules. Of course it is tricky to calculate by hand, but computer assistance does not require a whole set of software. It only needs to establish a set of simple logical mappings, fill in the data here, automatically generate the results there, and then put it back together.
Digital images will do.
Thinking of Ye Han, he immediately took action, well... As expected, there is no programming software.
