Chen Lu actually entered this game, as a forensic doctor?

At first glance it may seem surprising, but when you think about it, it's not surprising.

Everyone is a newcomer to the dark level, and they were just promoted last month. In the first round of the dark level, there are only two days left to enter the time, and there is a chance that they will be lined up.

And although the experience is a lot worse, this game is limited to all, which greatly flattens out the messy elements, and being put into the same hero pool is nothing.

Lined up with former students, Chen Lu was not embarrassed.

After all, the two have already started working together on the head swap.

And the genius Chen Kou has seen it, and he met such a person when he was a doctor.

The handsome is miserable, and the forced words that often hang on the lips are: "Only serious people talk about appearance......" The operation is also a mess of the cow, like a hanging.

Separated from Ye Han, she was eager to try: she could finally see with her own eyes how this genius competed!

Although the village will definitely record and broadcast, how can it be cool to watch the recording and broadcasting?

Without saying a word of nonsense, he brought a stool, and then a stool, and while handing over the equipment to Ye Han, he watched this guy's operation without blinking.

Double-slit interference experiment, lighting, focusing, seam ......

I did it once, and it was much faster to come again.

It's only ten minutes.

Looking at the interference stripes on the display, Chen Lu fell into a daze.

Although her intelligence is not very high, after all, she is a doctor, an absolute science, and she still has a certain understanding of double-slit interference, direct shooting stripes, diffraction stripes, and even stripes that can dance when disturbed by the will, she has also heard of it, but ......

A screen mosaic, long like a Go chessboard-like stripes, she has never seen or heard of it.

Ye Han was actually at a loss.

Mosaic stripes?

Photon polarization has a direction, and if it is hit on a polarizer, it is possible to diffract in a limited direction, but ......

The only thing that is not at a loss is [ (?_?) 】

[Dumbfounded, huh? Confused, right? 】

[Sample, the palace system, can't cure you? ] 】

“……”

Even Ye Han's EQ 39 understands that mosaic is not interference stripes, it is made by the system.

As mentioned in the arena rules, the system can't shoot casually, unless a player destroys the field and sees that the game can't be accommodated, such as the last round, or there is a heavy **ug.

Apparently not at the moment.

So this mosaic will not be specifically blocked by itself, but this round of the game is set like this.

Then there is no way......

"What's next?" Chen Lu is not like Ye Han, who lacks heart, and after thinking about it, he understands what is going on.

Seeing that Ye Han was silent, she suddenly came to her senses: "Don't worry, I won't team up with you." You do your task, I'm just curious......"

Ye Han shook his head, he didn't mean that at all: "It's okay to be together." Well, have you ever heard of Rossmo's formula and Bayesian inference? ”

The former had never heard of it at all, and the latter ...... I've heard of Bayes' theorem, and I remember that in the first chapter of undergraduate probability theory, what is Bayesian inference?

==========

Three departments of investigation, large office room.

The ringing of the phone is still ringing.

The officers were still in and out, busy with their feet in the air.

"Policeman, I know a formula that can be used to ...... the severity of the crime by understanding where the victim last showed up, where the body was found, and how strong the crime was."

Ye Han went straight to the point and found the red-necked policeman.

As soon as he said half a sentence, he was suddenly hugged by the neck: "Hey, where are you kid?" It's going to be lazy, so I've been looking for it for a long time. ”

The unique sense of rhythm of black people, accompanied by a strong body odor...... Needless to say, it was Ye Han's new partner.

"Chris, I still have ......"

He had something to say, but he didn't have a chance to do so.

Although after exercise, he has a strength of 83 and a squat of 200 kilograms, he is no longer the weak chicken he used to be, but in front of the talented black buddy, it is useless, he was dragged away and forced on the side of his table.

"I know, buddy, newcomers are thinking about going out on the scene, thinking about solving cases, thinking about getting promoted and raising their salaries to become sheriffs. But, buddy, that's not the case, no! no！ no！ no！ "The rap rhymes, and that girl is so rhythmic.

"You have to learn to accept, mature slowly, start small, and ......"

Can I start small and solve a big case in three days? Ye Han glared at Chris, and Chris glared back without giving an inch.

and the black buddies stared at each other, almost like Northeast people staring at each other: What are you looking at? What do you see? Do you want to try again? I'll just see......

"Poof......" Chen Lu couldn't help laughing.

The situation in front of him was obviously not in Ye Han's plan.

Chris was taken aback: "Oh Mom, there's someone else here?" ”

After studying abroad for many years, Ye Han is experienced in dealing with whites and blacks.

Although it was not summarized by him, the experience summarized by others was confirmed by his experimental group, control group, control group, and matching group, and he could always find a suitable one.

For example, with white people, you have to be direct, and with black people, you have to convince them.

How do you convince this guy......

Ye Han's gaze wandered, fixed on Chris's computer screen. Above is a blurry black and white photo, really blurry, not to the mosaic is almost gone.

"What is this?" Ye Han asked.

"The photos of the disappearance of the boy on Jinshui Street, there are surveillance cameras that captured the picture at the time, but unfortunately it is too blurry......" Chris looked back at the computer screen, "The people in the technical department said that it will take at least 24 hours to deal with it clearly." ”

"24 hours? It's not that hard, is it? This grayscale (i.e., black and white) image enhancement is inherently easier than a panchromatic image...... It is nothing more than using the total difference to minimize the effect of the Euler-Lagrange partial differential equation on the total difference function......"

After a few words, he successfully stunned the black man and the murderer, Ye Han took the opportunity to push Chris away and sat down by himself.

Search for maple, no ......

I searched MATLAB again, and there was still no ......

Mathematica, of course, doesn't!

In addition to the three major math software, PS has it, but ...... That thing is the icing on the cake, and it is also commonly used when stitching electron microscope images, but you can point to it to solve the case? Are you kidding?

(#`O′)

Although the Euler-Lagrangian partial differential equation is minimized, it is a calculus technique developed long before the birth of computers.

Not...... If you think about it, it's not impossible.

The so-called grayscale digital image is nothing more than a function in a given rectangular space reduced to a function F(x,y) in the real number unit interval [0,1].

=0, it is white; =1, then black; Other cases are indicated in grayscale between black and white.

So this graph is nothing more than 1200×720 pieces of data that need to be processed.

It seems like a lot, and the classification has its own rules, and the manual calculation is of course tricky, but the computer-aided does not need a complete set of software, just establish a simple set of logical mappings, fill in the data here, automatically generate the results there, and then put back the digital image.

Thinking of Ye Han, he immediately started to act, huh...... Sure enough, there is no programming software.
