Chapter 620 Botanists

meeting room.

The crabapple flowers on the window sill were pink, and the cigarette butts in the pot were carefully picked up by a botanist, and the smell was pleasant.

The meeting room is very empty, only the broken pen can't write, and the sound of flicking the pen anxiously.

Huang Qiangmin urgently mobilized a batch of fountain pens to solve this problem.

The botanists then went about their business in silence.

For Su Lei and others, botany itself is a dull science that does not require much language communication, and most of the knowledge is accumulated over the years.

This made her doubt Jiang Yuan's botany ability.In terms of age alone, students of Jiang Yuan's age are at most postgraduates and have just started their doctoral studies. The reason for this consideration is that undergraduates and masters are logically too late to reserve enough botany knowledge of.

Not every botanist can recognize all the plants in an arboretum, and many may not recognize most of them.However, recognizing all the plants in the botanical garden is far from being a botanist.

With Su Lei's way of thinking, she could easily think that if Jiang Yuan didn't have the real ability of forensic botany, wouldn't there be a huge problem with the botanical evidence identified by his hands.

Thinking of this, Su Lei's sense of social responsibility instantly exploded.

And Su Lei's scientist spirit made her focus on the job she just received.

She believes that the conclusion of her work is the best explanation!

The video crawled out by the drone was divided into grid-by-grid pictures. Su Lei zoomed in and looked at them one by one. If she encountered any doubts, she would mark them out, and then go back to read them carefully. It felt quite comfortable.

After writing down two steps in the notebook, Su Lei asked the familiar botanist next to her, and said, "Who processed this image? It feels similar to satellite remote sensing images. The image enhancement is quite good."

Satellite remote sensing images are the so-called only way to be applied. Only after image correction, image enhancement, and information extraction are performed on the obtained images, manual interpretation will be carried out.

Although the image area that Jiang Yuan and others faced was not as large as that of satellite remote sensing images, it was still too difficult to distinguish with the naked eye, and there must be a lot of rework.The current model is obviously much more advanced, and the accuracy and convenience have also been improved.

The botanist who came first was also obviously very satisfied. He smiled and murmured, and said, "The image enhancement done by Team Jiang is said to be for video surveillance and the like, and he is self-taught."

"This..." Su Lei couldn't hold back on the spot: "At the same time, teach yourself video surveillance, image enhancement, and learn botany at the same time?"

"Hmm..." The botanist who came first obviously didn't think this kind of thing was normal, but he didn't have the strength to refute.

Su Lei blinked, looked around involuntarily, and said, "There are five botanists among us, none of whom seem to understand satellite remote sensing image processing."

"Because we are botanists!" The one next to him emphasized.

"But forensic medicine will process satellite remote sensing images. Is this normal?" Su Lei looked at the pictures assigned to her computer. Among other things, the geometric correction was done very beautifully.Modern botanists are almost always exposed to satellite images, including those taken by drones, because of the deformation of photographic materials, distortion of the objective lens, and atmospheric refraction...the original images do not have real alignment.

As for their correction...to put it simply, it is much more difficult than using Photoshop to beautify people.

In addition, the captured images cannot always be clear, and contrast adjustment, color composition, density segmentation, and image fusion are all essential.

Finally, even image cropping is the work of image preprocessing.

Su Lei has seen images that were processed very comfortably, and images that were made uncomfortable. Now that she thinks about it, she feels that the image in front of her is something she has been in contact with, and the processing is one of the best.

The botanists in the same room have more seniority than Su Lei, and they have seen many more pictures.At this time, Su Lei heard about this topic, and they praised Jiang Yuan one after another.

Jiang Yuan said modestly: "Our forensic studies are inherently complicated. There are special branches of forensic imaging and forensic botany, but they are relatively shallow, so please bear with us."

"Don't dare to go too deep. If you go deeper, those who are engaged in satellite remote sensing and botany will lose their jobs." The botanist next to him shook his head.

"No, we are all the kind of people who are just scratching their heads, so we need everyone's help." Jiang Yuan said, clicked on the print on the computer, and the inkjet printer next to him began to work creakingly.

Su Lei couldn't sit still, she stood up again, stepped on her high heels, and came to the printer in a hurry.

It is a large commercial printer with a fixed asset identification card on it, with "Jianjiang City, Shannan Province" written in large characters.

Su Lei frowned, feeling a bit out of harmony, but didn't notice any specific problems.

"Is there something wrong with this col?" The picture Su Lei saw was enlarged and marked.She took a closer look and found that there was nothing wrong with the labeling. The vegetation in this area did look like a corpse, and she judged: "The new shrubs look like four or five years old, and they should not be six years old."

"Well, dig it out and see if there's something wrapped in it." Jiang Yuan also walked over, standing a head taller than Su Lei.

Using forensic botany, it is generally possible to judge the burial situation within a few years, and the corpses that usually do not use coffins and other methods will be more obvious.Therefore, if it is wrapped with straw mats or plastic sheets, the underground environment or state will be different, and forensic doctors are not very clear about how it is different.

The concept of corpse farms has existed for a long time, and there are not so many corpses in China and abroad that are such a disaster.

If other majors are faced with the shortage of research funds and researchers, forensics is faced with the shortage of research materials, especially in recent years, those who engage in forensic research are almost on par with those who engage in alien research—— They began to use theory to surpass reality.

Su Lei looked up at Jiang Yuan.Speaking of which, Jiang Yuan is younger than the master students she leads, but what Jiang Yuan is saying and doing now, and even his current laxity, are beyond the reach of most botany scholars.

"Forensic Doctor Jiang seems to be doing it pretty quickly." Su Lei asked.

Jiang Yuan smiled and said: "I came earlier, for a while, when I finish, I can help everyone."

"That's good." Su Lei was polite, and went back to her seat to do things.

Later, a policeman from the special class for accumulated cases came over and took the printing paper from Jiang Yuan's hand. Someone organized a small team, including all members of the police dog squadron, to go to the local area to dig.

After a while, Jiang Yuan printed a few sheets of paper in a row, and then started to walk around.

Su Lei looked over unexpectedly, and asked, "Just for a while?"

"Well, I'll hand in the paper first. Is there anything I can help you with?" Jiang Yuanke asked politely.

The botanists who can be included in Pang Jidong's list and dare to accept the invitation are definitely the best in the domestic botanical field.Jiang Yuan's forensic botany is only a branch of the branch of botany, and there is nothing to be proud of.

Su Lei always felt incredible, recalling her previous thoughts, thoughtfully tested Jiang Yuan, and said: "I have a few questionable plots here, Team Jiang can help me take a look."

Jiang Yuan nodded, came over to take a look immediately, and quickly proposed a solution, saying: "I think there should be no problem, if you are worried, we can process the image again."

As he spoke, he returned to his seat, and with the output of Quack, the enhanced image was sent to Su Lei.

Su Lei looked at the extremely clear image and the land that had been excluded from suspicion, and couldn't help but fall into self-doubt.

A layman looking at Jiang Yuan will only think that this guy is very powerful, like the kind of expert who grew up from other people's children.

Only Su Lei is like this. She was originally a child of someone else's family. She was so good at studying. She skipped grades and took exams. She took the college entrance examination at the age of 14, and went abroad after graduating from a university at the age of 17. Five years later, she even finished her doctorate and entered the station on the spot. After returning to China two years later, it was Siqing who started. In less than five years, he had his own team. Then he chose a new direction and took his students. One of the preparatory leaders in the academic field.

It can be said that the other botanists present may be very strong in terms of strength and ability, but they are also older, and their resumes are more ordinary, at least in high-level academic circles, they cannot be called geniuses of.

Su Lei is a real genius in the academic world, and a genius with a full load. She thinks that among her peers, there may be someone who can surpass her achievements. After all, this thing also depends on luck, but it seems that she is only in her 20s. Jiang Yuan, who is still a forensic doctor, has a high level of botanical knowledge, which really challenges Su Lei's three views.

Coupled with a high level of image enhancement technology...

"Thank you. Can you make some more pictures for me?" Su Lei asked directly.

"Okay." Jiang Yuan agreed.His path has already been pierced, and now he is going to support other lines.

The image of the C-line is also relatively complicated, so Su Lei chose it on purpose.Although most of the images have been processed by Jiang Yuan and can be read smoothly, but Jiang Yuan had limited time before, and faced with a large number of pictures, he could only do rough processing.

The few pictures that Su Lei put forward were all plants with very complicated conditions and clear enough images.Although research and judgment can also be done, the efficiency and effect are definitely not very good.

Jiang Yuan didn't doubt that he was there, and he moved quickly after sitting down. The image processing technology of LV5 can only be said to be explosive in the face of the normal image taken by the drone.

After another moment, Su Lei got a new image.

Compared with the previous images, this set of images is not only clearer, but also obviously classifies the plants accordingly, that is, by using the prior knowledge of the category attributes in this area, the characteristics of these sample categories can be used to establish A certain discriminant function is established, thus the type of the whole image is divided.

Needless to say, such an image is friendly to botanists. Su Lei feels that this is more comfortable than the image she got from the national laboratory.The satellite remote sensing experts over there don't handle the pictures so thoughtfully.

Su Lei made an appraisal silently, and then silently threw the new image to Jiang Yuan.

Jiang Yuan continued to deal with it, still very fast.

The two went back and forth, which actually made the work progress a lot faster.

Gradually, Su Lei even felt a tinge of guilt towards Jiang Yuan: I actually neglected such a genius among geniuses because he is a forensic doctor. Isn't this just the unfair treatment I have received?Why did I suddenly become like this, it should not be...
