Chapter 620: Botanists.

Conference room.

The crabapple flowers on the windowsill are pink, and the cigarette butts in the pot have been carefully picked up by a botanist, which smells pleasant.

The conference room is quiet, with only the sound of broken pens that can't write and the anxious sound of pens being thrown away.

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

The botanists continued to work silently.

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

This made her doubt Jiang Yuan's botanical ability. In terms of age alone, students of Jiang Yuan's age are at most graduate students and have just started doctoral studies. The reason for this consideration is that undergraduates and master's students should not have enough time to accumulate enough botanical knowledge.

Not every botanist can recognize all the plants in the botanical garden, and many people may not recognize most of them. However, recognizing all the plants in the botanical garden is still a long way from being a botanist.

With Su Lei's thinking, she could easily think that if Jiang Yuan did not have the real ability of forensic botany, then wouldn't the botanical evidence identified by him have great problems?

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

And Su Lei's spirit of scientists made her focus on the work she had just received.

She believed that the conclusion of her work was the best explanation!

The video from the drone was divided into grids of pictures. Su Lei enlarged 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, "Who processed this image? It feels similar to satellite remote sensing images. Image enhancement is also done quite well."

Satellite remote sensing images are the so-called necessary path for application. Only after the obtained images have been corrected, enhanced, and information extracted, will they be manually interpreted.

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

The botanist who came first was obviously very satisfied, and smiled and said, "Captain Jiang's image enhancement is said to be self-taught in video surveillance."

"This..." Su Lei couldn't hold it back on the spot: "Self-taught video surveillance, image enhancement, and botany at the same time?"

"Well..." The botanist who came first obviously didn't think this was normal, but he didn't have the energy to refute.

Su Lei blinked and looked around, saying, "There are five botanists in total, and it seems that none of them knows satellite remote sensing image processing."

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

"But forensic doctors know satellite remote sensing image processing, is this normal?" Su Lei looked at the pictures assigned to her computer. Apart from anything else, the geometric correction was done very beautifully. Almost all modern botanists have come into contact with satellite pictures, including the pictures taken by drones. Because of the deformation of photographic materials, distortion of objective lenses, atmospheric refraction... the original images are not really aligned.

And to correct them... to put it simply, it is always much more difficult than using Photoshop to beautify people.

In addition, the images taken cannot always be clear. Adjusting contrast, color synthesis, density segmentation, and image fusion are all essential.

Finally, even image cropping is also a work of image preprocessing.

Su Lei has seen images that are processed very comfortably, and also seen images that are processed very uncomfortably. Now that she recalls it, she actually feels that the image in front of her is one of the best she has ever seen.

Several botanists in the same room have more experience than Su Lei and have seen many more pictures. At this time, when Su Lei talked about this topic, they all gave Jiang Yuan a thumbs up.

Jiang Yuan said modestly: "What we forensic doctors learn is relatively complicated. There are specialized forensic imaging and branches of forensic botany. It's just that we learn relatively shallowly. Please bear with us."

"I dare not go too deep. If you go deeper, those who do satellite remote sensing and botany will be unemployed." The botanist next to him shook his head.

"No, we are the kind who only try a little, so we need everyone's help." Jiang Yuan said, and clicked the print button on the computer, and the inkjet printer next to him began to work.

Su Lei was a little impatient, so she stood up again, stepped on her high heels, and came to the printer.

It was a large commercial printer, with a fixed asset identification card on it, and the big words "Jianjiang City, Shannan Province" were shining.

Su Lei frowned, feeling a little uncomfortable, but did not notice any specific problems.

"Is there something wrong with this valley?" The picture Su Lei saw was enlarged and marked. She took a closer look and found that there was no problem with the marking. The vegetation in this area did look like there was a corpse, and she judged: "The new shrubs are about four or five years old, and should not be six years old."

"Well, dig it out and take a look, maybe it's wrapped in something." Jiang Yuan also came over, standing a head taller than Su Lei.

Using forensic botany, we can generally determine the burial situation within a few years. Moreover, corpses that are not usually buried in coffins will be more obvious. Therefore, if the body is wrapped in straw mats or plastic sheets, the underground environment or state will be different. The specific difference is not clear to forensic doctors.

The concept of corpse farms has long existed, and there are not so many corpses in China and abroad.

If other majors face a shortage of research funds and researchers, forensic doctors face a shortage of research materials, especially in recent years, forensic researchers are almost on par with alien researchers - they are beginning to use theory to surpass reality.

Su Lei looked up at Jiang Yuan. To be honest, Jiang Yuan is younger than the master's students she teaches, but what Jiang Yuan is talking about and doing now, and even his current relaxation, are beyond the reach of most botanical scholars.

"Forensic doctor Jiang seems to be doing it very quickly." Su Lei asked.

Jiang Yuan smiled and said, "I came earlier. I can help you guys when I'm done."

"That's great." Su Lei said politely and went back to her seat to work.

Later, a police officer from the special case team came over and took the printed paper from Jiang Yuan. Someone organized a small team and all the 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 and started to get up and walk.

Su Lei looked over in surprise and asked, "Really just a moment?"

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

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

Su Lei always felt incredible. Recalling her previous thoughts, she wanted to test Jiang Yuan and said, "I have a few suspicious plots here. Captain Jiang, please help me take a look."

Jiang Yuan nodded, came over to take a look, and quickly proposed a solution, saying, "I think it should be fine. If you are worried, we can process the image again."

He said and returned to his seat. With a clacking output, he sent the enhanced image to Su Lei.

Su Lei looked at the extremely clear image and the plots that were ruled out of suspicion, and couldn't help but fall into self-doubt.

Outsiders look at Jiang Yuan and only think that he is very powerful, like the kind of expert who grew up from someone else's child.

Only Su Lei is like this. She was originally a child of other people's families. She studied very hard and was very good. She skipped grades and took exams at the same time. She took the college entrance examination at the age of 14, and went abroad after graduating from undergraduate studies at the age of 17. Five years later, she even got a doctorate. She entered the station on the spot and returned to China two years later. She started with the Four Youths. In less than five years, she had her own team. Then she chose a new direction and led her students. She worked hard for seven years and was already one of the preparatory elders in the field of biology.

It can be said that the other botanists present may be very strong in strength and ability, but they are also old, and their resumes are ordinary. At least in the high-level academic world, they cannot be called geniuses.

Su Lei is a real genius in the academic world, and a genius who pulls up at full capacity. She believes that among her peers, there may be someone who surpasses her achievements. After all, this thing also depends on luck. However, seeing Jiang Yuan, who is only in his twenties and is still a forensic doctor, has mastered a high level of botanical knowledge, which really challenges Su Lei's three views.

Add a high-level image enhancement technology...

"Thank you. Can you help me make a few more images?" Su Lei asked directly.

"Okay." Jiang Yuan agreed. He had already broken through that line, and now he had to support other lines.

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

The few pictures Su Lei proposed were all very complex plant conditions, and the images were clear enough. Although they could also be used for analysis, the efficiency and effect were definitely not very good.

Jiang Yuan did not doubt him, and he sat down and moved quickly. The LV5 image processing technology, facing this kind of normal image taken by drones, can only be said to be a blast.

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 has corresponding classification of plants, that is, using the prior knowledge of the category attributes in this area, and then using the characteristics of these sample categories, a certain discriminant function can be established, thereby dividing the types of the entire image.

Such images are friendly to botanists, and Su Lei feels that this is more comfortable than the images she got from the national laboratory. The satellite remote sensing experts over there will not process the images so considerately.

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

Jiang Yuan continued to process it, still very fast.

The two of them cycled back and forth, which actually accelerated the progress of the work a lot.

Gradually, Su Lei even felt a little guilty towards Jiang Yuan: Such a genius among geniuses, I actually neglected him because he was a forensic doctor. Isn’t this the unfair treatment I once received? How did I suddenly become like this? It’s too wrong...
