Diary of a Criminal Investigator-Chapter 254: Separating Fingerprints

Compiling a new software is not something that can be completed in a short time.

Of course, using grayscale values to layer-process images has a drawback, which is that the image’s color cannot be restored to color.

After processing, the images can only be gray.

Fortunately, in fingerprint identification analysis, color contrast has never been a comparison factor, so this influence is irrelevant.

In the Crime Scene Investigation office, Lu Chuan is compiling software, while Old Bai and Yang Sen are chatting about Yang Sen’s son’s college entrance exam.

"Less than two months left, right?"

"Fifty-three days."

Yang Sen sighed, "In fifty-three days, I’ll be completely free."

This sentence was spoken with what could be described as emotion.

Old Bai has been through it, although in the past it didn’t seem to matter much about the college entrance exam, it was definitely an unforgettable experience for life: "Have you thought about which university to apply to?"

"I took a casual look, but it actually depends on the scores. The scores in the recent mock exams are quite okay, basically able to get into a good school."

"It depends on this year’s exam questions. Once the scores are out, we’ll study the application issue."

"You really need to study that well. If it doesn’t work out, consult a professional teacher."

Yang Sen nodded affirmatively at Old Bai’s advice.

There are hundreds and thousands of universities nationwide, with tens of thousands of professional categories, and with the same college entrance exam scores, the choices might be hundreds or thousands.

How to find a suitable major among so many choices is a problem every parent and student faces, but cannot solve.

In most cases, choices are made based on the parents’ occupation and recommendation.

If parents have no knowledge, no occupation, and no capability, then it’s based on what the child likes, or rather, what they’ve heard of, and they choose a major based on that.

The better-case scenario is having recommendations from high school teachers.

There is also a fundamental issue of what the purpose of attending college is.

Some people attend college just to cultivate their taste and nurture their personality, and can return home to inherit the family business after graduating.

For them, college is not for employment, but for personal growth.

But for the vast majority, the purpose of attending college is for employment.

So what major should one choose to be favorable for employment?

"I’ve contacted a teacher here, but the fee is a bit high."

Yang Sen and Old Bai have talked about their child’s college entrance exam more than once.

It seems Yang Sen has already started taking action.

Most of these things are one-on-one consultations, but good consulting teachers are very scarce.

"If it’s a bit high, so be it," Old Bai is obviously aware of the market: "Last week, I heard from our neighbor that they made an appointment with a consulting teacher online."

"It was that particularly popular teacher, Mr. Feng, online, but they couldn’t get an appointment at all."

"Too expensive?"

"It’s not about the money, they’re fully booked, this year’s slots were gone long ago, and next year’s too, I heard they’re booked until the year after next."

"The year after next..."

This is a bit exaggerated, right?

While the two were chatting, Lu Chuan listened while working on the software.

Actually, Old Yang’s son’s grades are quite good.

Based on the scores in the recent mock exams, attending Public Security University is basically not an issue.

It just depends on whether the kid wants to be a police officer in the future.

As for other majors, at worst, he could work at Qiangsheng Group.

In Haizhou City, the employee benefits of Qiangsheng Group are famously good.

This can be seen from the hierarchy of dating preferences in Haizhou City.

Except for very few like the Fifth Wang, who have houses, cars, savings, and no parents or kids, a normal matchmaking order is Qiangsheng Group equated to having a secured job. 𝐟𝕣𝕖𝐞𝐰𝕖𝚋𝐧𝗼𝚟𝐞𝕝.𝗰𝐨𝐦

In terms of financial aspects, it might even be more popular.

With Lu Chuan’s status in the Lu Family, arranging a few people to work there is just a matter of saying it.

And it doesn’t matter what major, as Qiangsheng Group and its subsidiaries and branches, there are dozens to hundreds, can find a good job in any major.

The security guards of Qiangsheng Group earn over ten thousand a month.

Of course, not just anyone can be a security guard at Qiangsheng Group, they need real skills, it’s the most sought-after retired soldier settlement company in Haizhou City.

That’s one reason why Qiangsheng Group has been able to stand firm, it truly is a conscientious enterprise.

"Brother Yang, either become a police officer or go to Qiangsheng Group, no need to worry so much."

"Hey," Yang Sen and Old Bai turned around, seeing Lu Chuan getting up from the computer and walking towards them.

"Fingerprint processing done?"

Liu Guodong also came over, looking at Lu Chuan.

This case from the Taizhou City Criminal Investigation Team is not insignificant.

It was originally an ordinary homicide, even if it wasn’t solved, it wouldn’t be much.

At most, penalties would be placed by the end of the year.

In the current situation, although there’s a requirement that homicide cases must be resolved.

In reality, unsolved homicides occur every year.

Otherwise, where did so many cold cases of homicide originate?

Old cases aside, due to reasons such as technology, responsibility, and other factors, there are unsolved cases.

Even now, it’s the same.

Take Haizhou City for example, not many homicides occur each year.

Most homicides in recent years have been solved.

But what about missing person cases?

Missing person cases can’t be counted as homicides, but they may very well be homicides.

Given Haizhou City’s population size, having over a hundred missing person cases a year is common.

Some are reported, more aren’t possibly even reported.

Just like the bones in the bridge pier of Ming River in Qinzhou City, many died, yet were not discovered.

Even though technology is more advanced now, and systems are more complete, there are still homicides that cannot be solved.

But this case in Taizhou City involves an innocent person, who was arrested and committed suicide, making it not just an ordinary homicide.

Having worked in the public security system for so many years, Liu Guodong and the others are very aware of the stakes involved.

Thus, even though this case has nothing to do with Haizhou City, the three are very attentive to Lu Chuan’s fingerprint identification analysis result.

Lu Chuan stretched lazily, twisted his stiff neck, "Fingerprint separation has been successful, it’s running in the system."

Lu Chuan’s description was quite simple, but the recent operations were actually much more complex.

Fingerprint separation was one part, after separation, Lu Chuan also enhanced the fingerprints.

The main issue was that the ridgeline of the separated fingerprint was too fine, less than one-third the usual fingerprint ridgeline thickness.

In such cases, direct system comparison would 100% fail.

So, Lu Chuan outlined the separated fingerprint ridgeline.

Moreover, supplemented and adjusted some broken areas.

Only then was a fingerprint less than one-third the size of a normal fingerprint ultimately obtained.
