325: Chapter 293 Celebrate 325: Chapter 293 Celebrate Jiang Yuan followed the members of the Duck Squad and watched the video for a while, getting familiar with the new surveillance system. It must be said, watching videos with a bunch of guys, especially sports videos dominated by guys, yet without a ball, what’s left is pure boredom. Zhuang Wei operated the software, tracking the whereabouts of a criminal suspect from the core area of the county district until he got into a car, the entire process... Jiang Yuan was super bored. It must be said that as the cases he worked on gradually increased, overly systematic cases really wore at his willpower. As Jiang Yuan watched, he couldn’t help but pull out his phone and began checking it. After not checking for a long time, several groups had already accumulated hundreds of new messages. There was a red “@” symbol in the “Shannan Fingerprint Exchange Group.” When Jiang Yuan clicked in, he saw that it was Li Zemin who had @’ed him. As a comrade-in-arms who had fought alongside each other in the province-wide fingerprint offensive, Li Zemin could be considered a breath of fresh air among the provincial experts. He and Jiang Yuan smoked Zhonghua cigarettes together, shuttled through major cases selected by the province together, and hacked away in chaos, from the first day to the fifteenth, without ever stopping. Feeling nostalgic, Jiang Yuan opened the “Shannan Fingerprint Exchange Group.” Shan Nan Li Zemin: “[@Jiang Yuan. Help me look at this fingerprint, a fool of a kid lifted it from the trunk’s lining fabric, and I highly suspect it belongs to someone with a previous record.]” Changyang City – Shuidong District – Forensic He Guohua: “[My Jiang is too busy, recently he’s cracked five or six murder cold cases in two months, and even found time to match fingerprints.]” Shan Nan Li Zemin: “[I always return tenfold for one favor. I’m asking Jiang Yuan to do one fingerprint analysis, and I’ll do ten miscellaneous tasks for him in return.]” Changyang City – Shuidong District – Forensic He Guohua: “[Brother Li, aren’t you boasting a bit too much?]” Shan Nan Li Zemin: “[But I’ve been keeping track. Just like the Zhonghua cigarettes I used to smoke with Jiang Yuan, I’ve written down how many it’s been, and if I don’t pay them all back, I’ll let my son do it.]” Zhu Huangguang of Southern Mountains: “[@Changyang City – Shuidong District – Forensic He Guohua, you’re a whole round older than Jiang, can you call him ‘bro’?]” Changyang City – Shuidong District – Forensic He Guohua: “[Brother Zhu, you’re right in your criticism. I shouldn’t mess up the seniority just because I’m in the group. Here in Changyang City, we now call him Master Jiang. Master Jiang, I won’t @ you any longer.]” Provincial Bureau – Fingerprint Post – Yang Ling: “[How about we call him God Jiang? If public security hears ‘Master Jiang’, it might lead to trouble.]” Jiang Yuan satisfyingly read another hundred or so messages, and once they started changing the subject, he forwarded the fingerprint that Li Zemin had sent to himself. Some things, if they’re too difficult to obtain, can make it hard to enjoy the glory and happiness they bring. On the contrary, if they are easily obtained, the feeling of happiness in one’s heart is actually stronger. It’s just like people who benefited from being relocated, or the second generation of such people. Just like Jiang Yuan. “Zhuang, lend me a computer for a moment. I need one with good performance,” Jiang Yuan said with the fingerprint in hand, feeling that the Image Investigation office was quite suited for fingerprint analysis. Here they also had a need for image processing, and the newly equipped computers used top configurations from two years ago. Zhuang Wei promptly freed up a computer for Jiang Yuan, typed in the boot password, and said with a smile, “The password is the police badge number.” “Alright. Thanks.” Jiang Yuan was not surprised at all. Using their police badge number for passwords was all too common among police officers, and many only changed this bad habit after their wives inspected their phones. A simple, incomplete fingerprint didn’t require any particularly special software. Jiang Yuan loaded it up and began processing it with Photoshop. Of course, Photoshop actually has nothing to do with simplicity. Used well, this tool could work wonders with photos. The term PS originally referred to processing with Photoshop. However, tasks requiring experts in the past have been simplified by various software programs, so that even those without technical knowledge and money could PS a bunch of beautiful pictures. However, Photoshop’s functionality had never diminished. Its wide range of applications went beyond just dealing with plump and pallid complexions. Many people simply weren’t skilled at using it. Its complex and potency made it beyond the reach of most image processors, increasing the difficulty of usage, causing many to choose software that imitated Photoshop’s functions as a substitute. Another issue was the prohibitive cost of a legitimate Photoshop license. “I’m processing a fingerprint for a friend who needs it,” Jiang Yuan explained to Zhuang Wei and began working on the computer. Zhuang Wei watched with a sense of sorrow. As before, when Jiang Yuan started enhancing the images, it was quite difficult for Zhuang to understand. But then—hey, Zhuang Wei suddenly realized that he sort of understood Jiang Yuan’s operation. In fact, fingerprint image enhancement was simpler than video image enhancement. This wasn’t just an issue of image complexity, but also one of familiarity. Zhuang Wei had been a police officer for over a decade and had seen countless fingerprints. He had a clear, rich experience of what a fingerprint should look like in his mind. So watching Jiang Yuan do image enhancement, he might not have an intuitive feeling, but watching Jiang Yuan work with fingerprints, he suddenly understood the direction and goal of Jiang Yuan’s operations. Knowing the destination made it easier to understand the process involved. Moreover, Jiang Yuan hadn’t used any particularly complex techniques. He just needed to process the fingerprint cleanly. Even saying that, he didn’t need to process the entire fingerprint; just a part of it made nice and clear was enough. With his LV3+LV4 fingerprint analysis technique, even if only one-third of the fingerprint was basically clear, Jiang Yuan could get enough information—assuming the fingerprint to be compared was complete and clear. And this time, the target fingerprint belonged to a repeat offender, so clarity wouldn’t be too much of a concern. So, robust fingerprint analysis and powerful image enhancement go hand in hand. Anyone who has used Photoshop knows that the software’s image processing also frequently involves sacrifices. If you’re only dealing with a small part of an image, the difficulty is reduced. Therefore, Jiang Yuan was able to obtain a small but very clear piece of fingerprint more easily. And a consistent, complete fingerprint has, in fact, more advantages in fingerprint comparison. Zhuang Wei easily discerned Jiang Yuan’s strategy. At this point, as he watched Jiang Yuan enhance images further, he slowly became immersed. To speak of it, Zhuang Wei’s fundamentals were not bad; he had studied a related major in college over a decade ago. Plus, it’s well-known that concepts involving digital image processing, like Fourier transforms and discrete functions, haven’t changed much over the past decade or so. In other words, as long as a person is diligent, eager to learn, and strives to improve, even if a bit slow, but can understand discrete functions, handle power transformations, and master the segmented linear transformation function relatively skillfully, then even if they have to spend several times more effort learning math, they won’t be easily eliminated by society. Like Zhuang Wei, he had not spent much time studying in the past decade, but this was mainly because he lost the environment conducive to learning. Most people are like that; once they start working, they begin endless output, because of pressure, responsibility, desires... When everything is judged on quantity, 3000, 6000, 9000, or 12000 are only meaningful in the moment. Jiang Yuan carved out a path for Zhuang Wei. During the time when Jiang Yuan was enhancing the images, Zhuang Wei’s mind suddenly recalled many pieces of knowledge he thought he had forgotten, and he even began to feel that being the leader of the Surveillance Analysis Squad didn’t matter much. Even being the head of the Image Reconnaissance Brigade—if he could truly achieve that, as the original Four-Eyes Duck, he felt it was his duty. “That should do it,” Jiang Yuan withdrew his hands. Zhuang Wei’s mind cleared suddenly, “Ah, is it done?” “Yes, I need to compare the fingerprints, might need some adjustments, but it’s basically like this.” Jiang Yuan actually knew that Zhuang Wei was stealing techniques, but he didn’t mind and even casually gave Zhuang Wei a few pointers. Some things, if you can learn, don’t need to be stolen; for those that can’t be learned, not even force-feeding will work. The completed fingerprint image was uploaded into the software and, with only one marking of feature points, the identical fingerprint was found at the 8th position. It was a very high priority on the list; as Li Zemin said, the fingerprint indeed belonged to a criminal with a prior record. It must be said, the judicial system of Shannan Province really did a good job with fingerprint registration. Jiang Yuan clicked submit and then took out his phone. Zhuang Wei was slightly dazed and asked, “Did it match?” “Yes.” “Hm... a homicide?” “Shouldn’t be, I didn’t ask about the specifics of the case. Let me inform Brother Li,” Jiang Yuan said as he took out his phone and dialed Li Zemin. Li Zemin almost picked up the call instantly. From the receiver, Li Zemin’s amplified laughter was heard, “Hahaha, I just knew it, Jiang Yuan dealing with fingerprints is a matter of minutes. Did it match?” “It did, although it also took nearly two hours,” Jiang laughed, “We need to be precise about the time, otherwise, you’d say I was neglecting it.” “How could that be, from the first time you passed me a cigarette, I knew I’ve got a brother in you.” “When you’re in the area on a trip, I’ll treat you to a cigar.” “Damn, wait for it... oh, I see the fingerprint you submitted in the backend, expert review isn’t finished yet, alright, I’ll go notify the arrest team.” Although Jiang Yuan was a provincial hall-certified fingerprint expert, able to conduct expert reviews himself, fingerprints he processed still required review by others. The domestic requirements for the accuracy of fingerprint evidence are very high. After Jiang Yuan responded, he then asked, “What kind of case is it?” “Definitely a homicide. Would I dare to bother you with a small case? But it’s a fresh case. Judging by the scene, looks like a repeat offender leveling up in crime...” Li Zemin quickly explained a bit before hanging up to report. Jiang Yuan put down the phone and smiled at Zhuang Wei who had clearly overheard, “I really didn’t expect it to be a homicide.” “That’s true,” Zhuang Wei’s smile carried a trace of helplessness, “Who would have thought that a fingerprint, which a fingerprint expert couldn’t decipher, and had to ask someone else for comparison, would be for a homicide.” Buzz. Jiang Yuan’s phone lit up momentarily. The “Shannan Fingerprint Exchange Group” flashed red again: Shan Nan Li Zemin: [Thanks to my brother Jiang Yuan for matching a fingerprint in a murder case for our city, scatter flowers!] Changyang City – Shuidong District – Forensic He Guohua: [God Jiang, you’re truly the best, scatter flowers!] Zhu Huangguang of Southern Mountains: [Review passed. Scatter flowers] Provincial Hall – Fingerprint Desk – Yang Ling: [Ningtai Jiang Yuan, a fierce blaze.]
