Chen Kun, who was frowning, was slightly stunned to hear Lu Chuan's voice.
Chen Kun had his own set of methods for image enhancement, and after many years of validation, it proved to be very effective.
This was also why Chen Kun didn't like using software that everyone else used; he used a very niche portrait processing software.
When Chen Kun was younger, someone had taught him how to do it.
Later, Chen Kun became a technical expert in the Image Investigation Brigade, securing the top position, and no one said anything anymore.
Moreover, Chen Kun was confident that if there was an image he couldn't process in the entire Haizhou City, it would be useless for others to try.
However, Lu Chuan's reminder was like a sudden enlightenment, breaking open Chen Kun's bottleneck.
He didn't care why Lu Chuan, a person from a Crime Scene Investigation and fingerprint analysis background, knew about the Fourier transform.
