92: Chapter 92 Group-Based Sparse Representations for Image Restoration

I have to say, my Li Yan is quite good-looking.

The key is that figure...

Curvy in all the right places, wearing high heels, her temperament is also very impressive...

Most importantly, her cleavage is also surprisingly magnificent...

Shaking his head, Zhao Yang temporarily put these messy thoughts aside.

Lost in thought, Zhao Yang had already returned to the dormitory.

There was no one in the dormitory.

Since Wang Mian and Li Tianqi joined the Game Club together, and Sun Xu started working at the school cafeteria, they almost never stayed in the dormitory once the weekend arrived.

Each had their own things to do.

Zhao Yang returned to his seat; today, he was going to start wrapping up this thesis of his.

Thesis Title: "Group-based Sparse Representation for Image Restoration"

[Abstract: Image restoration is one of the most fundamental and challenging problems in the fields of low-level computer vision and image processing.

During the acquisition, transmission, and storage of images, the original image often degrades due to the physical limitations of imaging equipment or environmental interference, suffering from noise pollution, blurring, or missing pixels...]

Zhao Yang concentrated his mind on writing this thesis.

"Over the past few decades, models based on sparse representation have become the mainstream method for solving image restoration problems.

This theory is based on a core assumption: natural image signals are sparse in a specific transform domain (such as wavelet transform, DCT transform) or under an over-complete dictionary.

However, these methods mainly focus on the local structure of image blocks and often ignore another important characteristic widely present in natural images—non-local self-similarity. That is, a texture structure in one part of an image often repeats in other positions of the image..."

Zhao Yang focused his attention.

This thesis was a relatively famous one that Zhao Yang had looked up before; it was a paper his mentor had asked him to find back then.

He had always had a deep impression of this thesis because he had used some of the content within it before.

Therefore, he had an extremely profound impression of its core theory.

It was just that his memory of some of the algorithms inside wasn't deep enough.

What Zhao Yang had done previously was mainly look up current research results while organizing and perfecting the algorithms.

He conducted his computational research very seriously.

On this thesis, Zhao Yang expended two hundred percent of his usual diligence.

After all, Zhao Yang intended to publish this thesis in a Tier 1 journal of the Chinese Academy of Sciences; a paper of this level could not be handled carelessly!

Focusing all his concentration on the thesis, Zhao Yang had almost no perception of the outside world.

Zhao Yang had no idea at all when Li Tianqi and Wang Mian returned.

"Whew!"

After writing the final word of the thesis, Zhao Yang let out a long breath. He stood up and stretched.

Only now did he suddenly realize that his three roommates had all returned to the dormitory.

He glanced at the time; it was already ten o'clock at night!

Zhao Yang felt a bit dazed.

He had returned to the dormitory at three in the afternoon.

To wrap up this thesis, he had stayed up until ten at night. After such a long time of intense concentration, Zhao Yang felt his whole being was somewhat exhausted.

"Brother Yang, finished writing the thesis?"

Seeing Zhao Yang stand up, Li Tianqi, who was nearby, smiled slightly and asked him.

"Yeah. When did you guys get back?"

Zhao Yang looked at Li Tianqi and Wang Mian curiously as he asked.

"The two of us got back after seven. Ah Xu came back a bit later, probably around eight-thirty. We saw you writing your thesis seriously as soon as we got back.

We didn't even dare to breathe too loudly!"

Li Tianqi said to Zhao Yang with a smile.

"Thanks!"

Zhao Yang said to his three roommates.

"No need, no need!"

Hearing Zhao Yang's thanks, the three roommates nearby spoke up hurriedly.

"Brother Yang, you writing your thesis is serious business. We've only been back in the dorm for a little over two hours; it was just a matter of not chatting, it's no big deal."

Wang Mian said quickly.

"Exactly! Brother Yang! Saying that makes it seem like you don't even see us as brothers! Brothers should help each other out! Besides, we didn't do anything! We just held it in for two hours!

It's a small matter!"

Li Tianqi also said with a slight hint of dissatisfaction.

"Yeah!"

Sun Xu, who usually didn't like to talk much, also spoke up rarely at this moment.

"If it weren't for your help, Brother Yang, I'd still be thinking about how to get a meal every day! This current job is so good; not only can I get a monthly salary of four hundred yuan,

but I can also eat so well every meal without having to pay!"

Sun Xu's eyes were full of gratitude as he looked at Zhao Yang.

"Once this month's salary is paid, I'll treat everyone to a meal! If everyone hadn't looked after me, I..."

As he spoke, Sun Xu looked at his three roommates before him.

"No need."

Zhao Yang said directly.

"Yeah, Sun Xu, your hands aren't exactly full of cash right now, we can't possibly..."

Li Tianqi also spoke up quickly from the side.

Hearing Zhao Yang and Li Tianqi's words, Sun Xu's expression suddenly turned a bit dim.

"Wait until you get a scholarship, then treat us to a meal! Four hundred yuan is too little, even though you don't spend money on food now.

But you always need to keep some money on you for daily necessities, stationery, or even buying some reference materials.

When you get a scholarship and treat us then, your three roommates won't feel any guilt in their hearts. What do you think?"

Zhao Yang looked at Sun Xu.

Sun Xu was stunned for a moment, then nodded after a brief silence.

"Alright, I still need to re-organize this thesis."

"Brother Yang, go ahead and get busy!"

Wang Mian said quickly.

After finishing his conversation with his three roommates, Zhao Yang sat back in his seat and began organizing his thesis.

This thesis of his was written entirely in English. After all, since he intended to publish in a foreign journal from the start,

it would naturally be more convenient to write the thesis directly in English.

Although Zhao Yang felt this practice was very inconvenient.

Clearly his mother tongue was Chinese, and the Dragon Country was a powerful nation in this world.

Yet, almost all mainstream academic journals in this world used English. Never mind this era; even by the time Zhao Yang was reborn, over a decade later,

English was still the absolute hegemon in the academic field, while Chinese journals were always on the extreme fringes.

Thinking of this, Zhao Yang sighed softly.

Once he had the ability, he would definitely do his best to change this status quo!

Especially in the later generations!

Clearly the Dragon Country had become the world's leading nation in scientific research, yet the status of Chinese journals was truly... too marginalized.

This was clearly wrong!

Sighing, Zhao Yang continued to input the thesis into the computer.

During this process, Zhao Yang took the opportunity to re-familiarize himself with his thesis and made certain edits to parts of the grammar, vocabulary, and even the content.
