Chapter 821： Blue Screen Technology

"My friend who is a physics expert once told me something about quantum mechanics in physics."

"The phenomenon he said proves that the interference results after the particles are emitted are the same. That is, one kind of particles interferes with another kind of particles." The patient said.

Mu Qiu knew what the patient wanted to express, and said, "I know that the relationship between these particles is unconditionally related, because there are many such experiments."

"Because one kind of particle affects another kind of particle, so that the kinetic energy of these two kinds of particles can be changed, this kind of inexplicable change, there are too many things like this, but everyone knows why."

After Mu Qiu finished speaking, the patient nodded, indicating that he knew what Mu Qiu had said.

But Mu Qiu was not as calm as the patient, and the reaction was a bit strong.

"Huh?" Mu Qiu couldn't help but get excited. No matter whether the patient really knew it or not, but the only thing that is certain is that someone who can say this is at least worthy of Mu Qiu's contact.

"Let's play a fun game. It should be a fun experiment."

"You should know the blue screen technology that is often used in those movies and TV series?" the patient asked.

Blue screen technology is also called chroma key technology. Simply put, it uses the background color to distinguish the foreground from the background by shooting objects on the background of the same color, so as to achieve the purpose of automatically removing the background and preserving the foreground.

It is widely used in the dynamic background synthesis of broadcast and television, as well as the creation of movies and photography.

The blue screen technology does not necessarily have to use the blue screen as the background. In principle, you only need to choose a color that the foreground subject does not have as the background.

Correctly used blue screen technology, in addition to correctly extracting the foreground, you can also extract the semi-transparent areas and shadow areas in the foreground.

"I know this." Mu Qiu said.

"That's great, so we will do it with that technique now," the patient said.

"Oh, how do we do it? Do you have any method?" Mu Qiu asked, curious about what kind of fancy ideas this patient would come up with.

After hearing Mu Qiu’s question, the patient said with a smile: “First, we first find a snake, then we remove the tongue and tail, dye the middle part blue, and then we put the snake on the blue blanket. Take it with the camera again."

"Then I will show it to you, what will you see then?" the patient said.

"I may only see the snake's head and tail moving, but I may not see the snake's body." Mu Qiu said.

When Mu Qiu finished speaking, she suddenly realized that she seemed to understand something.

"Ah, this way, I seem to understand." Mu Qiu said excitedly.

Seeing Mu Qiu's reaction like this, the patient said with disgusting eyes and impatiently: "Can you not make that shocking sound every time?"

"Hmm, sorry, let's go on!" Mu Qiu said awkwardly.

"It's okay, it's the meaning you understood just now."

"Between the snake head and the snake tail, there is a body painted blue to connect, but you can't see it in the picture after shooting." The patient said.

"That's right! It's just that you can't see the picture after shooting. It's just that you can't see it. It doesn't mean that it doesn't exist." Mu Qiu added.
