What is mosaic and why mosaic

Generally refers to making part of the image blurry, such as mosaicing some people's faces in TV reports to protect privacy - I hope to solve the landlord's problem, forget, thank you.

It is to add a mosaic effect to the places that you don't want people to see, that is, the picture becomes a small grid composed of pieces of things that cannot be seen clearly.

、、、If you don't even know this, I don't know how to explain it to you.

The aim is usually to make it unrecognizable. For example, there are a lot of small color blocks of different colors among them, because the pixels of these color blocks are very, very small and dense, and mosaic is to circle a range (small color blocks are integer ranges, so they are generally circled with rectangles or squares).

For example, RGB is used, R (Red), G (Green), B (Blue). Each of these three colors has an intensity value in the range of 0 255, with the higher the number, the brighter;

For example, bright red uses an r-value of 255, a g-value of 0, and a b-value of 0, and colored light can be diluted and lightened by colorless light. If blue light meets white light, the result is a brighter, light blue light. So the values of r, g, and b are different to mix the colors.

Because something doesn't want to be seen.

Mosaic means: the effect of degrading the gradation details in a specific area of the image and causing the color blocks to be confused, because this blur seems to be composed of small grids, so the image is called mosaic, and its purpose is usually to make it unrecognizable.

It also refers to software with other things that are not suitable for display, such as H, and some people who love it will cover up these things that are not suitable for appearing, and these things are translucent (blurry). Prevent others from ** coming, these things are in the shape of a lattice, so they are also called mosaics.

Frame loss caused by network transmission quality problems will also form mosaics, and the commonly used network technologies can alleviate the influence of mosaics to a certain extent.

Mosaic parts:

1. Sensitive parts. This kind of general involves sexual aspects, and if you don't play mosaic, it will become an FBI warning.

2. Eyes. This is a more common way to code mosaics, which is to hit the face, or eyes to be exact. We can understand that after all, the human face is the main differentiating feature of the human body, and it is basically difficult to distinguish a specific individual by removing the face.

The face has several structures, from top to bottom, the forehead, eyes, nose, lips, and face. Among these structures, the eye is the most critical feature part, because the eye itself is changeable, not only the difference in the color of the pupil, but also the shape of the eye, and the most important thing, the eye.

Mosaic is not allowed to be seen by others, because these are private and can only be viewed by oneself.

Mosaicing refers to the effect of degrading the gradation details in a specific area of the image and causing the color blocks to be disrupted, making it difficult to see the specific picture.

Because the blur of mosaic seems to be composed of small grids, this kind of picture is called mosaic. The aim is usually to make it unrecognizable.

For example, there are a lot of small color blocks of different colors among them, because the pixels of these color blocks are very, very small and dense, and mosaic is to circle a range (small color blocks are integer ranges, so they are generally circled with rectangles or squares).
