What is Mosaic ? What is Mosaic

Broken Bridge Maple's is more interesting.,Hahaha。。。

This method degrades the gradation details in a specific area of the image and causes the effect of color blocks being scrambled, because this blur seems to be composed of small grids, so it is vividly called a mosaic. The purpose is usually to make it unrecognizable, and it usually appears in news reports to obscure the person's face.

For example, there are many 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). Mosaics are usually hit on the eyes, and the reason why they are hit on the eyes is because the human eye is an important part of the human face that has a distinguishing role, and blurring this part will make it difficult for people to identify the other person.

The principle and function of mosaic

Let's take RGB as an example, 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 it is, for example, bright red uses an r-value of 255, a g-value of 0, and a b-value of 0, and the colored light rolling clear can be diluted and lightened by the 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.

The purpose of the mosaic itself is to hide some information that is private and does not want to be known to the general public. Once the mosaic is eliminated, it is equivalent to the coding of ** or ** will be invalid, so that some private, harmful, and unwilling parts of the public will be exposed to the sun.

The original meaning of mosaic is: inlay, mosaic, inlay process.

Mosaic can be divided into several different types according to the material and process, glass mosaic can be divided into machine single-sided cutting, machine double-sided cutting and manual cutting according to its process, and non-glass mosaic can be divided into ceramic mosaic, stone mosaic, metal mosaic and so on according to its material.

Another meaning is the image (**) processing method, which makes it partially blurred, because this blur seems to be composed of small grids, so it is vividly called this kind of picture mosaic. Mosaics are often used to obscure important areas.

It is a block that can block things.
