1. What is a search engine
Baidu Encyclopedia defines it like this: Search Engine (Search Engine) refers to collecting information from the Internet by using specific computer programs according to certain strategies, and providing users with search engine information after organizing and processing the information. Service, which displays information related to the user's search to the user's system. Search engines include full-text index, directory index, meta search engine, vertical search engine, aggregate search engine, portal search engine and free link list, etc. Simply put, a search engine is a platform for retrieving information.
Second, the advanced application of search engine
In fact, we ordinary people and non-professionals don’t need to understand what a search engine is. Here I will give you an example of commonly used large portal websites such as Baidu, Google, Sina, Sohu, etc. Among them, Baidu and Google are full-text search, also known as keyword search. ; Sina and Sohu are catalog search. Usually when we are doing PPT, we often need to insert pictures into the PPT to make the presentation of the PPT more vivid and intuitive, to enhance the reader or audience’s desire to read, and to generate a sense of substitution and resonance. There is a saying that a picture is worth a thousand words. Therefore, pictures are very important to PPT designers, and this article mainly talks about how to use full-text search engines to search for good pictures, and how to use Baidu to search pictures at an advanced level.
Baidu is a question-and-answer artifact that more than 90% of people will think of when they encounter something they don’t know at work. Little do they know that many people only know the tip of the iceberg. Today, let us uncover the useful and powerful side of Baidu. That's the Image filter.
3. When we need to go to Baidu to search for pictures, we only need to open Baidu Gallery, the URL is:
http://image.baidu.com/
As shown below:
After entering the official website of the picture, just enter the keywords you need, such as: numbered musical notation
Image filtering has three major functions:
(1) Screening of picture size
When we design PPT, we usually require our pictures to be high-definition. At this time, when we search, we can choose the size filter. We usually choose two options: "extra large size" or "large size". One, the images searched out in this way generally have a relatively high resolution. It is enough to make a PPT presentation.
(2) Color filter function
This function is generally applied to the production of PPT or posters. When our background is white, at this time we are limited to white when searching for pictures. The resulting image can be well blended into the background. For example, we are searching for: city silhouette
(3) Filter by type
This function is generally used by pressing "Face close-up" and "Static picture". When we want to insert a character in the PPT, and we need a close-up of the face of the character, we can use this function, for example, character introduction page design and more.
Fourth, the function of recognizing pictures with pictures
Baidu has a useful function that we can upload existing materials to find higher quality pictures. How to use this function? it's actually really easy.
When we search for a good picture on the Internet, but the size of this picture is too small to meet our production needs, at this time Baidu's image recognition function comes in handy.
The image search function is very useful:
(1) For the identified pictures, we can sort them according to size from large to small to find the largest size picture. Generally, it can meet our needs when making PPT.
(2) We can check the source of the picture, understand the copyright issues of the picture, etc.
(3) Search for related (similar) pictures. This function is very practical. When we can’t find the picture we want after searching online for a long time, we can search for pictures through similarity and change our thinking, and you will get unexpected surprises.
Well, I have to share it with you today. I hope everyone can support Baidu's advanced image search function. Search efficiently within your own work. Improve work efficiency.
Finally, I would like to remind everyone that no matter how small a skill is, it is worth treating with care, and it will bring unexpected surprises to your work!
