Program apes use "beauty" to break through face recognition
Program apes use "beauty" to break through face recognition
First of all, it is not a serious and serious discussion of some IT technology, but it does not represent the content and view of the article without any technical content. Secondly, I have obtained the consent of my girlfriend when writing this article, and I have no history of mental illness, so please rest assured to read.
The traditional face recognition technology mainly includes "geometric feature based method", "template based method" and "model based method". "Geometric feature method" is to derive a set of feature vectors by using the feature point position of several important organs of the face as classification features, which include the distance. From the angle of angle and so on, each face picture calculates the corresponding similarity through the respective feature vector to carry on the face recognition and judgment, but because the number of feature points is too few, and the sensitivity of the feature point is not high, so the accuracy of the method is not high.
The "template based approach" is an improvement of the "geometric feature method", adding a "loss function" (Cost Function), by adjusting and optimizing the loss function to minimize the accuracy of the corresponding model when the function is minimized, but the amount of calculation in this way is too large and requires a large amount of preprocessing and fine reference. Number selection, neural network is one of the "template based methods". In the model based method, the better elastic map matching technique is a recognition algorithm which combines the geometric features and the grayscale distribution information with the wavelet texture analysis. However, the time complexity of the algorithm is high, the speed is slow, and the realization is complex. If these methods are comprehensively compared based on the cost and accuracy, the face detection scheme based on "neural network" will have more advantages. But these techniques are based on the results of face judgment based on the characteristics of two-dimensional image information. Is their robustness reliable?
Original
Before make-up, we first use unprocessed original pictures to detect face and record the effect before make-up. Here I directly selected photos of the head, and the face detection platform was selected. It can be seen that the gender is correct in the test results, but the accuracy rate of age estimation is not high, and the feature points of the face are accurately located.

Make-up
This part of my make-up is mainly to introduce the basic skin care and make-up process of my own commonly used, the concrete makeup tutorials and products all through related video to learn and buy more detailed and clear, after all, a lot of attention to the details is difficult to use a few pictures to describe clearly.
Skin care before makeup
The most important part of a delicate makeup is the bottom makeup. The quality of the bottom makeup directly determines the final effect of make-up. The makeup before skin makeup process directly determines the quality of the makeup. A simple and general makeup skin care process is described in Flowchart.

The dashed box represents the optional process. The first step is to clean the skin with clean water, which is commonly known as face washing. In the process of cleansing the need to use facial cleansing milk to see the individual, because the cleanser has a strong cleanser deoiling effect, so most of them contain surface activators, not more than two times a day. Generally we use facial cleanser to clean the skin thoroughly before going to bed. If it is the need for makeup the next morning, the second day morning cleaning process will not recommend the use of facial cleanser again. Of course, it varies from person to person. If your skin oil is particularly serious about the makeup process, it may still take a thorough cleaning process.
After cleansing, it is an optional mask process. This process is not necessary. But if you are a serious dry skin, consider adding a moisturizing mask. Follow up water, essence and emulsion are commonly used routines, and are also necessary steps in daily skin care. I'm using Innisfree's green tea water and the essence of pomegranate. Of course, you can also choose some men's special products, but basically the same.
Here is the basic function of essence, water and emulsion. The water here generally refers to make-up water or toner, mainly used to replenish moisture quickly for the skin and restore the acid-base balance of the skin. The main function of emulsion is to moisturize and replenish nutrition. Essence generally contains high concentration of skin care components, mainly used for wrinkle, moisturizing, whitening and antiaging, and to a certain extent the problem of the skin can be corrected.
Make-up
Make-up is a very big topic. Every part of the painting has great knowledge. First, I summarize the general process of make-up part of my make-up by a Flowchart.

The basic process is shown as shown in the figure above:
Repair (black eye, Hu Qing). First of all, beard as a man's secondary characteristics of course to be the focus of course, the first to shave, for some of the green heavy, the foundation hard to shield the child's shoes can be tried to cover with concealer and concealer, and then use a high cover to treat the foundation. Similarly, for those who often stay up late, dark circles must be treated with Concealer / liquid. The color number of Concealer needs to be darker than that of the face.
Base / air cushion CC. The next step is the process of foundation. Here you can choose a liquid foundation or a CC air cushion. What kind of mood can be used to see the mood? There is no obvious difference in personal feeling. On the foundation of the foundation
