How to perform image recognition and face comparison in Vue
With the development of artificial intelligence, image recognition and face recognition technologies have been widely used in various applications. As a popular front-end framework, Vue provides many utilities and libraries that can help us in image recognition and face recognition in our applications. In this article, we will introduce how to use Vue for image recognition and face comparison.
Image Identification
Image recognition is a computer vision technique that analyzes the content of an image to identify the object it represents. In Vue, third-party APIs such as Baidu AI and Tencent AI can be used to realize image recognition.
Baidu AI
Baidu AI provides a series of image recognition APIs, including image classification, image search, face recognition, etc. In the Vue project, you can use Baidu AI's JavaScript SDK to call these APIs.
Install Baidu AI SDK
In a Vue project, you can use the npm package manager to install the Baidu AI SDK.
npm install baidu-aip-sdk
Implement image classification
Below is a simple Vue component that demonstrates how to use Baidu AI to implement image classification.
<template>
<div>
<input type="file" @change="handleFileSelected">
<button @click="classifyImage">Classify Image</button>
<div v-if="result">
<p><strong>Result:</strong> {
{ result }}</p>
</div>
</div>
</template>
<script>
import AipImageClassifyClient from 'baidu-aip-sdk/imageClassify'
export default {
data() {
return {
file: null,
result: null
}
},
methods: {
handleFileSelected(event) {
this.file = event.target.files[0]
},
async classifyImage() {
if (this.file) {
const imageClassifyClient = new AipImageClassifyClient(
'yourAppId',
'yourApiKey',
'yourSecretKey'
)
const fileReader = new FileReader()
fileReader.readAsDataURL(this.file)
fileReader.onload = async () => {
const image = fileReader.result.split(',')[1]
const result = await imageClassifyClient.advancedGeneral(image)
this.result = result.result[0].root
}
}
}
}
}
</script>
In this component, we use Baidu AI's JavaScript SDK to classify images into the objects they represent. In classifyImagethe method, we first create an AipImageClassifyClientobject and use that object to call advancedGeneralthe method to classify the image. Finally, we store the classification result in resulta property of the component and display it on the page.
Tencent AI
Tencent AI also provides a series of image recognition APIs, including image labeling, object recognition, face recognition, etc. In the Vue project, you can use Tencent AI's JavaScript SDK to call these APIs.
Install Tencent AI SDK
In the Vue project, you can use the npm package manager to install the Tencent AI SDK.
npm install tencentcloud-sdk-nodejs
Implement image tags
Below is a simple Vue component that demonstrates how to use Tencent AI to implement image tags.
<template>
<div>
<input type="file" @change="handleFileSelected">
<button @click="tagImage">Tag Image</button>
<div v-if="result">
<p><strong>Result:</strong> {
{ result }}</p>
</div>
</div>
</template>
<script>
import tencentcloud from 'tencentcloud-sdk-nodejs'
export default {
data() {
return {
file: null,
result: null
}
},
methods: {
handleFileSelected(event) {
this.file = event.target.files[0]
},
async tagImage() {
if (this.file) {
const ImageClient = tencentcloud.image.v20190111.Client
const clientConfig = {
credential: {
secretId: 'yourSecretId',
secretKey: 'yourSecretKey'
},
region: 'yourRegion',
profile: {
httpProfile: {
endpoint: 'image.tencentcloudapi.com'
}
}
}
const imageClient = new ImageClient(clientConfig)
const fileReader = new FileReader()
fileReader.readAsDataURL(this.file)
fileReader.onload = async () => {
const image = fileReader.result.split(',')[1]
const params = {
ImageBase64: image
}
const result = await imageClient.TagDetect(params)
this.result = result.Tags.map(tag => tag.TagName).join(', ')
}
}
}
}
}
</script>
In this component, we use Tencent AI's JavaScript SDK to tag images. In tagImagethe method, we first create an ImageClientobject and use that object to call TagDetectthe method to label the image. Finally, we store the tagged result in resulta property of the component and display it on the page.
face comparison
Face comparison is a computer vision technique that compares the similarity of two images of faces to determine if they belong to the same person. In Vue, third-party APIs such as Baidu AI and Tencent AI can be used to achieve face comparison.
Baidu AI
Baidu AI provides a series of face recognition APIs, including face search, face comparison, etc. In the Vue project, you can use Baidu AI's JavaScript SDK to call these APIs.
Realize face comparison
The following is a simple Vue component that demonstrates how to use Baidu AI to achieve face comparison.
<template>
<div>
<input type="file" @change="handleFileSelected(1)">
<input type="file" @change="handleFileSelected(2)">
<button @click="compareFaces">Compare Faces</button>
<div v-if="result">
<p><strong>Result:</strong> {
{ result }}</p>
</div>
</div>
</template>
<script>
import AipFaceClient from 'baidu-aip-sdk/face'
export default {
data() {
return {
files: [],
result: null
}
},
methods: {
handleFileSelected(index, event) {
this.files[index - 1] = event.target.files[0]
},
async compareFaces() {
if (this.files.length === 2) {
const faceClient = new AipFaceClient(
'yourAppId',
'yourApiKey',
'yourSecretKey'
)
const fileReaders = []
for (const file of this.files) {
const fileReader = new FileReader()
fileReader.readAsDataURL(file)
fileReaders.push(fileReader)
}
Promise.all(fileReaders).then(async () => {
const images = fileReaders.map(fileReader => fileReader.result.split(',')[1])
const results = await Promise.all(images.map(image => faceClient.detect(image)))
const faceTokens = results.map(result => result.result.face_list[0].face_token)
const result = await faceClient.match(faceTokens)
this.result = result.result.score
})
}
}
}
}
</script>
In this component, we use Baidu AI's JavaScript SDK to compare two face images. In compareFacesthe method, we first create an AipFaceClientobject and use this object to call the detectmethod to detect faces. We then store the detected faces face_tokenin an array and use matchthe method to compare the two face_token. Finally, we store the comparison result in resulta property of the component and display it on the page.
Tencent AI
Tencent AI also provides a series of face recognition APIs, including face detection, face comparison, etc. In the Vue project, you can use Tencent AI's JavaScript SDK to call these APIs.
