# tfjs-yolov3
## 介绍
完全用js来实现图片中的目标检测
基于yolov3算法和Tensorflow.js库
用tensorflow.js实现yolov3和yolov3-tiny
需要注意的是: 必须是[email protected]版本以上
## 特点
- 可以识别**任意尺寸**的图片
- 同时支持yolov3和yolov3-tiny
## 快速开始
### 安装
```
npm install tfjs-yolov3
```
### 用法示例
```javascript
import { yolov3, yolov3Tiny } from 'tfjs-yolov3'
async function start () {
const yolo = await yolov3Tiny() // pre-load model (35M)
// or
// const yolo = await yolov3() // pre-load model (245M)
const $img = document.getElementById('img')
const boxes = await yolo($img)
draw(boxes) // Some draw function
}
start()
```
## API 文档
yolov3和yolov3Tiny函数接受一个options对象，并返回一个函数
```typescript
export declare function yolov3 (
{ modelUrl, anchors }? :
{ modelUrl?: string, anchors?: number[] }
): Promise
export declare function yolov3Tiny (
{ modelUrl, anchors }? :
{ modelUrl?: string, anchors?: number[] }
): Promise
```
| 参数 | 说明 |
| ------------ | ------------ |
| modelUrl | 可选，预训练model的url，可把model下载到本地，加快预训练model的加载速度，[点我下载](https://github.com/zqingr/tfjs-yolov3/releases/tag/v1.0) |
| anchors | 可选，可自定义anchores，格式参考[config](https://github.com/zqingr/tfjs-yolov3/blob/master/src/yolo/config.js) |
这两个函数调用后会加载预训练model，并返回一个函数，可用这个函数去识别图片，并返回识别后的box列表，参数如下：
```typescript
type yolo = ($img: HTMLImageElement) => Promise
interface Box {
top: number
left: number
bottom: number
right: number
width: number
height: number
scores: number
classes: string
}
```
