-# image-embedding-operator-template
+# Template: Image Embedding Operator
 
-This is another test repo
\ No newline at end of file
+Authors:
+
+## **Overview**
+
+> <font color=red>**Note:** this is just a **template**, not a runnable pipeline.</font>
+
+This **class template for the image embedding operator** defines the image embedding functions, as well as the standard inputs and outputs. You can complete the operator by filling in the function(`__init__`, `__call__` ) in [image_embedding_operator_class.py](http://./image_embedding_operator_class.py) and update this README file. FYI, [image-embedding-resnet50](https://hub.towhee.io/towhee/image-embedding-resnet50) is based on this template.
+
+This Operator generates feature vectors from "someone" model, which is trained on "someone" dataset.
+
+## **Interface**
+
+```python
+__init__(self, model_name: str, framework: str = 'pytorch')
+```
+
+**Args:**
+
+- model_name:
+  - the model name for embedding
+  - supported types: `str`, for example 'resnet50'
+
+- framework:
+  - the framework of the model
+  - supported types: `str`, default is 'pytorch'
+
+```python
+__call__(self, img_tensor: torch.Tensor)
+```
+
+**Args:**
+
+- img_tensor:
+  - the input image tensor
+  - supported types: `torch.Tensor`
+
+**Returns:**
+
+The Operator returns a tuple `Tuple[('feature_vector', numpy.ndarray)]` containing following fields:
+
+- feature_vector:
+  - the embedding of the image
+  - data type: `numpy.ndarray`
+
+## **Requirements**
+
+You can get the required python package by [requirements.txt](https://zilliverse.feishu.cn/docs/requirements.txt).
+
+## **How it works**
+
+The `towhee/image-embedding-operator-template` Operator implements the function of image embedding, which can add to the pipeline. For example, it's the key Operator named embedding_model within [image-embedding-pipeline-template](https://hub.towhee.io/towhee/image-embedding-pipeline-template) pipeline, and it is the red box in the picture below.
