 This pipeline **cannot be run**, which is the **template for the image embedding pipeline class** and defines YAML template file for embedding images, as well as the standard inputs and outputs. You can complete the pipeline by filling in the parameters(`init_args`) of the Operator section in [image_embedding_pipeline_template.yaml](./image_embedding_pipeline_template.yaml) and update this README file. FYI, [image-embedding-resnet50](https://hub.towhee.io/towhee/image-embedding-resnet50) is based on this template.

 ## **How it works**
 
-This pipeline includes two main operators: [transform image](https://hub.towhee.io/towhee/transform-image-operator-template)  and [image embedding](https://hub.towhee.io/towhee/image-embedding-operator-template). The transform image operator will first convert the original image into a normalized format, such as with 512x512 resolutions. Then, the normalized image will be encoded via image embedding operator, and finally we get a feature vector of the given image.
+This pipeline includes one operator: [image embedding](https://hub.towhee.io/towhee/image-embedding-operator-template). The image will be encoded via image embedding operator, then we can get a feature vector of the given image.
