-# japanese-clip
+#Japanese Image-Text Retrieval Embdding with CLIP
+
+*author: David Wang*
+
+
+<br />
+
+
+
+## Description
+
+This operator extracts features for image or text with [Japanese-CLIP](https://github.com/rinnakk/japanese-clip
+) developed by [rinna Co., Ltd](https://rinna.co.jp/), which can generate embeddings for Japanese text and image by jointly training an image encoder and text encoder to maximize the cosine similarity.
+
+<br />
+
+
+## Code Example
+
+Load an image from path './teddy.jpg' to generate an image embedding. 
+
+Read the text 'スケートボードに乗っているテディベア。' to generate an text embedding. 
+
+ *Write the pipeline in simplified style*:
+
+```python
+import towhee
+
+towhee.glob('./teddy.jpg') \
+      .image_decode() \
+      .image_text_embedding.japanese_clip(model_name='clip_vit_b32', modality='image') \
+      .show()
+
+towhee.dc(["スケートボードに乗っているテディベア。"]) \
+      .image_text_embedding.japanese_clip(model_name='clip_vit_b32', modality='text') \
+      .show()
+```
+<img src="https://towhee.io/image-text-embedding/clip/raw/branch/main/vec1.png" alt="result1" style="height:20px;"/>
+<img src="https://towhee.io/image-text-embedding/clip/raw/branch/main/vec2.png" alt="result2" style="height:20px;"/>
+
+*Write a same pipeline with explicit inputs/outputs name specifications:*
+
+```python
+import towhee
+
+towhee.glob['path']('./teddy.jpg') \
+      .image_decode['path', 'img']() \
+      .image_text_embedding.japanese_clip['img', 'vec'](model_name='clip_vit_b32', modality='image') \
+      .select['img', 'vec']() \
+      .show()
+
+towhee.dc['text'](["スケートボードに乗っているテディベア。"]) \
+      .image_text_embedding.japanese_clip['text','vec'](model_name='clip_vit_b32', modality='text') \
+      .select['text', 'vec']() \
+      .show()
+```

+<img src="https://towhee.io/image-text-embedding/clip/raw/branch/main/tabular2.png" alt="result2" style="height:60px;"/>
+
+

+
+
+
+## Factory Constructor
+
+Create the operator via the following factory method
+
+***japanese_clip(model_name, modality)***
+
+**Parameters:**
+
+​   ***model_name:*** *str*
+
+​   The model name of CLIP. Supported model names: 
+- japanese-clip-vit-b-16      
+- japanese-cloob-vit-b-16
+
+
+​   ***modality:*** *str*
+
+​   Which modality(*image* or *text*) is used to generate the embedding. 
+
+<br />
+
+
+
+## Interface
+
+An image-text embedding operator takes a [towhee image](link/to/towhee/image/api/doc) or string as input and generate an embedding in ndarray.
+
+
+**Parameters:**
+
+​	***data:*** *towhee.types.Image (a sub-class of numpy.ndarray)*  or *str*
+
+​  The data (image or text based on specified modality) to generate embedding.	
+
+
+
+**Returns:** *numpy.ndarray*
+
+​   The data embedding extracted by model.
