This demo explores KoCLIP's use case as a Korean image search engine. We pre-computed embeddings of 5000 images from [MSCOCO](https://cocodataset.org/#home) 2017 validation using KoCLIP's ViT backbone. Then, given a text query from the user, these image embeddings are ranked based on cosine similarity. Top matches are displayed below.
Example Queries: 컴퓨터하는 고양이 (Cat playing on a computer), 길 위에서 달리는 자동차 (Car on the road)
query = st.text_input("한글 질문을 적어주세요 (Korean Text Query) :", value="컴퓨터하는 고양이")
if st.button("질문 (Query)"):
with st.spinner("Computing..."):
proc = processor(
text=[query], images=None, return_tensors="jax", padding=True
vec = np.asarray(model.get_text_features(**proc))
ids, dists = index.knnQuery(vec, k=10)
result_files = map(lambda id: files[id], ids)
result_imgs, result_captions = [], []
for file, dist in zip(result_files, dists):
result_imgs.append(plt.imread(os.path.join(images_directory, file)))
result_captions.append("Score: {:.3f}".format(1.0 - dist))
st.image(result_imgs[:3], caption=result_captions[:3], width=200)
