Access streamlit uploaded image in opencv

How do I open image in opencv. I have this code which gets uploaded image and displays it on streamlit:

uploaded_file = st.file_uploader("Choose a image file")
if uploaded_file is not None:
	image = uploaded_file.read()
	img = st.image(image, caption='Sunrise by the mountains', use_column_width=True)

My question is I want to read and save this uploaded file using:

import cv2
im1=cv2.imread(image)
im2=cv2.imwrite('out.jpg', im1)

How can I achieve this ?

Nice! I was just about to post an example too 😄

For posterity, here’s the way I did it:

import cv2
import numpy as np
import streamlit as st

uploaded_file = st.file_uploader("Choose a image file", type="jpg")

if uploaded_file is not None:
    # Convert the file to an opencv image.
    file_bytes = np.asarray(bytearray(uploaded_file.read()), dtype=np.uint8)
    opencv_image = cv2.imdecode(file_bytes, 1)

    # Now do something with the image! For example, let's display it:
    st.image(opencv_image, channels="BGR")

uploaded_file = st.file_uploader("Upload Image")
image = Image.open(uploaded_file)
st.image(image, caption='Input', use_column_width=True)
img_array = np.array(image)
cv2.imwrite('out.jpg', cv2.cvtColor(img_array, cv2.COLOR_RGB2BGR))
