Sketch Application using Streamlit

Web App to convert image in to sketch image

Packages:

• streamlit – pip install streamlit
• numpy- pip install numpy
• opencv-python – pip install opencv-python
• Pillow – pip install Pillow

Logic

• Convert the color image to grayscale – gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
• Invert the grayscale image to get a negative – imagem = cv2.bitwise_not(imagem)
• Apply a Gaussian blur to the negative from step 2 – blur = cv.GaussianBlur()
• Blend the grayscale image from step 1 with the blurred negative from step 3 using a color dodge – dodgeV2(mg_gray, img_blur)
