Shark-Image-Extraction

🦈🔬Underwater Shark Image Extraction Without Machine Learning

Prerequisites

pip3 install opencv-contrib-python numpy

Algorithm:

1. Create multiple images from a combination of different channels and color spaces
2. Create an image with a detailed view of the shark in grayscale and color
3. Create a binary mask that can identify the shark and part of the image we don't want
4. Create a 2nd binary mask that can identify the shark and a different part of the image we don't want
5. Combine and clean the two masks to get a rough outline of the shark
6. Fill the outline/edges so that it can actually be used as a mask
7. Use the mask to extract only the shark from the detailed image
8. Crop the image to only contain the shark using the mask as a guide
9. Replace the background color with white
10. Display both a Grayscale and Color version of the shark
