In today’s digital age, images are prevalent across various platforms, whether for personal use, marketing campaigns, or social media. However, many images come with watermarks, which can obscure the content and diminish its visual appeal. The ability to remove watermarks easily is a sought-after skill, especially for those who work with images regularly. Let’s explore how to effectively remove watermarks using a machine-learning approach found in the GitHub repository zuruoke/watermark-removal.

The Process of Watermark Removal
Watermarks serve as a protective measure for photographers and artists, ensuring that their work is credited and not misused. They can be intrusive, often detracting from the overall aesthetic of an image. The process of watermark removal has evolved significantly over the years, especially with the advent of machine learning and artificial intelligence. Traditional methods often involved manual editing techniques in software like Adobe Photoshop, requiring significant skill and time. However, machine learning algorithms can automate and enhance this process, making it faster and more efficient.
Zuruoke/Watermark-Removal
The GitHub project zuruoke/watermark-removal by Chimzuruoke Okafor utilizes image inpainting techniques based on advanced algorithms. These methods draw inspiration from notable papers like “Generative Image Inpainting with Contextual Attention” and “Free-Form Image Inpainting with Gated Convolution.” By using these techniques, the project aims to create results that are indistinguishable from the original images without watermarks. Note that this approach is only limited to removing watermarks from iStock images.

How to Get Started With Watermark Removal (GitHub)
To remove watermarks from your images using this approach, you’ll first need to set up the environment. The process is straightforward, especially for those familiar with using GitHub and Google Colab. Here’s a step-by-step guide:
1. Open Google Colab
Go to https://colab.research.google.com/. Click on “New Notebook” or “File”>”New notebook”
2. Clone the Repository
Start by cloning the repository to your local machine or your Google Colab environment. You can do this with the command:
!git clone https://github.com/zuruoke/watermark-removal
This command downloads the entire project repository to your Colab environment.
3. Change Directory
!cd watermark-removal
4. Downgrade TensorFlow
!pip install tensorflow==1.15.0
This installs the specific TensorFlow version required by the project.
5. Install Neural Gym
!pip install git+https://github.com/JiahuiYu/neuralgym
This installs the neural network toolkit used in the project.
6. Download Model
The instructions mention downloading model directories
You’ll need to go to the provided download link. Download the model files. Upload them to your Colab notebook model/
directory. Also, rename checkpoint.txt to checkpoint.
7. Run Watermark Removal
!python main.py --image path-to-input-image --output path-to-output-image --checkpoint_dir model/ --watermark_type istock
From above:
- Replace path-to-input-image with the actual path to your watermarked image
- Replace path-to-output-image with where you want to save the watermark-free image
Make sure you’ve uploaded your input image to the Colab environment first. The –watermark_type istock suggests this is specifically for iStock watermarks.
Advantages of Using Machine Learning for Watermark Removal
One of the standout features of using machine learning techniques to remove watermarks from images is the level of sophistication involved. Unlike traditional methods, which often leave traces of editing, machine learning models can analyze the surrounding pixels and create a natural-looking output. This capability is particularly advantageous for images where the watermark overlaps with intricate details or colours. Additionally, the process is significantly faster than manual editing. While it may take hours to achieve a satisfactory result using conventional methods, machine learning can accomplish this in minutes. This efficiency is crucial for professionals and businesses that require high-quality images in a timely manner.
Ethical Considerations in Watermark Removal
While the technology for removing watermarks is readily available, it is essential to approach this capability with a sense of responsibility. Removing watermarks from images that you do not own or have rights to can lead to legal repercussions and undermine the efforts of original creators. Always ensure that you have permission to edit or use images in this way. Moreover, consider the context in which you are using the images. For personal projects, watermark removal may be acceptable if done ethically. However, using such images for commercial purposes without proper rights can lead to serious ethical dilemmas.
Last But Not Least
The rise of AI-powered image inpainting has revolutionized the way we approach watermark removal, enabling indistinguishable results that restore the original visual integrity of images. By using this approach, users can transform a once labour-intensive task into an automated, efficient, and highly effective process.
