tencentarc/gfpgan: Blurry photos can be a frustrating problem for photographers of all levels. Whether you’re using a high-end camera or smartphone, it’s easy to end up with a blurry photo that ruins an otherwise great shot. There are several common causes of blurry photos, including camera shake, slow shutter speed, and incorrect focus. One of the most common reasons for blurry images is camera shake. Blurring during photography is caused by motion of the camera itself. This occurs most often when the shutter speed is too slow. Sometimes you think you took the perfect shot, only to have it turn out fuzzy because you accidentally shake the camera.
Photographers can be very upset when they take blurry pictures of “the moment,” because these memories are often irreplaceable. When trying to take pictures of things that move quickly, photographers find it hard to get a clear, sharp image. Afterall everything is not in our hands and control. Not everything is in our hands and under our control, after all. But that could change now. With AI progressing to a whole new level, you can now easily unblur the image.
AI : How it helps?
Artificial intelligence (AI) can be used to help restore blurry images by analyzing the image and attempting to recover lost details. This is how it works:
- Deblurring Algorithms: AI algorithms analyze the image’s patterns and features using mathematical models. They use this information to generate an estimate of the original, unblurred image. To produce the best possible result, the algorithms take into account the specific blur type (e.g., motion blur, out-of-focus blur, etc.).
- Neural Networks: AI neural networks are machine learning models that can be trained to identify patterns in images. By taking a blurry image as input and producing a sharp, clear image as output, these networks can be used to deblur images.
- Super-Resolution: AI can also be used to boost the resolution of blurry images, effectively restoring lost details. This technique, known as super-resolution, analyses the image and generates a higher-resolution version of the original image using AI algorithms.
Whether using deblurring algorithms, neural networks, or super-resolution techniques, AI can help restore the details lost due to blur, resulting in clearer, sharper images. There are several tools available online to assist you with this. Tencentarc/gfpgan is one such tool that can assist you in unblurring images with AI.
What is Tencentarc & What is Replicate?
Before going to reveal more about tencentarc, you have to know about replicate. Replicate is a cloud-based platform that allows users to run open-source machine learning models. It includes a user-friendly interface for deploying and running pre-trained models, as well as tools for managing and monitoring the models once they are in use. Users can use Replicate to run models for tasks like image classification, object detection, and natural language processing, among others. TensorFlow, PyTorch, and scikit-learn are among the popular machine learning frameworks available on the platform. This enables users to select the framework and model that best meets their needs while ignoring the underlying infrastructure.
TencentARC/GFP-GAN is a deep learning model for generating images. It works on GAN. Generative Adversarial Networks (GANs) are a type of deep learning model that are used to generate new data that is similar to a given training dataset. In a GAN, the generator network generates new images, while the discriminator network evaluates the generated images. It determines whether they are sufficiently similar to the training images. The discriminator and generator networks are adversarial trained, with the generator attempting to produce images that are indistinguishable from the training images and the discriminator attempting to accurately identify generated images. The generator can learn to generate high-quality images.
This tool can unblur images to a greater extent, and the results are incredible. I experimented with various blurred images and was not disappointed at all. The tool works like a charm and unblur every image you threw at it. All you need to do is:
How to Use tencentarc/gfpgan
- Go to the above link .
- You can upload your images via Webcam or through your File Manager.
- Select the version to v1.4 (Default)
- After that, select scale and give it a value between 1 to 10. (Rescaling factor refers to a scalar value that is used to change the size or scale of an object or image). For best results give 7.
- Submit your image.
Voila, your image will be unblurred within seconds. Here are some results I’ve tested and have a look at the results. They are quite astonishing.
I’ve tested about 12 images and the tool was able to perfectly restore about 8 of them. However, as we all know, AI is still in its early stages and will take a long time to improve. The same holds true for this tool. Sometimes, this tool is changing facial features all at once. The tool has totally changed the features of Justin, Jay-z & Kim Kardashian. This is the drawback that I observed while using it. Just look at the image below.
