Super resolution encompases a set of algorithms and techniques used to enhance, increase, and upsample the resolution of an input image. We’ll wrap up this tutorial with a discussion of our results.

How specialized deep learning architectures can help us achieve super resolution in real-timeįrom there, I’ll show you how to implement OpenCV super resolution with both:.Why we can’t use simple nearest neighbor, linear, or bicubic interpolation to substantially increase the resolution of images.

In the first part of this tutorial, we will discuss: Looking for the source code to this post? Jump Right To The Downloads Section OpenCV Super Resolution with Deep Learning To learn how to use OpenCV for deep learning-based super resolution, just keep reading. The function requires a bit of explanation to use, so I decided to author a tutorial on it that way everyone can learn how to use OpenCV’s super resolution functionality.īy the end of this tutorial, you’ll be able to perform super resolution with OpenCV in both images and real-time video streams! However, OpenCV’s super resolution functionality is actually “hidden” in a submodule named in dnn_superres in an obscure function called DnnSuperResImpl_create. Pre-trained (meaning you don’t have to train them yourself on a dataset).You’re in luck, Hisham - there are super resolution deep neural networks that are both:

If you have any suggestions, that would be a big help.” It was super helpful, thank you.Īre there any pre-trained super resolution models compatible with OpenCV’s dnn module? “Hi Adrian, I read your Deep Learning for Computer Vision with Python book and went through your super resolution implementation with Keras and TensorFlow.
