Do you have a poor quality photos ?
Have a low resolution picture you wish was HD. I edit and review these images and make sure they are upscaled, denoised or sharpened to the best of the ability to ensure a High Definition image.
What is image denoising?
One of the fundamental challenges in the field of image processing and computer vision is image denoising, where the underlying goal is to estimate the original image by suppressing noise from a noise-contaminated version of the image.
