What does image upgrade mean?
When looking at a poor quality image, it is most likely due to the low resolution, the image has fewer pixels leaving insufficient information to represent it. Upscaling is the process of increasing the resolution of an image, thereby improving the quality of the image.
Traditional image sharpening methods take the average value of the four closest pixels to determine the color of a new pixel in the upgraded image. Some methods also use a specific formula to calculate the weighted average of 16 neighboring pixels to create the color of new pixels. However, AI can upscale images using Super Resolution Techniques.
AI tools contain models trained on large data sets. This helps it evaluate existing pixels, understand patterns, and predict additional pixels to improve quality. AI models have significantly improved the way images are upscaled, and below are AI tools that can be used for free to improve image quality.
