Three Free Methods of Image Upscaling

Image upscaling refers to the process of enhancing the resolution of an image without losing its quality. This can be done using several techniques such as interpolation, bicubic interpolation, and nearest neighbor interpolation. These techniques involve analyzing pixels of a lower resolution image and estimating pixels of a higher resolution image based on the pixels of the lower resolution image. This enhances the pixels of the lower resolution image and increases its resolution. Upscaling can also involve enhancing color and contrast of an image. This can be done using several techniques such as histogram equalization and color correction.
