Understanding Image Resolution
Before we dive into the methods for upscaling images, it’s essential to understand the basics of image resolution. Image resolution refers to the number of pixels that make up an image. The more pixels an image has, the higher its resolution and the clearer it will appear. There are two main types of image resolution:
Pixels Per Inch (PPI)
Pixels Per Inch (PPI) measures the number of pixels per inch of an image. A higher PPI indicates a higher resolution image. For example, an image with a PPI of 300 is considered high-resolution, while an image with a PPI of 72 is considered low-resolution.
Dots Per Inch (DPI)
Dots Per Inch (DPI) measures the number of dots per inch of an image. DPI is commonly used to describe the resolution of printed images. A higher DPI indicates a higher resolution image.
