What do you mean by oversampling?

Oversampling is a technology in the field of image processing, and its purpose is to improve the image quality by increasing the resolution and details of the image. It is usually used in digital photography, film production, television production and computer graphics.

Super-sampling technology uses algorithms to improve the resolution of images, thus making the details of images clearer and finer. This technique is based on a complex data reasoning model, which relies on similar pixels in the image to calculate the value of missing pixels. The application of oversampling technology can not only improve the clarity of images, but also be used for noise reduction and antialiasing in digital photography.

Over-sampling can use many techniques and algorithms, among which bilinear interpolation, bicubic interpolation and nearest neighbor interpolation are the most commonly used. These algorithms can calculate the missing image pixels on the computer, thus improving the image quality. In addition, oversampling technology can also be applied to anti-aliasing and edge detection in computer graphics to improve the realism and detail expression of images.
