The imaging technique that attempts to fix the effects of upsampling or downsampling an image's resolution is anti-aliasing. Anti-aliasing helps reduce jagged edges or stair-step effects that can occur when an image is resized or displayed at a lower resolution.
Here's how anti-aliasing works:
1. When an image is downsampled (reduced in size), anti-aliasing techniques are used to smooth out the edges and prevent aliasing artifacts.
2. Similarly, when an image is upsampled (enlarged), anti-aliasing helps in creating a smoother appearance by blending pixels together and reducing pixelation.
By applying anti-aliasing, the quality of the image is improved, and the visual artifacts caused by upsampling or downsampling are minimized, resulting in a more visually appealing and realistic image representation.
