3 min readJan 8, 2023
Some form of image interpolation is always taking place when manipulating digital images — whether it’s resizing them to increase or decrease the total number of pixels, correcting for lens distortion, changing perspective, or rotating an image.
Rephrase Interpolation is an approximation that may result in image degradation each time it’s performed. The image may vary significantly depending on the interpolation algorithm used.
In this post, i will provide an overview of the diffrent interpolation algorithm that OpenCV uses
