Image enhancement is implemented in spatial domain approach that operates directly to the pixels and frequency domain approach that operates through Fourier transform of an image. Image enhancement techniques in

Image fusionDual optical pathIn this paper, we propose a novel molten image enhancement and fusion method based on image decomposition in frequency domain. The algorithm combines the guided filter to maintain the original edge and details and to make it show a more permeable visual effect. ...

Frequency domain transform – [46–56] High efficiency. Multi-resolution Expression. Artifacts like over/under enhancement. Color correction – [57–65] Effective to color shifting. May fail when image is of little color variance. Image restoration based ASM based Prior based [66,67,67–74] Ef...
In this work, we discussed good measures for palmprint image quality assessment using the spatial and frequency domain enhancement techniques with the least errors. This makes it more appropriate for a specified task. Multiple quantitative image quality metrics [4,55–57] (Table 2) such as Contras...

Basically it says you have tosampleat least attwice the max frequencyof your input signals. Otherwise you'll get poor results, likelossy and aliasing. That "twice" inNyquist theoremcomes from the "raster" in thefrequency domain. Oversamplingdoesn't mean you get the same perfect answer. ...
