Background: With today’s emerging world of technology, fusion is the key factor in every field, especially in the field of medical and remote sensing. By fusing two or more images, we get necessary useful data in a particular fused image. So it is the best technique to remove noise data from those images.
Methods: Noise or Blurring are those unwanted data that affects the quality of an image in terms of clarity. There are numerous methods for image fusion that can be used to eliminate noise or blurring that gives best results in the form of the fused image.
Conclusion: In this paper, diverse techniques have been reviewed, studied and compared to discover the limitations of multiple image fusion techniques.
