IMAGE ENHANCEMENT TECHNIQUES USING FREQUENCY DOMAIN FILTERING
Image Enhancement?
It is the process of making an image more pleasable than the original image.
Why needed?
Noise introduced in to the image, out-of focus , atmospheric conditions, latency of imaging hardware.
Applications
Medical imaging.
Satellite imaging.
Material testing in industries.
Fingerprint identification.
Printing and publishing industry.
Conclusion
Thus, image enhancement techniques in frequency domain improves the desired features of an image based on the requirements of the applications.
