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 ....etc

IMAGE ENHANCEMENT TECHNIQUES

SUBMITTED BY
INTRODUCTION
Image enhancement widely used in computer graphics.
It is the sub areas of image processing.
The principle objectives of image enhancement techniques is to process an image so that the result is more

suitable than the original image for a specific application .
METHODS FOR IMAGE ENHANCEMENT
Image enhancement techniques can be divided into two broad categories:

1.Spatial domain methods .
2 Frequency domain methods.
SPATIAL DOMAIN METHODS ....etc

Abstract
Extracting minutiae from fingerprint images is one of the most important steps in automatic fingerprint identification and classification. Minutiae are local discontinuities in the fingerprint pattern, mainly terminations and bifurcations. In this work we propose two methods for fingerprint image enhancement. The first one is carried out using local hist ....etc

A PAPER
ON
CHROMOSOME IMAGE ENHANCEMENT AND IDENTIFICATION

Presented By:
Mr. V. Subba Reddy,
ME (Digital Systems),
Abstract:-
Image processing has been used in almost all the areas such as remote sensing, military, biomedical, industrial applications. The world is growing more crowded all the time, with a fragile environment that needs protection. Natural resources are becoming increasingly precious and hard to find.
This paper is mainly focused on chromosome image enhancement and future extraction bas ....etc

INTRODUCTION
Image enhancement and edge detection are well known digital image signal processing applications that may require two-dimensional (2-D) filter-like computational solutions. These applications usually depend on computation intensive code sections, consisting of the repetition of sequences of operations. They are also characterized by the multi-dimensionality of the data involved. An effective technique in improving the computing performance of such applications has been the design and use of Application Specific ....etc
