Abstract
In this paper, we present the adaptive bilateral filter (ABF) for sharpness enhancement and noise removal. The ABF sharpens an image by increasing the slope of the edges without producing overshoot or undershoot. It is an approach to sharpness enhancement that is fundamentally different from the unsharp mask (USM). This new approach to slope restoration also differs significantl ....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

ENHANCEMENT OF VEHICLE STABILITY BY ACTIVE GEOMETRY
CONTROL SUSPENSION SYSTEM
1. INTRODUCTION
In recent years, there has been increased need to develop high-performance suspension for high-power engines ,especially active chassis control systems have been developed and mass-produced in the market to compromise vehicle ride and handling performance simultaneously,
The conventional active chassis control systems control the vehicle phenomenon such as body roll, yaw, and pitch using hydraulic actuators w ....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

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

Common mode rejection ratio (CMRR) is important performance parameter of any difference amplifier. It is the ratio of the differential gain to the common-mode gain, generally expressed in dB. It signifies the ability of an opamp to reject common mode signal, the signal which appears simultaneously at both its input terminals. The CMRR is of great importance when it comes to noise rejection. For applications involving high CMRR, instrumentation amplifiers consisting of three opamps are generally used. It has a major disadvantage that the value o ....etc

Abstract


This work presents a novel algorithm using color contrast enhancement and lacuna texture synthesis is proposed for the virtual restoration of ancient Chinese paintings. Color contrast enhancement based on saturation and de-saturation is performed in the u'v'Y color space, to change the saturation value in the chromaticity diagram, and adaptive histogram equalization then is adopted to adjust the luminance component. Additionally, this work presents a new patching method using the Markov Random Field (MRF) model of texture synthes ....etc
