Invertible Data Embedding By Histogram Modification and Contrast Enhancement
نویسندگان
چکیده
The main aim is to enhance the contrast of a host image by Reversible data hiding algorithm and to improve its visual quality. The highest two bins in the histogram are selected for data embedding so that histogram equalization can be performed by repeating the process. The Reversible data hiding algorithm is used for better preserving the visual quality of contrast enhanced image with increased efficiency. Further, the evaluation result shows that the visual quality can be preserved and also it can be applied to medical and satellite images for better visibility.

Density-Based Histogram Partitioning and Local Equalization for Contrast Enhancement of Images
Histogram Equalization technique is one of the basic methods in image contrast enhancement. Using this method, in the case of images with uniform gray levels (with narrow histogram), causes loss of image detail and the natural look of the image. To overcome this problem and to have a better image contrast enhancement, a new two-step method was proposed. In the first step, the image histogram is...
متن کاملA General Framework for 1-D Histogram-baesd Image Contrast Enhancement
In this paper, a general framework for image contrast enhancement algorithm based on an optimization problem is presented. Through this optimization, the intensities can be better distributed. The algorithm is based on the facts that the histogram of the enhanced image is close to the input image histogram and uniform distribution, simultaneously. Based on this fact, we obtain a closed form opt...
متن کاملLow-complexity Histogram Modification Algorithm for Contrast Enhancement
Histogram equalization is widely used in different ways to perform contrast enhancement in images. In this paper, a new Histogram modification algorithm is proposed for contrast enhancement of images. Histogram Equalization (HE) is one of the most popular technique used for digital image enhancement, but it is not suitable to be implemented directly in consumer electronics, such as television, ...
متن کاملReversible Data Hiding Using Contrast Enhancement Approach
Reverse Data Hiding is a technique used to hide the object's data details. This technique is used to ensure the security and to protect the integrity of the object from any modification by preventing intended and unintended changes. Digital watermarking is a key ingredient to multimedia protection. However, most existing techniques distort the original content as a side effect of image protecti...
متن کاملLossless Data Hiding Based on Integer Wavelet Transform
This paper proposes a novel data hiding algorithm having large data hiding rate based on integer wavelet transform, which can recover original image without any distortion from the marked image after the hidden data have been extracted. This algorithm hides the data and the overhead data representing the bookkeeping information into a middle bit-plane of the integer wavelet coefficients in high...
