The theory of histogram modification of continuous real-valued pictures is developed. It is shown that the transformation of gray levels taking a pictures histogram to a desired histogram is unique under the constraint that the transformation be monotonic increasing. Algorithms for implementing this solution on digital pictures are discussed Contemporary Approaches to the Histogram Modification Based Data Hiding Techniques. By Yildiray Yalman, Feyzi Akar and Ismail Erturk. Submitted: June 16th 2011 Reviewed: September 23rd 2011 Published: November 7th 2012. DOI: 10.5772/3829 The histogram modification process can be considered to be a monotonic point transformation gd = T{fc} for which the input amplitude variable f1 < fc < fC is mapped into an output variable g1 < gd < gD such that the output probability distribution PR{gd = bd} follows some desired form for a given input probability distribution PR{fc = ac} where. The histogram modification strategy: (a) the original histogram and (b) the histogram shifting: shift bins larger than 0 rightward (orange bins). (c) Secret data embedding: embed secret data 0 by keeping the difference of the pixel value not changed (blue bin) and embed secret data 1 by changing the difference of the pixel value from 0 to 1 (red bin)

required to perform this modification is extracted from statistics of the observed sensor outputs. 2. A SIMPLE METHOD FOR LINEAR TRANSDUCERS If the image sensors are linear and time invariant, a simple method can be used to reduce striping. The sensor output, x', can be written as a function of the scene radiance, x, as follows: x' = f(x) = a + b-x The Histogram Modification Framework (HMF) focuses on minimizing a cost function to get the target histogram.

The whole process consists of two parts, namely, difference histogram generation and difference histogram modification. (1) Difference Histogram Generation

A cumulative histogram is a mapping that counts the cumulative number of observations in all of the bins up to the specified bin. That is, the cumulative histogram Mi of a histogram mj is defined as: Number of bins and width There is no best number of bins, and different bin sizes can reveal different features of the data In this paper, the method based on the 2D histogram modification is proposed to perform image CE and RDH simultaneously. In particular, a preprocessing strategy is developed to merge the adjacent bins in 2D histogram to prevent the overflow and underflow of the pixel values due to HE Histogram equalization cannot be applied separately to the Red, Green and Blue components of the image as it leads to dramatic changes in the image's color balance. However, if the image is first converted to another color space, like HSL/HSV color space, then the algorithm can be applied to the luminance or value channel without resulting in changes to the hue and saturation of the image

Histogram Modification Techniques

Examples of such methods include adaptive histogram equalization, contrast limiting adaptive histogram equalization or CLAHE, multipeak histogram equalization (MPHE), and multipurpose beta optimized bihistogram equalization (MBOBHE). The goal of these methods, especially MBOBHE, is to improve the contrast without producing brightness mean-shift and detail loss artifacts by modifying the HE algorithm Histogram Equalization is an image processing technique that adjusts the contrast of an image by using its histogram. To enhance the image's contrast, it spreads out the most frequent pixel. Abstract: Among various techniques of reversible data hiding (RDH), histogram modification has been mostly investigated and used in practice. Recently, a new histogram modification technique, namely, multiple histograms modification (MHM) has been proposed and received the increasing attentions. By MHM, multiple histograms can be modified. شرح خاص للطالب : على محمد احمدطالب بجامعة مودرن اكاديمى لتكنولوجيا المعلومات وعلوم الكمبيوترModern Academy for. Recently, with the deep understanding on RDH and continuous development on computing ability, the data embedding on the image can be optimized in a more detailed and skillful way. Li et al. proposed a multiple histograms modification (MHM) based RDH method. They decomposed the entire prediction-error histogram into 16 equal-sized histograms through the complexity measurement

Contemporary Approaches to the Histogram Modification

Some of the most basic tools in image processing, like median filtering and histogram equalization, are still among the most powerful. We will describe these and provide a modern interpretation of these basic tools. Students will then become familiar with simple and still popular approaches View Academics in Histogram Modification on Academia.edu Histogram Equalization. Histogram equalization is used to enhance contrast. It is not necessary that contrast will always be increase in this. There may be some cases were histogram equalization can be worse. In that cases the contrast is decreased. Lets start histogram equalization by taking this image below as a simple image

In fact, Histogram equalization is also can be taken as histogram matching, since we modify the histogram of an input image to be similar to the normal distribution. In order to match the histogram of images A and B, we need to first equalize the histogram of both images. Then, we need to map each pixel of A to B using the equalized histograms • Adaptive histogram modification Yao Wang, NYU-Poly EL5123: Contrast Enhancement 2. What is Contrast Enhancement - depends on the histogram of the original image h A(f) and the desired histogram of the transformed imageand the desired histogram of the transformed image h B(f) Histograms help detect image acquisition issues Problems with image can be identified on histogram Over and under exposure Brightness Contrast Dynamic Range Point operations can be used to alter histogram. E.g Addition Multiplication Exp and Log Intensity Windowing (Contrast Modification Histogram Types. The histogram can be classified into different types based on the frequency distribution of the data. There are different types of distributions, such as normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distributions, heart cut distribution, and so on Histogram Equalization of a Black and White Image is fairly straight forward, and can be done using the hist_equalized function of OpenCV.

This function takes in a vector of values for which the histogram is plotted. Let us use the built-in dataset airquality which has Daily air quality measurements in New York, May to September 1973. -R documentation The formula for stretching the histogram of the image to increase the contrast is. The formula requires finding the minimum and maximum pixel intensity multiply by levels of gray. In our case the image is 8bpp, so levels of gray are 256. The minimum value is 0 and the maximum value is 225. So the formula in our case is The embedding performance was good in terms of image quality and payload. Krishna et al. [10] proposed an efficient extension of the histogram modification technique by considering the differences between adjacent pixels instead of using simple pixel value. They used binary tree that predetermines the multiple peak points used to embed messages
