In this article, a new reversible data hiding method using most significant bits and center shifting technique in dual images is proposed. The proposed aims to securely hide high-capacity secret data. Instead of directly embedding the data, calculates values with (n + 1) n cover image pixel values. Thus, it impossible extract without obtaining original image. Also, process performed minimize me...

There have been many published studies aiming to identify temporal changes in river flow time series, most of which use monotonic trend tests such as the Mann–Kendall test. Although robust to both the distribution of the data and incomplete records, these tests have important limitations and provide no information as to whether a change in variability mirrors a change in magnitude. This study d...

Reversible data hiding (RDH) techniques recover the original cover image after extraction. Thus, they have gained popularity in e-healthcare, law forensics, and military applications. However, histogram shifting using a reversible embedding technique suffers from low capacity high variability. This work proposes which distribution obtained determines pixels that attain peak or zero distribution...

The idea of Fixation introduced a direct method for general recovery of shape and motion from images without using either feature correspondence or optical flow [1,2]. There are some parameters which have important effects on the performance of fixation method. However, the theory of fixation does not say anything about the autonomous and correct choice of those parameters. This paper presents ...
