New Stenographic method to hiding information in digital image [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2017
Steganography is the art of hiding information in different cover media, then sending & displaying the hidden information especially in public places, Therefore, different methods have been proposed so far for hiding information. In this paper new method

Transform domain distributed video coding using larger transform blocks [PDF]

, 2017
Distributed Video Coding (DVC) displays promising performance at low spatial resolutions but begins to struggle as the resolution increases. One of the limiting aspects is its 4x4 block size of Discrete Cosine Transform (DCT) which is often impractical ...

Hybrid hiding in multimedia files [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2012
The principle of hybrid information hiding represented by process of information hiding  message (multimedia files) embedded inside another message which is depended on hiding a certain media in another media using different domains (special domain ...

Multiple description video coding based on zero padding [PDF]

, 2004
This paper proposes a simple multiple description video coding approach based on zero padding theory. It is completely based on pre- and post-processing, which require no modifications to the source codec.

Type-II/III DCT/DST algorithms with reduced number of arithmetic operations

, 2009
We present algorithms for the discrete cosine transform (DCT) and discrete sine transform (DST), of types II and III, that achieve a lower count of real multiplications and additions than previously published algorithms, without sacrificing numerical ...

Steerable Discrete Cosine Transform [PDF]

, 2017
In image compression, classical block-based separable transforms tend to be inefficient when image blocks contain arbitrarily shaped discontinuities. For this reason, transforms incorporating directional information are an appealing alternative.

NKCC1: A key regulator of glioblastoma progression

Molecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

FEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...
