Abstract:Screen content video coding has become an emerging research topic with the spread of applications such as cloud gaming, screen/desktop virtualization, and mobile or external display interfacing. Screen content videos have different features compared to conventional camcorder-captured scenes. In this work, a novel low bit-depth representation-based motion estimation approach is proposed to exploit screen content specific features to improve coding efficiency. The proposed approach is based on an adaptive select… Show more
“…The C2BT reduces the computational complexity of concealed text frames to 2-bit representations. The results of the simulation show that the C2BT algorithm increases the accuracy of the text by 0.35 dB for 2BT-BME and 0.28 dB for C1BT-Block Motion Estimation (BME), respectively [12]. A proposed fast motion estimation with data hiding based on the enhanced forced one-bit transform has been proposed [13].…”
The scope of this research is to overcome the computational complexity of the methods for hiding messages inside video frames using various advanced search procedures. For this purpose, the optimal binary coding scheme with low-complexity frame adjustment has been implemented for wireless video transmission applications. To minimize the computational complexity of concealing the existence of messages and the ability to accurately extract them, the Improved Search Pattern with Discrete Wavelet Transform Based Phase Correlation (ISP-DWT-PC) was computed. The approach has also been used to improve the speed of the hidden data retrieval reliably using a simpler search pattern. This paper emphasizes computer forensics procedures, which acts as a tool for data security, reliability, and authentication in video steganography applications works. The results that have been achieved is surpassed the traditional methods in terms of PSNR, MSE, SSIM, Accuracy, surpassed, sensitivity and specificity.
