“…Digital watermarking is the act of hiding information in multimedia data, such as image, video or audio, for content protection or authentication [705]. FPGAs in digital watermarking have been used for real time watermarking detection in video [706,707], Discrete Cosine Transform (DCT) based digital image watermarking [708][709][710] and Discrete Wavelet Transform (DWT) based digital image/audio watermarking [555,711,712]. Image enhancement is used "to improve interpretability or perception of info available within the images, making it suitable for human vision, as well as to provide improved input to the other automated image processing techniques" [713].…”

Field Programmable Gate Array (FPGA) is a general purpose programmable logic device that can be configured by a customer after manufacturing to perform from a simple logic gate operations to complex systems on chip or even artificial intelligence systems. Scientific publications related to FPGA started in 1992 and, up to now, we found more than 70,000 documents in the two leading scientific databases (Scopus and Clarivative Web of Science). These publications show the vast range of applications based on FPGAs, from the new mechanism that enables the magnetic suspension system for the kilogram redefinition, to the Mars rovers’ navigation systems. This paper reviews the top FPGAs’ applications by a scientometric analysis in ScientoPy, covering publications related to FPGAs from 1992 to 2018. Here we found the top 150 applications that we divided into the following categories: digital control, communication interfaces, networking, computer security, cryptography techniques, machine learning, digital signal processing, image and video processing, big data, computer algorithms and other applications. Also, we present an evolution and trend analysis of the related applications.

“…The algorithm suffers from blocking artifacts which affects the visual quality of watermarked video. Wessam et al [9] proposed FPGA implementation of video watermarking where pseudo random watermark is inserted in low frequency components of DCT. The technique is used to embed an invisible watermark in each frame of video.…”

“…It was noted that all these algorithms/implementations are either based on uncompressed domain or requires huge complex computation. The limitations of the algorithms restrict the real time integration with H.264 standard [4,9,17,25,28,33,37]. Some compressed domain algorithms have their own application domain [29,35].…”

Digital video watermarking has drawn the attention towards authentication and proof of ownership. Uncompressed domain watermarking has flourished over the years and related algorithms have been implemented on the software platform. Software watermarking algorithms work offline where videos are captured through device and embedding algorithms run on a PC that is used to embed the watermark in the original video content. It doesn't suffice real time requirements because of the delay that takes place between capturing and embedding the watermark. This delay involvement is more prone to attacks. Thus, it is essential to develop the system where the watermark gets embedded at the same time when video is being captured. In this paper, an efficient watermark embedding process has been portrayed which is suited to H.264/AVC standard. The proposed algorithm introduces the concept of scene change detection based on Integer Discrete Cosine Transform (Integer-DCT) using scene change detection. The different frames of a scene are embedded with different bit planes of the same watermark in order to improve the performance against temporal attacks. The algorithm is validated on the MATLAB platform and is prototyped on FPGA to show its feasibility for real-time application.
