Blur Invariant Block based Copy-Move Forgery Detection Technique using FWHT Features
Proceedings of the International Conference on Watermarking and Image Processing, 2017Copy-move forgery detection has become a prominent research area. In this paper, an efficient block based copy-move forgery detection algorithm based on Fast Walsh Hadamard Transform is presented with an objective to reduce processing time in identifying the duplicated regions in an image.

Digital Watermarking Algorithm Based on CCC - FWHT Technique
International Journal of Advancements in Computing Technology, 2012This paper proposes a watermarking algorithm to embed a watermark generated through Complete complementary code method into the original image by using Fast Walsh Hadamard Transform (FWHT) technique. Two valued kernels of Hadamard transformation cause smaller image information change during embedding compared to other transform domains. Spread spectrum

A MULTIPLE AND ROBUST IMAGE WATERMARKING APPROACH BASED ON LWT AND FWHT FOR MEDICAL DATA SECURITY
Journal of Mechanics in Medicine and Biology, 2022In the last years, the internet and multimedia technologies are widely used to exchange medical images and practicing telemedicine; which exposes this data to various illegitimate attacks due to their sensitivity. For this reason, many researchers work to afford a proper security and an efficient protection during the transmission. In this context, we

In this research a new approach is introduced for detecting and classifying faults in a Thyristor-Controlled Series Capacitor (TCSC) compensated power system. Our proposed scheme utilizes both the Fast Walsh Hadamard Transform (FWHT) and machine learning algorithms. The FWHT is employed to extract fault features from current data obtained from the TCSC

Fault Detection for the Suspension System of Maglev Train Based on FWHT and SVDD
2019 IEEE 8th Data Driven Control and Learning Systems Conference (DDCLS), 2019In order to achieve fault detection of the suspension system, a fault detection method based on support vector data description is proposed. In the proposed method, the moving time window is used to extract the healthy samples, and the fast Walsh-Hadamard transform and the median filter are used to extract features and filter.
