The Curvelet Transform

open access: yesIEEE Signal Processing Magazine, 2010
Multiresolution methods are deeply related to image processing, biological and computer vision, and scientific computing. The curvelet transform is a multiscale directional transform that allows an almost optimal nonadaptive sparse representation of objects with edges.

Improved ECG Watermarking Technique Using Curvelet Transform

open access: yesSensors, 2020
Hiding data in electrocardiogram signals are a big challenge due to the embedded information that can hamper the accuracy of disease detection. On the other hand, hiding data into ECG signals provides more security for, and authenticity of, the patient’s
