A DWT-SVD based robust digital watermarking for medical image security
TL;DR: In this article, a blind watermarking approach for medical image protection is proposed, which consists of the Electronic Patient Record and the image acquisition data, and the watermark is then integrated into the least significant bits of the S component obtained by combining the parity of the successive coefficients.
Journal ArticleDOI
Robust SVD-based schemes for medical image watermarking
TL;DR: This innovative approach consists precisely of carefully inserting hospital signature information and patient data into the medical image to protect medical images and ensures information integrity, patient confidentiality when sharing data, and robustness to several conventional attacks.
Journal ArticleDOI
A lossless DWT-SVD domain watermarking for medical information security
TL;DR: In this article, a DWT decomposition is appropriately applied to the image which allows a remarkably satisfactory adjustment during the insertion, which ideally allows retaining the maximum energy of the used image in a guaranteed minimum of singular values.
Journal ArticleDOI
A value parity combination based scheme for retinal images watermarking
TL;DR: In this article, two watermarking schemes for retinal image protection are proposed, which are implemented in the three insertion domains: spatial, frequency and multi-resolution domain, respectively, for the spatial domain, the watermark will be integrated into the R, G and B values of the image.
Proceedings ArticleDOI
Facial Expression Recognition Using Neural Network Trained with Zernike Moments
TL;DR: A back propagation neural network was trained to distinguish between the seven emotion's states of a presented face and the neutral one in this work to perform facial expression recognition.
