Prelacrimal Recess‐Pterygoid Window Approach to the Sphenoidal Lateral Recess Skull Base Defects
World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 66-76, February 2026.ABSTRACT Objective The objectives of this study are: (1) to evaluate the prelacrimal recess‐pterygoid window approach (PLR‐PWA) for treating cerebrospinal fluid leaks and meningoencephaloceles (CSFLME) in the sphenoidal lateral recess (SLR). (2) To investigate the pneumatization of the SLR and its relationship with surrounding structures, including the

Digital Image Watermarking Using Ellipse Watermark
, 2017 From past few decades watermarking became very crucial for digital images being transmitted over network. All the time ownership and license are great issues if someone fetches the image sent by one without any ownership seal, i.e. watermark, and uses as his own image.

Watermarking Algorithms for 3D NURBS Graphic Data
EURASIP Journal on Advances in Signal Processing, 2004 Two watermarking algorithms for 3D nonuniform rational B-spline (NURBS) graphic data are proposed: one is appropriate for the steganography, and the other for watermarking.

Advances in Electrical and Computer Engineering, 2017 A novel secure and robust image watermarking technique for color images is presented in this paper. Besides robustness and imperceptibility (which are the most important requisites of any watermarking scheme), there are two other challenges a good ...
