Current concepts in the pathophysiology of glaucoma

Glaucoma, the second leading cause of blindness, is characterized by changes in the optic disc and visual field defects.The elevated intraocular pressure was considered the prime factor responsible for the glaucomatous optic neuropathy involving death of retinal ganglion cells and their axons.Extensive investigations into the pathophysiology of gla

IWT and RSA based asymmetric image encryption algorithm

An asymmetric image encryption algorithm Other switches based on integer wavelet transformation (IWT) and Rivest-Shamir-Adleman (RSA) algorithm is proposed.Firstly, two plain characteristic parameters (PCP) of the plain image are extracted and two random numbers are chosen.Then, a new parameter transformation model (PTM) is constructed to do nonlin
