A Dual Technique for Watermarking Color Digital Images
Principalele cerinţe impuse unui algoritm de watermarking viabil sunt: păstrarea calităţii imaginii gazdă şi rezistenţa marcajului introdus la cât mai multe tipuri de atacuri. În această lucrare autorii propun o metodă duală care combină o tehnică spaţială de marcare şi o tehnică bazată pe o transformare în frecvenţă. Cele două metode au proprietăţi complementare în ceea ce priveşte rezistenţa ...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولA Dual Digital-Image Watermarking Technique
Image watermarking has become an important tool for intellectual property protection and authentication. In this paper a watermarking technique is suggested that incorporates two watermarks in a host image for improved protection and robustness. A watermark, in form of a PN sequence (will be called the secondary watermark), is embedded in the wavelet domain of a primary watermark before being e...
متن کاملNeural Filtering Technique for Enhancing Digital Images
A new image enhancement technique proposed in this paper. The proposed neural filter is carried out in two stages. In first stage the corrupted image is filtered by applying a special class of multistate switching median filter. The filtered image output multistate switching median filter is suitably combined with a feed forward neural network in the second stage. The internal parameters of the...
