A new fragile watermark for image was proposed, which can be used in image verification applications. The paper first described the above two techniques, some of which will be used in the method. Then it described the embedding and authentication process and also analyzed the method to show how it can survive some attacks. The experimental results show that the proposed method doesn’t need the watermark or original image on authentication side. It provides more security against attack, and can localize where the tempering has occurred.展开更多

Two conceits （concetti） are considered in analyzing Tintoretto＇s female imagery： （1） a fanciful invention of musica extravaganza; and （2） a Venetian allegory of bellezza. The first part of the essay discusses the provenance of the painting and the second part presents an iconographical interpretation of the imagery. This essay also focuses on the iconography of the painting based on viewing the subject and does not postulate on its iconography based on disappeared paintings or on a speculative decorative cycle on the theme of Hercules. Relying on well-documented research on music in Venice, on Mannerist practices, and on art theories during Tintoretto＇s life, some intriguing observations are made about the painting.展开更多
