In this paper, we describe new and improved attacks on the authentication scheme previously proposed by Yeung and Mintzer [1]. Previous attacks assumed that the binary watermark logo inserted in an image for the purposes of authentication was known. Here we remove that assumption and show how the scheme is still vulnerable, even if the binary logo is not known but the attacker has access to mul...

Existing logo detection methods usually consider a small number of logo classes and limited images per class with a strong assumption of requiring tedious object bounding box annotations, therefore not scalable to real-world dynamic applications. In this work, we tackle these challenges by exploring the webly data learning principle without the need for exhaustive manual labelling. Specifically...

A novel fragile watermarking technique is proposed for hiding logo information into an image by tuning block pixels based on a bitmap parity checking approach. A secure key and a random number generator are used to hide the logo information in a secret, undetectable, and unambiguous way. The characteristics of the mean gray value and the bitmap in a block are exploited for performing the embedd...

Sport video is an important video genre. Content-based sports video analysis attracts great interest from both industry and academic fields. A sports video is characterised by repetitive temporal structures, relatively plain contents, and strong spatio-temporal variations, such as quick camera switches and swift local motions. It is necessary to develop specific techniques for content-based spo...

anxiety disorders are a group of psychiatric disorders which can have negative effects on the human life. children and adults can have anxiety disorders and these disorders can lead to secondary problems such as cognitive, perceptual, emotional and behavioral problems. for treatment of anxiety, the practitioners and psychologists can apply psychotherapy approaches such as: cognitive therapy, ge...
