A Survey Of Sign Based Image Copy Detection Methods
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 3
Abstract
Abstract: The world wide web is filled with billions of images and redundant copies of images can frequently be found on many websites. These duplicates can be exact copies or differ slightly in their visual content. To assure privacy it is mandatory to preserve copyright verification, image-content identification, copy detection and authentication. This paper provides a comparative study on how content-based image copy detection methods are used to detect the copy of original image. The methods based on content based copy detection which includes signs of discrete cosine transform (DCT) and discrete wavelet transform (DWT), color histograms, by using concept of dual signature are presented.
