![]() ![]() Thus, the embedding capacity got increased to be ( k + 1)/2 k bpp. Compared with the matrix encoding scheme, it used one more cover pixel to embed one more bit while the cost remain unchanged. ( 2007) proposed the “Hamming+1” scheme in 2007. Based on the matrix encoding, Zhang et al. ![]() The embedding capacity reached k/(2 k − 1) bit per pixel (bpp). In this scheme, k bits were embedded into 2 k − 1 cover pixels by modifying the least significant bits (LSBs) of one pixel. 2010).Ĭrandall originally proposed a data hiding scheme named matrix encoding (Crandall 1998) in 1998. One of the explorations to achieve this goal is applying the error correcting code to data hiding, and many researchers have done a lot of research in this area (Chang and Chou 2008 Chen et al. Such adaptive data hiding schemes are typically realized by first defining the cost of changing each pixel and then embedding the additional data while minimizing the sum of costs of all changed pixels. ![]() The current trend calls for constraining the embedding changes to image segments with complex content. Historically, the design of data hiding schemes for digital images has heavily relied on heuristic principles (Feng et al. These carriers are typically digital media files transmitted on the Internet, such as images, audios, videos, or text (Ker et al. Data hiding, frequently interchangeably referred to as information hiding, is the art of embedding additional data in a certain carrier (Zielińska et al. ![]()
