It not only covers schemes in traditional VC and extended VC for binary secret images, but also the latest development in the analysis-by-synthesis approach...This book distinguishes itself from the existing literature in three ways. First, it not only reviews traditional VC for binary secret images, but also covers recent efforts in improving visual quality for gray scale secret images. Second, not only traditional quality measures are reviewed, but also measures that were not used for measuring perceptual quality of decrypted secret images, such as Radially Averaged Power Spectrum Density (RAPSD) and residual variance, are employed for evaluating and guiding the design of VC algorithms. Third, unlike most VC books following a mathematical formal style, this book tries to make a balance between engineeringintuition and mathematical reasoning. All the targeted problems and corresponding solutions are fully motivated by practical applications and evaluated by experimental tests, while important security issues are prese | | 出版日期 | Book 2020 | | 關(guān)鍵詞 | Data Decryption; Cryptosystem; Privacy Protection; Radially Averaged Power Spectrum Density (RAPSD); Vis | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-13-8289-5 | | isbn_softcover | 978-981-13-8291-8 | | isbn_ebook | 978-981-13-8289-5Series ISSN 1860-4862 Series E-ISSN 1860-4870 | | issn_series | 1860-4862 | | copyright | Springer Nature Singapore Pte Ltd. 2020 |
