General Expansion-Shifting Model for Reversible Data Hiding: Theoretical Investigation and Practical Algorithm Design.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Sep2022, Vol. 32 Issue 9, p5989-6001. 13p.

Abstract: As a specific data hiding technique, reversible data hiding (RDH) has recently received extensive attention. By this technique, both the embedded data and the original cover image can be exactly extracted from the marked image. In our previous work, a ...

Grayscale-Invariant Reversible Data Hiding Based on Multiple Histograms Modification.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Sep2022, Vol. 32 Issue 9, p5888-5901. 14p.

Abstract: Grayscale-invariant reversible data hiding (GI-RDH) in color images is a data embedding framework in which the grayscales of a marked color image must be identical to those of the host color image. Recently, some state-of-the-art GI-RDH schemes were pr...

Reversible Data Hiding for Color Images Based on Adaptive Three-Dimensional Histogram Modification.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Sep2022, Vol. 32 Issue 9, p5725-5735. 11p.

Abstract: Reversible data hiding (RDH) is a hot research topic, and many related techniques are proposed, but only a few are devised for color images. Most current RDH schemes, including those for color images, follow a well-developed framework: histogram-based ...

Adaptive Reversible Data Hiding With Contrast Enhancement Based on Multi-Histogram Modification.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Aug2022, Vol. 32 Issue 8, p5041-5054. 14p.

Abstract: Reversible data hiding with contrast enhancement (RDH-CE) is proposed to aim at improving the contrast of images while embedding data. After deeply analyzing and studying the RDH-CE method proposed by Jafar et al., it is found that there are three main...

Reversible Data Hiding Based on Multiple Adaptive Two-Dimensional Prediction-Error Histograms Modification.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Jul2022, Vol. 32 Issue 7, p4174-4187. 14p.

Authors:

Abstract: Pairwise prediction-error expansion (pairwise PEE) is an efficient reversible data hiding technique based on two-dimensional (2D) histogram modification. However, without considering the image content, its embedding manner lacks adaptivity. In this pap...

Shadow detection of soil image based on density peak clustering and histogram fitting.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 3, p2963-2971. 9p.

Abstract: Shadow detection is a significant preprocessing work that soil type is classified with machine vision. Thus, Density peak clustering based on histogram fitting(DPCHF) is proposed to segment soil image shadows. First, its clustering centers are adaptive...

Extended framework for Sindhi numerals OCR using gradient orientation histograms.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 2, p2045-2056. 12p.

Abstract: The accuracy on MINST dataset for roman numerals is already 99.65%. However, same models showed low accuracy on Sindhi numerals. It is because Sindhi numerals have high correlation between the shapes of the numerals. In this paper, correlation based te...

Morphological geodesic active contour algorithm for the segmentation of the histogram‐equalized welding bead image edges.

Publication Type: Academic Journal

Source(s): IET Image Processing (Wiley-Blackwell). Aug2022, Vol. 16 Issue 10, p2680-2696. 17p.

Abstract: Assessment and evaluation are the essential processes of industrially manufactured products for the determination of the quality and quantity of products. They give justifications in a practical way about whether the machine is perfect or imperfect, wh...

Calculating the Climatology and Anomalies of Surface Cloud Radiative Effect Using Cloud Property Histograms and Cloud Radiative Kernels.

Publication Type: Academic Journal

Source(s): Advances in Atmospheric Sciences. Dec2022, Vol. 39 Issue 12, p2124-2136. 13p.

Abstract: 摘要: 云辐射内核已经被广泛应用于分析云属性的变化如何影响大气层顶的辐射通量, 而云辐射效应对地表温度的影响是通过地表辐射通量来直接实现的, 因此本研究使用快速辐射传输模式开发了一套同时适用于大气层顶辐射和地表辐射的云辐射内核. 云顶气压对大气层顶的辐射通量影响显著, 而云底气压对地表云辐射效应有着更重要的影响, 因此标准的大气层顶云辐射内核在各区域和月份中是云顶气压和云光学厚度的函数, 而地表云辐射内核则是云底气压和云光学厚度的函数. 考虑到卫星产品通常提供云顶高度而非云底高度, 本研究使用卫星观...

Trace Concealment Histogram-Shifting-Based Reversible Data Hiding with Improved Skipping Embedding and High-Precision Edge Predictor (ChinaMFS 2022).

Publication Type: Academic Journal

Source(s): Mathematics (2227-7390). Nov2022, Vol. 10 Issue 22, p4249. 21p.

Abstract: Reversible data hiding (RDH) is a special class of steganography, in which the cover image can be perfectly recovered upon the extraction of the secret data. However, most image-based RDH schemes focus on improving capacity–distortion performance. In t...
