Sentence examples for double compressed from inspiring English sources

Since [11, 12] needs special setup, we have trained various quality-specific SVM classifiers using single compressed and aligned double compressed images at different compression qualities.

However, DCT coefficients of single compressed and nonaligned double compressed image follow it.

As discussed in Section 2, most of the FDPD-based algorithms use SVM classifier, which needs prior training with FDPD of single compressed images and double compressed images.

Hence, FDPD-based tampering localization techniques train SVM classifier using FDPD of single compressed images and their aligned double compressed counterparts [11, 12].

DCT coefficients of single compressed images follow a generalized Benford's model; aligned double compressed images do not follow this model [15].

In [10], the authors showed that if double compressed image is recompressed by aligning the DCT grid with the primary compression grid, histogram of the resultant DCT coefficients shows higher magnitude.

FDPD of single compressed images serves as a feature of tampered region and FDPD of aligned double compress region serves as a feature of the untampered region.

(iii) Aligned double JPEG compressed (ADJPEG in short): When the ASJPEG patches undergo another JPEG compression and the block structures of the two JPEG compressions are aligned with each other, the output image patches are called ADJPEG patches.

(iv) Shifted double JPEG compressed (SDJPEG in short): When the ASJPEG patches undergo another JPEG compression and the block structures of the two JPEG compressions are different, the output image patches are called SDJPEG patches.

Given that the electric double layer is compressed with higher salt concentrations, the effective membrane thickness becomes thinner (Table 2).

The zeta potential also decreases more rapidly when the double layer is compressed at high ionic strength (Brooks and Seaman 1973; Vane and Zang 1997).
