4, which point out the guaranteed image quality, the more embedding capacity, and the less side information needed for the proposed algorithm.
However, the application of a perceptual uniform colour space alone does not guarantee improved image quality.
In order to guarantee both image quality and robustness, this study embeds the watermark into the middle-frequency parts LH3 and HL3 in DWT level-three.
When noise variance is larger than signal variance in one band or when the noise is not uniformly distributed between each band, PCA cannot guarantee that image quality decreases for principal components with lower ranking [6].
A major benefit of higher magnetic field strengths is that more signal is provided which can be used to shorten acquisition times, but higher magnetic field strengths do not always guarantee higher image quality per se.
Can there ever be any guarantee that images of children would indeed be safe, and instantly destroyed?
It might sound weird to use a full-size camcorder as a webcam, but you're guaranteed decent image quality, stereo sound, and it'll save you a few bucks.
6. Sports teams, athletes, and celebrities: Globatalent wants to create a decentralized marketplace where investors and fans can invest in clubs and players and trade benefits guaranteed by image rights, player transfers, price money, salaries, ticketing, TV contracts, or any other income.
First, for the histogram-based schemes, it has the advantage of guaranteed output image quality because the mean square error (MSE) between the marked and original image is limited to be below 1, leading to the result of at least 48.13 dB in PSNR value [3].
And though the names of many Seyffert subjects — Mellon, Taft, Lindbergh, Frick — are part of American history, that has not always guaranteed the images a place in homes or galleries.
We have also proposed a set of conditions to guarantee a successful image segmentation.
