Sentence examples for correlation among pixels from inspiring English sources

After that, they revealed the resizing by investigating the periodicity correlation among pixels.

Firstly, according to the spatial correlation among pixels, a pixel-adaptive anisotropic filter is designed to reconstruct the distorted signal.

The distance value D helps analyze the correlation among pixels and decides whether they can be classified as the same superpixels or not.

A study [5] introduces a few methods for lossless compression of encrypted grayscale and color images by employing LDPC codes to various bit planes and exploiting the spatial and cross-plane correlation among pixels.

The correlation models in Equations 11 and 12 capture the spatial correlations among pixels within each patch using R and p. The patch similarities, captured in the distance matrix, are used to 'modulate' these correlations with the Kronecker product to provide the full multi-patch correlation model.

These features enable examination of color differences between areas, partially solving the problem of correlations among pixels.

The basic reason is that a great number of the absolute differences of groups of two adjacent pixels range from 0 to 4 due to strong correlation among neighboring pixels.

Weng et al. presented in [13] a reversible data hiding scheme based on integer transform and on the correlation among four pixels in a quad.

This is because the correlation among neighboring pixels in e I increases in low PSNR (low bit rate) coding of the LDR image as indicated in Figure 18.

Markov random fields are often used in image processing applications, because this approach defines a model for describing the correlation among neighboring pixels [15].
