Sentence examples for modifiable coefficients from inspiring English sources
In PSB, discrepancy is used to determine the maximum number of modifiable coefficients within a block.
Therefore the actual maximum number of modifiable coefficients for block,, is calculated through the following expression: (6).
The modifiable coefficients are accurately selected in order to preserve the visual and the statistical characteristics of the cover image.
The embedded message is scattered across the image using a PRNG seeded by the stegokey that permutes the order of the modifiable coefficients.
represents the maximum number of modifiable coefficients for block according to discrepancy, but without considering the preliminary exclusions illustrated in Section 2.2.1.
These superior performances are achieved by taking into account discrepancy and quantization matrix in order to select the modifiable coefficients set.
A modifiable coefficient can hold as many bits as the entropy of the binary alphabet associated to its group : (14).
thus offsets can be only 1 or 2. PSB embeds the message by changing modifiable coefficient offsets, thus only unitary increments/decrements are possible, for example, a coefficient whose value is, after embedding could be only 2 or 3 (its group is ).
We have assumed that each interaction coefficient is independently modifiable whereas in natural populations traits may affect many interactions simultaneously.
According to the proposed inserting-removing strategy, the stream a of nonrounded DCT coefficients obtained from the blocks a q is divided into three sets: modifiable c m = a ∈ (-∞; -1.5) ∪ (1.5;∞), removable c R = a ∈ [-1.5; -0.5) ∪ (0.5 1.5], and insertable c Ins = a ∈ [-0.5; -0.25) ∪ (0.25 0.5]. Set c unifies modifiable, insertable, and removable sets (i.e., c = c m ∪ c R ∪ c Ins ).
