These results can be intuitively explained by interactive cryptic effects between the shapes of the contrasting markings and attributes of the background.
Thus, attributes of the background, such as colour, patch size, or shape, and the number of colour components, may affect the background dependence of the camouflage effect mediated by colour-markings.
The first peak of the intensity distribution histogram cannot be attributed to the background only because of its longer tailing in comparison to the signal measured with the aqueous phase switched off, which amounted to only 2.8 ± 1.9 counts.
These lines are attributed to the background drapery of the hidden portrait as they are not related to any compositional element of the Ecce Homo.
In this figure, algorithm start to track the football player in the playground, when the player move to the shadow of playground, because of the loss of differentiated attributes of target with background, the algorithm cannot correctly track the object and usually the target position will obtain with errors.
We therefore attribute a small part of the background fluorescence in the XEOL-XANES to this material, and the increase in the Cu-edge height to its partial breakdown and removal, possibly in reactions with ozone generated by the beam.
Each scene was unique in that it varied in several randomly selected attributes, including: (a) the background colour of the screen; (b) the location of ellipses on the screen; (c) the colour, size and orientation of ellipse segments; (d) the typographic character, clearly distinct in size from the foreground objects; and (e) the colour of the typographic character.
One of the major challenges in the electrical or impedance based detection is low signal-to-noise ratio when compared to optical detection, which is attributed to the large magnitude of the background signal [3].
As can been seen in Figure 11, the increase in the variance of sub-profiles 2, 8, and 9 may be attributed to the imprecise DC estimation of the background.
Since in the object detection problem the answer is not a simple "yes" or "no" value (an object could be detected partially, or conversely part of the background could be attributed to the object), a fuzzy definition of True Positives, False Positives and False Negatives is needed.
Be mindful of the background.
