Data acquisition was performed on a static configuration by recording direct and indirect solar loading during several days and was processed using advanced signal processing techniques in order to increase signal-to-noise ratio and signature contrast of the elements of interest.
By extending this analysis through the rising phase of solar cycle 23, we conclude that the functional dependence of the contrast of small elements results to be time independent, implying that the physical properties of the underlying flux tubes may not vary with time.
Boundaries are detected based on local contrast of visual elements, and are assigned to the figural region and not to the surrounding background region.
The contrast of all elements counterphase flickered at 2 Hz.
In Experiments 1 and 7, the contrast of the elements with the background was much lower.
Based on these results, we increased font sizes, changed the placement and color contrast of navigation elements and content, and simplified navigation options and operation of the video segments.
When the contrast of the elements with the background is lower (Exps. 1 and 7), however, abnormal fusion will be stronger, and targets and distractors will be easier to discriminate.
The network uses two codes: The difference in response between A- and N-neurons labels contour elements for incremental grouping, while the response of N-neurons codes the contrast of the contour elements.
In Experiments 5 and 6, the contrast of the search elements with the background was high, leading to inefficient search for interocular conflict as well as the absence of a search asymmetry.
For example, if you have chosen to use the Sharpen Filter, you will choose what percentage you want Illustrator to sharpen the contrast of the different elements of the graphic, image or text.
