Each pixel in images used for quantification corresponded to 1.00 µm2.
"More precisely," the artists explain on their website, "the images are considered in a pixel-by-pixel manner, and for each pixel of the an appropriate building block is placed at the corresponding place in the panel.
Therefore, pixels in the same scratch can have very different intensity values, if the scratch passes across darker and brighter areas.
For example Pixel in the Courtyard has a bed and a vintage caravan in a large warehouse space, while Pixel on the Water is a drag boat floating in Linz's harbour.
We propose to the user a set of possible scratches, and he has to select one of the candidates for the next steps in the scratch analysis process.
The main difference, in addition to the search direction, is the Gaussian function, which has its peak on the pixels of the scratch core, and a variance which depends on the last computed scratch thickness: (4).
If we increase the "local" weight, we increase the probability to include "good" pixels into the scratch to be restored (Figure 7 e)).,,, and are the same of (3). is the next upper (lower) pixel to be examined in the same column of. is a Gaussian function, evaluated in, with a peak in correspondence with the pixel in column of the scratch core, and a variance which is shown in (5).
The symmetry is calculated for all pixels in the image.
While conventional raster scanned image readouts implicitly embed pixel addresses in the output order, selectively sending pixels that change require an address tag for each pixel.
The new 16.8 million pixel device has seven active transistors for each pixel.
