However, it was developed for page regions and hence has some difficulties in handling the images like Fig. 1.
On the 'Block layout' page, click on the 'Demonstrate block regions' link to see all the regions that your theme provides, and where they are on the page; regions are specific to the theme that is currently active, which is Bartik by default.
First, we proposed an ROI setting method to deal with the non-page region problem.
After the dilation, the non-page region forms large CCs around the image boundaries.
In order to address these problems, we develop a non-page region detection algorithm and apply the binarization method in [21] to the ROIs as illustrated in the first stage of Fig. 3.
where |·| is the number of elements in the set, ∂ I is a set of pixels whose distance from the image border is smaller than δ, and α 1,α 2 are parameters that control the performance of the non-page region detection algorithm.
Allele Glu-B3f could not be reliably discriminated from Glu-B3g since these bands had very similar mobilities, including the presence of a band in the SDS-PAGE region as previously reported [ 7, 34, 41].
At the Glu-B3 locus, three alleles, Glu-B3d, Glu-B3h and Glu-B3i, each carried the slowest LMW-GS bands in the SDS-PAGE region B among the cultivars studied.
d Detected non-page regions from b. e Binarization result without non-page detection.
We remove detected non-page regions and then perform binarization on the remaining regions.
In order to prevent the disturbance of structure noise (e.g., page boundaries, blank regions, and scan errors), we find the the region of interests (ROI) by detecting and excluding the non-page regions.
