At first, a value is assigned to the similarity of block orientation field of two-fingerprint images.
This paper presents a method of determining the overall optimal block orientation using 3ds Max software with linear regression models.
The HOG feature vector of an image window (with 49 blocks) is a concatenated vector of all 49 normalized block orientation histogram ( H ^ b ), and will have a dimension of 1 × 1764 in our case.
Based on this principle, we determine the fixed angle by searching for the highest cross correlation and take the first of the highest cross-energy (correlated) blocks as the principle block (orientation) and then cycle-shift all the coefficients in reference to the principle orientation.
Approximately 13% of urban blocks are too long, some blocks are very large or very small, some areas have so many 4-way intersections, some areas have low permeability, majority of urban blocks have some cracks and the west side of neighborhood has an improper urban block orientation.
Under a WGD scenario, the expectation was that block orientation would be conserved if blocks were formed by reciprocal translocations among duplicate chromosomes.

In the second, third and fourth stimulation blocks, orientation still varied randomly from one stimulus presentation to the next, but the contrast was fixed to one value at a time for each block: either low, medium or high (Fig. 1A).
In the second, third and fourth stimulus presentation blocks, orientation still varied randomly (blockwise randomization), but the contrast within each block was fixed: in the second block to low contrast only, in the third block to medium contrast only, and in the fourth block to high contrast only (Fig. 1A, "low", "medium" and "high contrast").
In order to avoid this, the blocks' orientations in the centrifuge carriage were reversed after 2.5 min and the blocks were spun a second time for 2.5 min to obtain consistent amounts of purified products.
The research proposes a novel hierarchical multispectral palmprint recognition method based on block dominant orientation code (BDOC).
The fractal code of v is determined based on the location of the most similar domain block, the orientation k, the contrast p, and the brightness q.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
