They are used to evaluate the smoothness of a given image X along the horizontal, vertical, and diagonal directions by computing the so-called directional residuals W(k) = K(k) ⋆ X, where ' ⋆' is a mirror-padded convolution so that W(k) has again n1 × n2 elements.
Estimating directions by computing linear regression of neighbors of the three pixels in bold (c).
We will prove both directions by contradiction.
Amplicons were sequenced in both directions by Macrogen (Seoul, South Korea).
We have, now, rough directions and distances by computing from estimated source location and known each subarray location.
In DLEP, for a given image the local extrema in 0°, 45°, 90°, and 135° directions are obtained by computing local difference between the center pixel and its neighbors as shown below: I^{prime} (g_{i} ) = I(g_{c} ) - I(g_{i} );quad i = 1,2, ldots,8 (6)The local extremes are obtained by Eq. (7).
This tendency to keep the bending direction can be quantified by computing the autocorrelation function of the bending angle (Fig. 5).
The resultant speed relative to the ground (ground speed) and direction of travel relative to the preferred direction (drift angle) are determined by computing the vector sum of the wind and the bird's own velocity (see Methods and Figure 1).
In addition, the quadruplet test is often able to determine the direction of a conversion event by computing the probabilities of going down within the common maximum descent regions of the two triplets and determining the significance of the difference between the two probabilities based on a binomial distribution [ 12].
If Ψ ( v ) ≤ τ, then we start a new outer iteration by performing a μ-update, i.e., μ + : = ( 1 − θ ) μ ; otherwise, we enter an inner iteration by computing the search directions using (52) and (50) at the current iterates with respect to the current value of μ and apply (53) to get new iterates.
