Class MPSNNLocalCorrelation

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSNNLocalCorrelation
extends MPSNNReduceBinary
    MPSNNLocalCorrelation The MPSNNLocalCorrelation filter computes the correlation between two images locally with a varying offset on x-y plane between the two source images (controlled by the window and stride properties) and the end result is summed over the feature channels. The results are stored in the different feature channels of the destination image, ordered such that the offset in the x direction is the faster running index. Given two images A and B, the output image has (2*windowInX + 1)*(2*windowInY + 1) feature channels, with each feature channel computed as: O(x, y, f(m, n)) = sum_z{A(x, y, z) * B(x + M[m], y + N[n], z)} where m runs from {0, 1, ... , (2*windowInX)}, n runs from {0, 1, ... , (2*windowInY)}, f(m, n) = n * (2*windowInY + 1) + m, M = {-windowInX*strideInX, (-windowInX + 1)*strideInX, ... 0 ... , (windowInX - 1)*strideInX, windowInX*strideInX}, N = {-windowInY*strideInY, (-windowInY + 1)*strideInY, ... 0 ... , (windowInY - 1)*strideInY, windowInX*strideInY}
