ssd: Sum of squared differences (SSD)

In ragram: Radargrammetry

Description

Calculates the sum of squared differences (SSD) between two SAR-class objects. This method also works for RasterLayer-class objects. The minimum SSD value determines disparity.

Usage

ssd(master, slave, u1, v1, u2, v2, n = 3)

Arguments

master	SAR-class object (or a subclass e.g. Sentinel-class or TSX-class).
slave	SAR-class object (or a subclass e.g. Sentinel-class or TSX-class).
u1	Integer. Column, i.e. y coordinate of master pixel.
v1	Integer. Row, i.e. x coordinate of master pixel.
u2	Integer. Column, i.e. y coordinate of slave pixel.
v2	Integer. Row, i.e. x coordinate of slave pixel.
n	Integer. (Window size-1)/2 in x and y direction.
