Filed: 2019-07-30
Abstract: To provide signal processing devices and methods for estimating transform between signals using a least squares technique.SOLUTION: A direct least squares method applies a seed transform candidate to a reference signal and measures correlation between the transformed reference signal and a suspect signal. For each candidate, update coordinates of reference signal features are identified in the suspect signal and provided as input to a least squares method to compute an update to the transform candidate. At an end of a process, the method identifies transform or set of top transform on the basis of further analysis of the correlation. A phase estimation method estimates a phase of reference signal components in the suspect signal using a point spread function. A phase deviation method determines parallel translation between the reference signal and the suspect signal by analyzing a phase deviation surface created by computing a deviation metric for phase shift estimation.SELECTED DRAWING: Figure 2
