The self-mixing interferometer is used to investigate the characteristics of resonant frequency of the microresonator, which is excited by a sinusoidally driven loud-speaker. The detected self-mixing signal is processed by the phase reconstruction method.
A generalized multiresolution likelihood ratio (GMLR), which can increase the distinction between different signals by fusing their more features, is defined. Multiresolution representation of image characterizes inherent structure of image well, and the
