A pde-Based Analysis of the Spectrogram Image for Instantaneous Frequency Estimation
Instantaneous frequency (IF) is a fundamental feature in multicomponent signals analysis and its estimation is required in many practical applications. This goal can be successfully reached for well separated components, while it still is an open problem in case of interfering modes. Most of the met...
