A Survey of AM-FM methods for Applications in Medical Imaging

چکیده
Amplitude-Modulation FrequencyModulation (AM-FM) decompositions represent images using spatially-varying sinusoidal waves and their spatially-varying amplitudes. The model uses different scales and bandpass filters to characterize the wide range of frequencies that may be present in an image. In the past few years, as the understanding of its theory advanced, AM-FM has been used in a series of medical imaging problems ranging from ultrasound to retinal image analysis, yielding excellent results. This paper summarizes the theory of AM-FM and some of its main medical imaging applications: carotid artery ultrasound, pneumoconiosis, diabetic retinopathy, and age-related macular degeneration.

Amplitude-modulation frequency-modulation (AM-FM) decompositions represent images using spatially-varying sinusoidal waves and their spatially-varying amplitudes. AM-FM decompositions use different scales and bandpass filters to extract the wide range of instantaneous frequencies and instantaneous amplitude components that may be present in an image. In the past few years, as the understanding ...
متن کاملAM/FM halftoning: digital halftoning through simultaneous modulation of dot size and dot density
Conventional digital halftoning approaches function by modulating either the dot size (amplitude modulation or AM) or the dot density (frequency modulation or FM). Generally, AM halftoning methods have the advantages of low computation and good print stability, while FM halftoning methods typically have higher spatial resolution and resistance to Moiré artifacts. In this paper, we present a new...
متن کاملApplications of gold nanoparticles for medical imaging
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
متن کاملAM/FM halftoning: a method for digital halftoning through simultaneous modulation of dot size and dot placement
Conventionally, digital halftoning is accomplished by either changing the size of printed dots or changing the relative density of dots on the page. These two approaches are analogous to amplitude modulation (AM) or frequency modulation (FM) used in communications. A typical AM halftoning method, such as cluster dot screening, has very low computational requirements and good print stability. Ho...
