Despeckle Filtering for Multiscale Amplitude-Modulation Frequency-Modulation (AM-FM) Texture Analysis of Ultrasound Images of the Intima-Media Complex
Table 3
Statistical analysis between the low, medium and high AM-FM features extracted from the IMC for the automated segmentation measurements for the three different age groups, below 50 (<50), between 50 and 60 (50–60), and above 60 (>60) years old based on the Mann-Whitney rank sum test for all despeckle filtering techniques. Only the features that exhibited statistical significant differences at P < 0.05 are shown.
