Lesion feature calculating device and method utilizing border sharpness

摘要

Provided is a device and method for calculating a lesion feature. The device includes a border discriminator configured to discriminate a border of a lesion on an image of an image signal, a border sharpness normalizer configured to normalize a border sharpness based on the border determined by the border discriminator and output the normalized border sharpness as a feature, and a vector generator configured to generate a vector having the feature outputted from the border discriminator as a component. Therefore, by using the lesion feature calculating device and method according to embodiments of the present invention, types of lesions on ultrasonic images are classified based on the borders of the lesions.

1. A lesion feature calculating device comprising:
a border discriminator configured to discriminate a border of a lesion on an image of an image signal; a border sharpness normalizer configured to normalize a border sharpness based on the border determined by the border discriminator and output the normalized border sharpness as a feature value; and a vector generator configured to generate a vector having the feature value as a component, wherein the border sharpness normalizer comprises:
a vertical pixel converter configured to collect pixels vertical to the border;a discrete fourier transform (DFT) converter configured to perform a discrete fourier transform on the pixels collected by the vertical pixel converter and output an average value; andan integrator configured to integrate the average value outputted from the DFT converter for a frequency band to output the feature value.
