Embodiment approach

[0149] After determining the ultrasonic image to be processed, for each ultrasonic image to be processed, it is divided into a non-edge area and an edge area, which can be determined through three possible implementation methods:

[0150] Way 1: First, determine the gradient value of each pixel in the ultrasonic image to be processed, and obtain a preset proportion of the edge region corresponding to the ultrasonic image to be processed. During implementation, determine the gradient value of each pixel point, optionally, determine the gradient value of each pixel point by a sobel operator (Sobel operator, Sobel operator), assuming G; wherein, G is a non-negative value; in addition, The implementation of determining the gradient map in the present application is not limited to the sobel operator, for example, an optimization method of the sobel operator may also be used.

[0151] In addition, the preset proportion of the acquired edge area is assumed to be γ, where γ is a propo...

Abstract

The invention discloses an ultrasonic image processing method and a communication terminal. The method comprises: dividing a to-be-processed ultrasonic image into a non-edge region and an edge region;for each pixel point in the to-be-processed ultrasonic image, determining a dispersion degree value of a pixel value in each preset direction in a preset neighborhood of the pixel point; if the pixelpoints are the pixel points in the non-edge area, carrying out image filtering processing on the pixel points according to discrete degree values of the pixel points in all preset directions; and ifthe pixel points are the pixel points in the edge area, determining an edge direction according to the discrete degree values and the gradient values of the pixel points in each preset direction, andperforming directional smoothing processing and edge enhancement processing according to the determined edge direction. Through the method, the distinguishability and continuity of tissues and organsare improved, and the method is used for at least solving the problems of abrupt points, flicker points or image pasting caused by marginal enhancement in related technologies.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an ultrasonic image processing method and a communication terminal. Background technique [0002] The ultrasound imaging system acquires ultrasound images of tissues and organs according to the received ultrasound return signals of tissues and organs. Due to the inhomogeneity of the tissues and organs and the interference phenomenon of the ultrasound signal itself, the acquired ultrasound images have obvious speckle noise, and at the same time, the edges of the tissues and organs are not obvious enough. These problems not only affect the distinguishability and continuity of tissues and organs, but also reduce the accuracy and understandability of ultrasound images. [0003] In the related art, traditional isotropic filtering performs directional enhancement on edge area pixel points based on gradient values. This processing method will ...
