Abstract

The invention is applicable to the technical field of image processing, and provides a brain white matter region segmentation method and device for a craniocerebral ultrasonic image and electronic equipment. The method comprises the following steps: carrying out diffusion and enhancement on an original input ultrasonic image, and then carrying out rough segmentation on the processed ultrasonic image to obtain a target image containing a brain white matter area and other non-interested areas; and carrying out secondary segmentation on a narrowed area, and removing the non-interested areas in the frame to obtain an accurately segmented brain white matter area. The invention can effectively avoid the problems that there is no clear boundary between an interested area and the surrounding environment in an ultrasonic image, the proportion of a brain white matter area is too low, and veins and other highlight areas have very strong negative effects on a segmentation result. Meanwhile, the white matter area segmentation device of the craniocerebral ultrasonic image and the electronic equipment provided by the invention can also achieve the same technical effect.

Description

Technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a brain white matter region segmentation method, device and electronic equipment of craniocerebral ultrasound images. Background technique [0002] Traditional white matter ultrasound image analysis methods use manual segmentation. If the damaged parts of the brain white matter are the anterior horn of the lateral ventricle, the white matter near the posterior horn, the lateral and dorsal white matter of the lateral ventricle, or the subcortical white matter, the accuracy of manual segmentation is likely to be affected by the operator's experience level and cause artificial errors. In addition, traditional methods perform feature extraction and classification after manual segmentation, which consumes a lot of manpower and material resources. [0003] The difficulty in segmentation of the white matter region of ultrasound images is that the image contrast is low, es...
