Embodiment Construction
[0064] The simulation image and the actual ultrasonic image test are carried out on the method for automatically selecting the optimal homogeneous region of the ultrasonic image proposed by the present invention. In order to more intuitively test the effectiveness of the method for selecting the homogeneous region of the ultrasonic image of the present invention, the speckle noise reduction effect based on the homogeneous region selection of the ultrasonic image is also used for comparison.
[0065] 1. The selection of homogeneous areas in ultrasound simulation images, and the speckle noise reduction experiment based on the selection of homogeneous areas.
[0066] Using approximate solutions for homogeneous regions, manual selection of homogeneous regions, and automatic selection of homogeneous regions by the method of the present invention, three different homogeneous region selection methods are used for homogeneous region selection and SRAD speckle reduction based on homoge...
