Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] A method for image similarity comparison according to an embodiment of the present invention is suitable for ultrasonic images whose edges form closed curves after the images are segmented. Since the 3D modeling of medical ultrasound images is generally independent organs, tumors or blood vessels and other tissues (the edges of sliced ​​images are all closed after segmentation), the present invention is applicable to 3D modeling of most ultrasound images. For different images with closed edges after segmentation, the positions of the centroids are generally different, and the Euclidean distance of the centroids of the images can be used to judge whether two images are similar or the same to a certain extent. At the same time, the image area is used as an au...

Abstract

The embodiment of the invention discloses an image similarity comparison method. Through two elements of the fusion division image mass center Euclidean distance and the division image area, the automatic comparison on pictures of ultrasound image sequence groups can be realized; the pictures with poorer quality can be selected and removed. The embodiment of the invention also discloses an image similarity comparison device and a computer readable storage medium. By using the invention, the direct embedment into the ultrasound image division algorithm can be realized; the division image robustness is improved; in addition, the labor resources can be greatly saved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for image similarity comparison. Background technique [0002] Compared with other medical diagnosis, color ultrasound Doppler diagnosis has the advantages of simplicity, safety, effectiveness and strong repeatability. The color ultrasound Doppler diagnosis equipped with a three-dimensional (3-Dimensional, 3D) probe can realize 3D imaging by using three-dimensional reconstruction. Since what the 3D probe acquires is a sequence of image slices (the sequence usually takes every 5mm as a frame, and each frame is an image to be processed), through the 3D reconstruction algorithm, these slices can be reconstructed into a 3D model . [0003] Compared with MRI (Magnetic Resonance Imaging, MRI) and Computed Tomography (CT), which have clear images, high resolution, and direct 3D imaging, ultrasound images have low resolution and poor imaging quality, so in 3D reconstruction Pr...
