Image segmentation method and device, computer equipment and storage medium

Abstract

The invention relates to an image segmentation method and device, computer equipment and a storage medium. The method comprises the steps of sequentially selecting current image frames in a video according to a time sequence; determining a reference image frame from an image frame in which a timing sequence in the video is located in front of a current image frame; obtaining first position information of a target object key point in the reference image frame; affine transformation is carried out on the current image frame by referring to an affine transformation relation between the first position information and a target object key point template to obtain a target object graph of the current image frame; performing key point detection on the target object graph to obtain second positioninformation of a key point of the target object; segmenting a target object from the target object graph to obtain segmentation information of the target object; and segmenting the target object fromthe current image frame according to the segmentation information and the second position information. According to the scheme, the calculated amount is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image segmentation method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of science and technology, the application of various video technologies is becoming more and more extensive. There may be multiple objects in each frame of the video, and in some application scenarios, it is usually necessary to segment one of the target objects from the video image. For example, in the medical field, it is usually necessary to segment an image of a certain part from an ultrasound video image targeting a human body region. [0003] The traditional method is to segment the original image and optical flow in the video when segmenting a certain target object in the video image. Figure 1 And input to the convolutional neural network for encoding, and then the feature maps obtained after encoding are connected in series, an...
