    Abstract: A method and an apparatus for compensating image segmentation lines (20) are provided. In the method, image segmentation is applied to a medical image (42) captured by using a segmentation model (44) to obtain a segmentation image (46) including at least one segmentation line (12a) between multiple layers in the medical image. Convolution computation is then performed on the segmentation image (46) by using a kernel (60, 60a) of a trained classification model (50) to predict a location of a next pixel connected to a current pixel in the respective segmentation line (12a) within the segmentation image (46), in which the pixel to be predicted is limited to a neighboring pixel of the current pixel in a prediction direction. The predicted pixels are connected to form a compensated segmentation line (14a) for each segmentation line (12a).

    Abstract: A method for segmenting a feature of interest from a volume image acquires image data elements from the image of a subject. At least one view of the acquired volume is displayed. One or more boundary points along a boundary of the feature of interest are identified according to one or more geometric primitives defined by a user with reference to the displayed view. A foreground seed curve defined according to the one or more identified boundary points and a background seed curve encompassing and spaced apart from the foreground seed curve are formed. Segmentation is applied to the volume image according to foreground values that are spatially bounded within the foreground seed curve and according to background values that lie outside the background seed curve. An image of the segmented feature of interest is displayed.

    Abstract: This application provides a tab bending detection method and apparatus, an electronic device, and a storage medium. The method includes: performing skeleton extraction on a sectional image of multiple layers of tabs to obtain a skeleton image of the multiple layers of tabs; merging damaged connected components in the skeleton image to obtain a merged connected component, where the damaged connected components are connected components on which breaking occurs in a same tab section; calculating a target number of the multiple layers of tabs based on the merged connected component and an undamaged connected component; and detecting, based on the target number and a preset number, whether any tab in the multiple layers of tabs is in a bending state. The damaged connected components are merged to obtain the merged connected component. The target number of the multiple layers of tabs calculated based on the merged connected component and the undamaged connected component is more accurate, thus making the tab bending detection more accurate.
