Abstract

The invention discloses a small sample image segmentation method based on a guide network and a full-connection conditional random field, and the method comprises the steps: carrying out the group division of an obtained to-be-segmented image, and obtaining a support image and a query image; marking positive sample points and negative sample points in the support image to obtain a foreground information feature map and a background information feature map containing positive and negative sample positions; based on the support image, the foreground information feature map and the background information feature map, extracting task features by adopting a guide network; performing preliminary segmentation according to the task features and the query image to obtain a preliminary segmentation result; carrying out edge refinement on the preliminary segmentation result based on a full-connection conditional random field to obtain a final segmentation result; inferring potential features of the support image by optimizing the guide network; performing preliminary segmentation on the query image without pixel annotation according to the potential features; and according to the preliminary segmentation result, carrying out finer segmentation through a full-connection conditional random field so as to obtain a relatively high segmentation result.
