Abstract: A method for improving wireless network connection is provided. The method is used in a mobile node moving in an area and includes: respectively receiving spatial information broadcasted by a root node and fixed nodes in a plurality of cells constituting the area, wherein each of the fixed nodes is directly connected to the root node, or indirectly connected to the root node through one or more other fixed nodes; obtaining current leakage weight values of the mobile node that is directly connected to the root node and is indirectly connected to the root node through the fixed nodes according to the spatial information received in each of the cells; generating a connection leakage table according to the largest one among the current leakage weight values; and determining a target position of the area which the mobile node moves to according to the connection leakage table.

Abstract: A method of removing raindrops from video images is provided. The method includes the steps of: training a raindrop image recognition model using a plurality raindrop training images labeled in a plurality of rainy-scene images; recognizing a plurality of raindrop images from a plurality of scene images in a video sequence using the raindrop image recognition model; and in response to a specific raindrop image in a current scene image satisfying a predetermined condition, replacing the specific raindrop image in the current scene image with an image region corresponding to the specific raindrop image in a specific scene image prior to the current scene image to generate an output scene image.
