Abstract: In various examples, cached sensor data captured by an ego-object and ego-motion of the ego-object are used to reconstruct the area under the vehicle in real time. For example, image data captured over time by a vehicle may be cached into a composite map that visualizes the ground or drivable area, and the vehicle's ego-motion may be used to retrieve a region of the composite map corresponding to the under vehicle area. For each time slice, a newly captured or generated image representing that time slice may be used to generate a local map of an observed portion of the ground, and the local map may be merged with a composite map that represents previously observed local maps. Accordingly, the under vehicle area for that time slice may be reconstructed by retrieving corresponding pixels from the composite map using the vehicle's ego-motion.

Abstract: A degradable cardiac pacing current-providing wire, comprising: conductive core; insulating film ,covering said conductive core, wherein said conductive core is made of magnesium alloy, the weight percentage of said magnesium alloy is: zinc 4.5-5.5%, manganese 0.8-1.2%, calcium 0.8-1.2%, and the remainder is magnesium, said insulating film is made of either or at least two copolymers of Polylactic acid (PLA), Polyglycolic acid (PGA), Polycaprolactone (PCL), Polydioxanone (PDS) and Polyhydroxyalkanoate (PHA). A cardiac pacing current-providing unit, for use in providing pacing current to the heart of the patient, comprising: wire; suture needle and connecting electrode which is connected to the cardiac pacemaker, there is no wire residue in the body after degradation, and no metal artifacts will occur, which makes the patients free from the need for re-operation, and reduces the mental, physical and economic burden caused by the operation, has a strong clinical application value.

Abstract: The present disclosure discloses a method and apparatus for determining a to-be-superimposed area of an image, superimposing an image and presenting a picture. The method for determining a to-be-superimposed area of an image in a scene picture comprises: acquiring a scene picture; determining a to-be-superimposed area in the scene picture; receiving a to-be-superimposed image based on a update request from a user, the update request including identity information of the to-be-superimposed image; and determining the to-be-superimposed area matching the to-be-superimposed image based on the identity information. The present embodiment realizes a partial update to the scene picture.
