1. A smoke detection system, comprising:
a camera configured to acquire a current image and a previous image;
a storage unit configured to store a plurality of modules; and
a processor coupled with the camera and configured to execute the plurality of modules to:
generate a difference image based on the current image and the previous image;
input the current image and the difference image to a semantic segmentation model so that the semantic segmentation model outputs a smoke confidence map, wherein the smoke confidence map is generated based on whether a current environment is a dark environment or a bright environment; and
analyze the smoke confidence map to determine whether a smoke event occurs in the current image.
