Classification: CPC G | IPC G

Claim 0:
1. An object detection method, for detecting a target object, comprising:
capturing at least two detection portions with a first aspect ratio from an input image with a second aspect ratio;
confirming whether any object is detected in each of the detection portions and obtaining corresponding boundary boxes for detected objects; and
removing or merging the boundary boxes, comprising:
defining at least one filtering region in the input image;
classifying the boundary box having an edge in the filter region as a candidate boundary box, and classifying the boundary box having no edge in the filter region as a maintained boundary box; and
removing the candidate boundary box from the boundary boxes if, AI
  MA
 

 is larger than a threshold value, wherein AI is the area of an intersection region of the candidate boundary box or the maintained boundary box, and MA is a minimum one of the areas of the candidate boundary box and the maintained boundary box;

wherein the first aspect ratio is different to the second aspect ratio.
