Abstract

The invention relates to a real-time foreground extraction method based on a monocular platform and a device thereof. The method comprises the following steps of acquiring a monocular video frame sequence image; reducing the size of the image, and reducing a majority of calculation amount through reducing the size of the image; extracting a target prospect by means of a sequence frame statistics method; eliminating isolated noise by means of modes such as mean filtering and median filtering; connecting broken parts by means of a morphological method, and obtaining each target blob; extracting the contour of each blob and eliminating holes; eliminating false targets according to a blob characteristic; repairing a damaged edge by means of a specific filter; performing background updating by means of a block updating strategy; amplifying the vector edge of the target foreground, and obtaining an original resolution foreground vector edge; eliminating sawteeth which are caused by amplification; and filling the inner part of the vector edge by a foreground color, filling the rest part by a background color, and outputting the foreground image with the original resolution size. The invention further discloses a real-time foreground extraction device based on the monocular platform.

Description

technical field

[0001] The present invention relates to the field of image processing, in particular to a monocular platform-based real-time foreground extraction method and a monocular platform-based real-time foreground extraction device. Background technique

[0002] Both the background and the foreground are relative concepts. Take the highway as an example: sometimes we are interested in the cars coming and going on the highway. At this time, the car is the foreground, and the road surface and the surrounding environment are the background; sometimes we are only interested in the intrusion Pedestrians on the highway are interested, where the intruder is in the foreground and other things, including cars, are in the background.

[0003] At present, the development of image processing technology based on PC is becoming more and more mature, but due to the large size of the PC itself, poor portability, and poor long-term running stability, the scope of application is limit...
