Abstract
An image processing system includes: a receiving unit configured to receive an input of a plurality of image frames constituting a video from an imaging apparatus; a detection unit configured to detect a feature point included in an image frame to be processed in the plurality of image frames; and an output unit configured to output an output image obtained by superimposing an image frame to be processed of an area detected as a feature point on a background image generated from at least some of a plurality of image frames.
Claims8
An imaging processing system comprising:
- a memory storing computer program instructions;
- and
- at least one processor configured to execute the computer program instructions to:
- generate a foreground image by extracting, from a first image frame, a difference area in which a difference from a background image is not less than a certain threshold;
- extract an edge portion from the generated foreground image;
- and
- generate a second image frame to be output by superimposing the edge portion and the background image,
- wherein transparency of the second image frame is dependent on an intensity of the edge portion.
An image processing method comprising:
- generating a foreground image by removing a background image from a first image frame;
- extracting an edge portion from the generated foreground image;
- and
- generating a second image frame to be output by duplicating the edge portion and the background image,
- wherein transparency of the second image frame is dependent on an intensity of the edge portion.
A non-transitory storage medium for storing a program causing a computer to execute an image processing method comprising:
- generating a foreground image by extracting, from a first image frame, a difference area in which a difference from a background image is not less than a certain threshold;
- extracting an edge portion from the generated foreground image;
- and
- generating a second image frame to be output by superimposing the edge portion and the background image,
- wherein transparency of the second image frame is dependent on an intensity of the edge portion.
