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.
Claims20
An image processing system comprising:
- a memory;
- and
- at least one processor coupled to the memory,
- wherein the at least one processor is configured to perform operations comprising:
- receiving an input of an image frame;
- detecting a feature point from a part of or a whole the image frame, the feature point being an edge;
- and
- outputting, to a displayed screen, an output image with a first pixel value at a first position of a background image as a second pixel value, the first position of a background image corresponding to a position of the feature point detected in the image frame, the second pixel value being a value at which the first pixel value is changed to one of at least two different types values,
- wherein the background image is different from the image frame in which the feature point is detected.
An image processing method comprising:
- receiving an input of an image frame;
- detecting a feature point from a part of or a whole the image frame, the feature point being an edge;
- and
- outputting, to a displayed screen, an output image with a first pixel value at a first position of a background image as a second pixel value, the first position of a background image corresponding to a position of the feature point detected in the image frame, the second pixel value being a value at which the first pixel value is changed to one of at least two different types values,
- wherein the background image is different from the image frame in which the feature point is detected.
A non-transitory computer-readable storage medium storing a program that, if executed, causes a computer to perform operations comprising:
- receiving an input of an image frame;
- detecting a feature point from a part of or a whole the image frame, the feature point being an edge;
- and
- outputting, to a displayed screen, an output image with a first pixel value at a first position of a background image as a second pixel value, the first position of a background image corresponding to a position of the feature point detected in the image frame, the second pixel value being a value at which the first pixel value is changed to one of at least two different types values,
- wherein the background image is different from the image frame in which the feature point is detected.
