Abstract
An imaging apparatus includes: a moving body detecting section that detects if an object in an image is a moving body which makes a motion between frames; and an attribute determining section that determines a similarity indicating whether or not the object detected as the moving body is similar among a plurality of frames, and a change in luminance of the object based on a texture and luminance of the object, and, when determining that the object is a light/shadow-originated change in luminance, adds attribute information indicating the light/shadow-originated change in luminance to the object detected as the moving body.
Claims10
An imaging apparatus comprising:
- a moving body detecting section that detects if an object in an image is a moving body which makes a motion between frames;
- and
- an attribute determining section that (1) performs light/shadow detection on the object by determining (a) a similarity indicating whether or not the object, detected as the moving body by the moving body detecting section, is similar among a plurality of frames, and (b) a change in luminance of the object based on a texture and luminance of the object, and, (2) when determining that the object detected as moving is instead detected due to a light/shadow-originated change in luminance rather than due to moving, adds attribute information indicating the light/shadow-originated change in luminance to the object detected as the moving body.
A moving body detecting method comprising the steps of:
- detecting if an object in an image, output by an imaging section, is a moving body which makes a motion between frames;
- and
- performing light/shadow detection on the object by determining (a) a similarity indicating whether or not the object, detected as the moving body, is similar among a plurality of frames, and (b) a change in luminance of the object based on a texture and luminance of the object;
- and,
- when determining that the object detected as moving is instead detected due to a light/shadow-originated change in luminance rather than due to moving, adding attribute information indicating the light/shadow-originated change in luminance to the object detected as the moving body.
A moving body detecting circuit comprising:
- a moving body detecting section that detects if an object in an image is a moving body which makes a motion between frames;
- and
- an attribute determining section that, (1) performs light/shadow detection on the object by determining (a) a similarity indicating whether or not the object detected as the moving body, by the moving body detecting section, is similar among a plurality of frames, and (b) a change in luminance of the object based on a texture and luminance of the object, and, (2) when determining that the object detected as moving is instead detected due to a light/shadow-originated change in luminance rather than due to moving, adds attribute information indicating the light/shadow-originated change in luminance to the object detected as the moving body.
A program embodied on a non-transitory computer readable medium for allowing a computer to execute:
- a step of detecting if an object in an image is a moving body which makes a motion between frames;
- and
- a step of performing light/shadow detection on the object by determining (a) a similarity indicating whether or not the object, detected as the moving body, is similar among a plurality of frames, and (b) a change in luminance of the object based on a texture and luminance of the object;
- and
- when determining that the object detected as moving is instead detected due to a light/shadow originated-change in luminance rather than due to moving, adding attribute information indicating the light/shadow-originated change in luminance to the object detected as the moving body.
