Abstract
An apparatus includes a reproducing unit configured to reproduce and display video data captured by an imaging apparatus in a predetermined display area on a display device; a feature area detecting unit configured to detect a plurality of feature areas based on feature information that is registered in advance for a tracking target, in a first frame of the video data displayed by the reproducing unit; and a tracking area detecting unit configured to detect an area including the plurality of feature areas as a tracking area that includes the tracking target, based on a distance between the plurality of feature areas detected by the feature area detecting unit.
Claims16
An image processing apparatus, comprising:
- processing circuitry configured to
- reproduce and cause display video data captured by an imaging apparatus to be displayed in a predetermined display area on a display;
- register a reference color corresponding to a color included in a tracking target as feature information;
- detect a plurality of two-dimensional feature areas, based on the feature information that is registered in advance for detecting the tracking target, in a first frame of the displayed video data;
- and
- determine an area that encompasses the plurality of two-dimensional feature areas as a tracking area that includes the tracking target, based on a distance between pixels in the detected plurality of two-dimensional feature areas,
- wherein the processing circuitry is further configured to
- obtain a first image by extracting an area including a pixel with a color that is included in a predetermined color range that includes the reference color in at least a partial area of the first frame,
- obtain a second image by binarizing the first image,
- obtain a third image in which one or more blocks that are obtained in the second image through the binarizing are distinguished from one another, and
- when a pixel value of an area of the first frame corresponding to each of the blocks of the third image is included in the predetermined color range, detect the area as the feature area.
