Abstract

With regard to objects such as pictures, geometric figures, and symbols shown in the image to be processed by an image processing apparatus, in order to select an object that does not overlap in position with a user-indicated position, an image processing apparatus 100 acquires a user-indicated position in an image 200 in which an object 201 is shown, generates partition regions 209 that partition the target region of the image 200, on the basis of the position of the object 201, identifies a partition region 211 on the basis of a user-indicated position, and determines whether the object 201 has been selected, on the basis of the identified partition region 211.

Claims

1. An image processing apparatus comprising:

an indicated-position information acquiring unit that acquires indicated-position information, the indicated-position information including at least one user-indicated position in an image in which at least one object is shown;

a reference position information acquiring unit that acquires reference position information including a position of the object in the image and vertex coordinates of a target region of the image;

a partitioning unit that partitions the target region of the image on a basis of the reference position information to generate a plurality of partition regions;

a partition region identifying unit that identifies at least one partition region on a basis of the plurality of partition regions and the indicated-position information; and

an object determining unit that determines whether the object has been selected, on a basis of the identified partition region.

2. The image processing apparatus according to claim 1, wherein the object determining unit determines whether the object has been selected, on a basis of a position of the object or a region of the object.

3. The image processing apparatus according to claim 1, wherein,

the reference position information includes at least one position indicative of a boundary of the target region of the image, and

the object determining unit includes a region determining unit determines whether the partition region identified by the partition region identifying unit is related to the object, the object determining unit determining the object to have not been selected when the identified partition region is a partition region that is partitioned on a basis of a position indicative of a boundary of the target region of the image, and is determined to be not related to the object.

4. The image processing apparatus according to claim 1, wherein the partitioning unit acquires positions of sites in the image on a basis of the reference position information, and partitions the target region of the image on a basis of Voronoi boundaries defined on a basis of the positions of the sites to generate the plurality of partition regions.

5. The image processing apparatus according to claim 4, wherein the partitioning unit partitions the target region of the image on a basis of Delaunay boundaries defined on a basis of the positions of the sites and the Voronoi boundaries to generate the plurality of partition regions.

6. The image processing apparatus according to claim 1, wherein,

the indicated-position information includes information indicative of a user-indicated line segment or a user-indicated region, and

the partition region identifying unit identifies at least one partition region on a basis of the information indicative of the user-indicated line segment or the user-indicated region.

7. The image processing apparatus according to claim 1, wherein,

the image is an image in which the at least one object and at least one marker are shown,

the image processing apparatus comprises

a significant pixel region acquiring unit that acquires a significant pixel region shown in the image, and

a discriminating unit that discriminates the significant pixel region as one of the object and the marker, and

the indicated-position information acquiring unit includes a marker information acquiring unit that acquires the indicated-position information on a basis of the marker in the image.

8. The image processing apparatus according to claim 1, further comprising:

an associating unit that associates the indicated-position information with indicated-processing information indicative of user-indicated processing with respect to the object;

a first indicated-processing information acquiring unit that acquires the indicated-processing information that is associated with the indicated-position information used in the identifying of the identified partition region, and is related to the identified partition region;

a second indicated-processing information acquiring unit that acquires the indicated-processing information that is associated with the identified partition region used in the determining of the object determined to have been selected, and is related to the object; and

an object processing unit that executes, for the object determined to have been selected, processing indicated by the indicated-processing information related to the object.

9. An image processing method comprising:

acquiring indicated-position information, the indicated-position information including at least one user-indicated position in an image in which at least one object is shown;

acquiring reference position information including a position of the object in the image and vertex coordinates of a target region of the image;

partitioning the target region of the image on a basis of the reference position information to generate a plurality of partition regions;

identifying at least one partition region on a basis of the plurality of partition regions and the indicated-position information; and

determining whether the object has been selected, on a basis of the identified partition region.

10. A non-transitory computer readable medium storing a program causing a computer to function as:

an indicated-position information acquiring unit that acquires indicated-position information, the indicated-position information including at least one user-indicated position in an image in which at least one object is shown;

a reference position information acquiring unit that acquires reference position information including a position of the object in the image and vertex coordinates of a target region of the image;

a partitioning unit that partitions the target region of the image on a basis of the reference position information to generate a plurality of partition regions;

a partition region identifying unit that identifies at least one partition region on a basis of the plurality of partition regions and the indicated-position information; and

an object determining unit that determines whether the object has been selected, on a basis of the identified partition region.
