Abstract

A processing unit (workstation) is connected through a communication line to an image managing unit (server) to manage a data base in which real image data has been stored. A teaching data forming section of the processing unit forms mask teaching data indicative of an object outline with respect to thin-out image data obtained from the real image data stored in the data base as a target and transfers to the image managing unit as a server. A mask data forming section of the image managing section forms mask data indicative of the object outline from the real image data in the data base by using the transferred mask teaching data as a reference (guidance).

Claims

1. A distributed image processing apparatus, comprising:

an image managing unit to manage a data base in which real image data has been stored;

a processing unit connected to said image managing unit through a communication line;

a teaching data forming section within said processing unit for forming mask teaching data indicative of an outline of an object and transferring to said image managing unit with respect to thin-out image data obtained from the real image data stored in said data based as a target; and

a mask data forming section within said image managing unit for forming mask data indicative of the object outline from the real image data in said data base by using said mask teaching data transferred from said teaching data forming section as a reference.

2. An apparatus according to claim 1, wherein the thin-out image data derived from the real image data is previously stored in said data base.

3. An apparatus according to claim 1, wherein said teaching data forming section forms the mask teaching data indicative of the object outline with respect to said thin-out image data as a target in accordance with an instruction of an operator.

4. An apparatus according to claim 1, wherein said teaching data forming section automatically forms the mask teaching data indicative of the object outline with respect to said thin-out image data as a target.

5. An apparatus according to claim 1, wherein said teaching data forming section automatically forms the mask teaching data indicative of the object outline with respect to said thin-out image data as a target on the basis of outline information instructed by an operator.

6. An apparatus according to claim 5, wherein said teaching data forming section detects a boundary point on the basis of a designated point indicative of a position near the outline of the target object instructed by the operator, sequentially searching a boundary point on the outline from the boundary point detected, and forms the mask teaching data indicative of the object outline.

7. An apparatus according to claim 5, wherein said teaching data forming section searches the inside of the boundary region including the outline of the target object instructed by the operator and forms the mask teaching data indicative of the object outline.

8. An apparatus according to claim 5, wherein said teaching data forming section detects each boundary point on the basis of a plurality of designated point information indicative of positions near the outline of the target object instructed by the operator, sequentially searches a boundary point on the outline in accordance with a path connecting said plurality of boundary points detected, and forms the mask teaching data indicative of the object outline.

9. An apparatus according to claim 5, wherein said teaching data forming section searches the boundary point on the basis of a difference value of the pixel data in a boundary region and forms the mask teaching data indicative of the object outline.

10. An apparatus according to claim 5, wherein said teaching data forming section calculates a color mixture ratio in a boundary portion on the basis of an object color and a background color of the target object, searches a boundary point at which a specific color mixture ratio is obtained, and forms the mask teaching data indicative of the object outline.

11. An apparatus according to claim 5, wherein said teaching data forming section overlaps the searched mask teaching data onto the thin-out image data displayed on a display and displays the resultant overlapped data, thereby enabling the operator to monitor an abnormal search.

12. An apparatus according to claim 5, wherein said teaching data forming section has an editing function for correcting the mask teaching data displayed on a display on the basis of an instruction of the operator.

13. An apparatus according to claim 1, wherein a server client system in which said image managing unit is set to a server and said processing unit is set to a client is constructed.

14. An apparatus to claim 13 wherein said client is connected as a workstation to said server by a local area network.

15. A distributed image processing apparatus, comprising:

a data base in which one or a plurality of original shape data indicative of an object shape as a target to form real image data and mask data have been stored;

an image managing unit to manage said data base;

a processing unit connected to said image managing unit through a communication line;

a teaching data forming section within said processing unit for selecting, as mask teaching data, said original shape data adapted to an object as a detection target of an outline in thin-out image data obtained from the real image data in said data base and for notifying to said image managing unit; and

a mask data forming section within said image managing unit for forming mask data indicative of the object outline from the real image data in said data base by using said mask teaching data transferred from said teaching data forming section as a reference.

16. An apparatus according to claim 15, wherein said teaching data forming section overlaps the selected original shape data onto the thin-out image data displayed on a display and displays the resultant overlapped data, thereby allowing an operator to judge an adaptability.

17. An apparatus according to claim 16, wherein said mask data forming section automatically forms the mask data indicative of the object outline with respect to said real image data as a target on the basis of said mask teaching data.

18. An apparatus according to claim 15, wherein a server client system in which said image managing unit is set to a server and said processing unit is set to a client is constructed.

19. An apparatus according to claim 15, wherein said client is connected as a workstation to said server by a local area network.

20. An image processing apparatus, comprising:

a teaching data forming unit forming mask teaching data indicative of an outline of an object from thin-out image data obtained from real image data stored in a data base; and

a mask data forming unit forming mask data indicative of the object outline from said real image data by using said mask teaching data as a reference.

21. An image processing apparatus, comprising:

a data base having one or a plurality of original shape data indicative of a shape of an object as a target to form real image data and mask data;

a teaching data forming unit selecting said original shape data, as mask teaching data, adapted to the object as a target to detect an outline in thin-out image data obtained from the real image data in said data base; and

a mask data forming unit forming mask data indicative of an outline of the object from the real image data of said data base by using said mask teaching data as guidance.

22. A distributed processing system, comprising:

a communications link;

a local processing unit connected to said communications link and allowing a user to designate an initial mask of an image at a first resolution for further processing; and

an image management unit connected to said communications link, providing the image at the first resolution to said local processing unit over said communications link, receiving the initial mask from the local processing unit over said communications link and performing image processing on the image at a second higher resolution.

23. A distributed processing system, comprising:

a communications link;

a local processing unit connected to said communications link and allowing a user to designate an initial mask of an image at a first resolution using shape data; and

an image management unit connected to said communications link, providing the image at the first resolution to said local processing unit over said communications link, receiving the initial mask from the local processing unit over said communications link and performing image processing on the image at a second higher resolution to form a refined mask.
