Abstract

A method, system and computer program for defining a geometric code is provided. The method for generating a geometric code includes the steps of defining a first geometric shape, defining a size of a second geometric shape as a change in size from the first geometric shape, defining a position of the second geometric shape as a change in position from the first geometric shape, and displaying the first geometric shape and the second geometric shape. A system for imaging the defined geometric code includes a processor performing the steps of segmenting the imaged code, partitioning the segmented imaged code, determining a gray level of each portion of the partitioned segmented imaged code, and determining a code represented by each segmented portion of the partitioned segmented imaged code.

Claims

1. A system for reading a code from an object, comprising:

an imaging apparatus for imaging a code printed to an object, the code being defined by defining a first geometric shape, defining a size of a second geometric shape as a reduction in size from the first geometric shape, defining a position of the second geometric shape within the first geometric shape as a change in position from the first geometric shape, defining a size of a third geometric shape as a reduction in size from the second geometric shape, defining a position of the third geometric shape within the second geometric shape as a change in position from the second geometric shape;

a processor for processing the imaged code, the processor segmenting the imaged code, partitioning the segmented imaged code, determining a gray level of each portion of the partitioned segmented imaged code, and determining a code represented by each segmented portion of the partitioned segmented imaged code.

2. The system of claim 1, wherein the processor further verifies that the determined code is a valid code by confirming that the determined code meets a predefined set of constraints.

3. The system of claim 2, wherein the processor further matches the determined code to one of a plurality of possible codes.

4. The system of claim 1, wherein the object on which the code is imprinted is a medication tablet.

5. The system of claim 1, wherein each portion of the partitioned segmented imaged code comprises a predetermined grid having a predetermined length and width.

6. A non-transient computer readable storage medium having a computer program stored thereon, the computer program causing a general purpose computer to perform the steps of:

receiving an imaged code from an imaging device;

segmenting the imaged code;

partitioning the segmented imaged code into four quadrants;

determining a gray level of each portion of the partitioned imaged segmented code;

determining a code represented by each segmented portion of the partitioned imaged segmented code;

verifying that the determined code is a valid code by confirming that the recovered determined code meets a predefined set of constraints; and

matching the determined code to one of a plurality of possible codes.

7. The computer readable storage medium of claim 6, wherein two diagonally positioned quadrants contain a similar code stored therein.

8. The computer readable storage medium of claim 6, wherein the portions of the partitioned imaged segmented code are defined by a grid overlaid thereon.

9. A non-transient computer readable storage medium having a computer program stored thereon, the computer program causing a general purpose computer to perform the steps of:

receiving an imaged code from an imaging device;

segmenting the imaged code;

partitioning the segmented imaged code;

determining a gray level of each portion of the partitioned imaged segmented code;

determining a code represented by each segmented portion of the partitioned imaged segmented code;

verifying that the determined code is a valid code by confirming that the determined code meets a predefined set of constraints; and

matching the determined code to one of a plurality of possible codes;

wherein the step of determining a gray level of each portion of the partitioned segmented imaged code further comprises the steps of;

counting a number of colored pixels in the portion of the partitioned imaged segmented code;

determining a ratio of colored to non-colored pixels in the portion of the partitioned imaged segmented code; and

comparing the determined ratio to a predetermined threshold to determine whether the portion of the partitioned segmented imaged code is a colored portion.
