FIG. 1 is a system configuration diagram schematically illustrating an outline processing apparatus for enhancing recognition of a character according to a preferred embodiment of the present invention.

1, the contour processing apparatus according to the present invention includes a resolution managing unit 10 for extracting and managing resolution information of a device to be applied, a character selecting unit 20 for providing an interface for selecting a character , An outline processing determination unit 30 for analyzing the selected character and the resolution information extracted through the resolution management unit to determine whether or not the outline processing is necessary and the expansion processing and erosion processing for the character when it is determined that the outline processing is necessary And an outline processing unit 40 for extracting and applying an optimal outline line through the outline processing unit 40 .

The resolution managing unit 10 can directly extract resolution information by parsing the resolution information of the device to be applied, and the resolution of the device to be applied can be extracted by receiving the resolution information from the user.

In general, characters are manufactured to be optimized to a specific resolution because they are produced by a graphic tool. Therefore, it is necessary to process the contour line to improve the character recognition according to the resolution of the device to be applied.

The character selection unit 20 provides an interface that allows a character requiring a contour processing to be selected from a character DB that stores and manages characters.

The contour processing determination unit 30 determines the resolution information of the device to be applied extracted from the resolution management unit and the character selected from the character selection unit to determine whether contour processing is necessary.

Here, the character selected from the character selection unit 20 may include character information, and the character information may include the optimum resolution information on which the character is manufactured.

Accordingly, the outline processing determination unit 30 can determine whether or not the outline processing is necessary by comparing the resolution information and the resolution information included in the character information.

That is, if the resolution information included in the character information is higher than or equal to the resolution information of the device extracted through the resolution managing unit, contour processing is not required. However, when the resolution information included in the character information is low, need.

The contour processing determination unit 30 may include a simulation module for outputting the character according to the extracted resolution when character information is not included in the character, and a contour processing unit for determining whether contour processing is required for the character output through the simulation module And a judgment module for judging the judgment result.

The simulation module allows the character to simulate the output at a specified resolution, thereby determining whether contour processing is required.

For example, when a character is output at a resolution designated by the simulation module and the outline is boiled or the thickness of the line is blurred below a predetermined thickness, it is determined that the outline processing is necessary because the determination module is in a poor state do.

In this case, the criterion for determining whether or not the contour processing is required by the determination module may be set differently according to the resolution, and it is determined that contour processing is necessary when the outline of the character is disconnected and the thickness of the outline is less than the reference thickness .

Here, the reference thickness may be set differently for each resolution. When the resolution is high, the reference thickness is low, and when the resolution is low, the reference thickness is high .

The contour processing unit 40 extracts the contour line through the difference of the operation obtained through the inflating operation and the expansion operation of the input character.

The contour processing unit includes an expansion operation module 410 for performing an expansion operation on a character image, an erosion operation module 420 for performing an erosion operation on a character image, and an erosion operation module 420, And an outline extraction module 430 for extracting an outline through a difference in operation.

FIG. 2 schematically illustrates an expansion calculation process and an erosion calculation process. FIG. 3 schematically shows a process of extracting an outline through an expansion calculation and an erosion calculation according to a preferred embodiment of the present invention.

2 and 3, the expansion computation module 410 binarizes the input character image, composes the morpheme (mask) of the expansion computation to all zeros, and then lines the mask to the input character, If the values of the characters are the same, replace them with 0. If at least one does not match, replace them with 1 to perform the expansion operation.

The erosion operation module 420 binarizes the input character image and composes the morpheme (mask) of the expansion operation to 1, then lines the mask to the input character, and if the value of the morpheme is equal to the value of the input character, , And when at least one of them is inconsistent, the erosion operation is performed by replacing with 0.

The outline extraction module 430 extracts the outline through the difference between the expansion operation through the expansion operation module and the erosion operation through the erosion operation module.

Here, the outline extraction module 430 extracts the optimized outline thickness through repetition of the expansion and erosion operations and applies it to the character .

FIG. 4 shows improved recognition of a character according to contour processing according to a preferred embodiment of the present invention.

As can be seen from FIG. 4, the present invention improves the recognition performance by extracting and applying the outline line of the optimal thickness according to the resolution of the device.

Hereinafter, a contour processing method for enhancing the recognizability of a character according to the present invention will be described.

5 is a flowchart schematically showing a contour processing method according to a preferred embodiment of the present invention.

Referring to FIG. 5, the resolution manager extracts the resolution of the applied device.

The resolution managing unit may extract resolution information by parsing the resolution information through the controller of the device when the resolution managing unit is directly connected to the device to be applied, and may extract the resolution information by receiving the resolution of the device to be applied from the user.

The resolution managing unit may further include a resolution information table to which resolution information of each application device is mapped if the user does not know the resolution information. The resolution managing unit may specify the application device through the resolution information table to the user, Interface.

Then, the user selects a desired character through the character selecting unit.

The character can be called from an internal or external character DB, and the character selecting unit can provide an interface through which a user can select a desired character.

If the character is selected, the outline processing determination unit analyzes the resolution information and the selected character to determine whether or not the outline processing is necessary.

When the character information including the resolution information generated in the selected character is included, the contour processing determination unit compares the resolution information of the device with the resolution information of the character to determine whether contour processing is necessary.

If there is no outline information, the simulation module of the outline processing determination unit simulates the character with the resolution information condition of the device, and the determination module determines whether or not the outline processing is necessary through the simulation result.

The contour processing requirement can be judged based on whether or not the outline has a single line and whether the outline thickness is smaller than the reference thickness of the resolution .

If the outline processing determination unit determines that the outline processing is necessary, the outline processing unit performs the outline processing on the character.

In contour processing, the expansion and erosion operations are performed on the character input through the expansion operation module and the erosion operation module, and the outline extraction module extracts the outline through the difference of the operation obtained as a result.

The outline extraction module analyzes the thickness of the extracted outline to determine whether it is an optimal thickness. If the outline is not the optimum thickness, the outline extraction module repeats the calculation to extract the outline of the optimal outline.

Here, the determination of the optimum thickness may be performed by comparing the reference thickness with a preset reference thickness, and the character applied the outline drawn through the simulation module may be analyzed to determine whether it is the optimum thickness .

When the outline is extracted as described above, the outline is applied to the character to complete the outline processing.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
