Information processing apparatus for character recognition and non-transitory computer readable medium
An information processing apparatus includes a character recognition unit that performs a character recognition process to recognize a character included in an image, and a partitioning unit that partitions a specific region if a character string recognized through the character recognition process performed by the character recognition unit on a specific region included in the image includes a character or a character string, each of which satisfies a predetermined condition.
1. An information processing apparatus comprising:
a controller configured to:
perform a character recognition process to recognize a character included in an image; and
partition a specific region if a character string recognized through the character recognition process on the specific region included in the image includes a character or a character string, each of which satisfies a predetermined condition, wherein
the specific region is a region corresponding to a partial image contained in the image or a region corresponding to the image as a whole,
the predetermined condition is a condition where a character having a predetermined out-of-range size is included in the character string recognized from the specific region,
the controller is configured to partition the specific region if the predetermined condition is satisfied.
2. The information processing apparatus according to claim 1 , wherein the controller is configured to detect, as the character having the predetermined out-of-range size, a character having an out-of-range size identified by a second predetermined index value that is predetermined by a first predetermined index value.
3. The information processing apparatus according to claim 2 , wherein the controller is configured to detect the character having the out-of-range size identified by a mean value and a standard deviation, and wherein the first index value is the mean value of sizes of characters included in the image, and wherein the second index value is the standard deviation of the sizes of the characters.
4. The information processing apparatus according to claim 3 , wherein the controller is configured to partition the specific region if the predetermined condition that the character string recognized from the specific region includes a character string including a predetermined arrangement is satisfied.
5. The information processing apparatus according to claim 4 , wherein the controller is configured to separate a character string included in the character string recognized from the specific region into partial character strings, each partial character string having a predetermined unit,
wherein the controller is configured to partition the specific region if the partial character string includes a character string including the predetermined arrangement.
6. The information processing apparatus according to claim 2 , wherein the controller is configured to partition the specific region if the predetermined condition that the character string recognized from the specific region includes a character string including a predetermined arrangement is satisfied.
7. The information processing apparatus according to claim 6 , wherein the controller is configured to separate a character string included in the character string recognized from the specific region into partial character strings, each partial character string having a predetermined unit,
wherein the controller is configured to partition the specific region if the partial character string includes a character string including the predetermined arrangement.
8. The information processing apparatus according to claim 1 , wherein the controller is configured to partition the specific region if the predetermined condition that the character string recognized from the specific region includes a character string including a predetermined arrangement is satisfied.
9. The information processing apparatus according to claim 8 , wherein the controller is configured to separate a character string included in the character string recognized from the specific region into partial character strings, each partial character string having a predetermined unit,
wherein the controller is configured to partition the specific region if the partial character string includes a character string including the predetermined arrangement.
10. The information processing apparatus according to claim 9 , wherein the controller is configured to separate, into the partial character strings, a character string included in the character string recognized from the specific region, by performing N-gram or morphological analysis.
11. The information processing apparatus according to claim 8 , wherein the controller is configured to convert a first character forming the character string included in the specific region into a second character.
12. The information processing apparatus according to claim 1 , wherein if the specific region is partitioned into a plurality of regions, the controller is configured to perform the character recognition process on the partitioned regions.
13. The information processing apparatus according to claim 1 , wherein the controller is configured to partition the specific region in response to an operation performed by an operator.
14. The information processing apparatus according to claim 1 , wherein the controller is configured to partition the specific region if the predetermined condition that the character having a predetermined out-of-range size is included in the character string recognized from the specific region is satisfied and the predetermined condition that the character string includes a character string including a predetermined arrangement is satisfied.
15. The information processing apparatus according to claim 1 , wherein the controller is configured to partition the image into the specific region in advance in accordance with a frequency distribution of pixels of the image.
16. A non-transitory computer readable medium storing a program causing a computer to execute a process for processing information, the process comprising:
performing a character recognition process to recognize a character included in an image; and
partitioning a specific region if a character string recognized through the character recognition process performed on the specific region includes a character or a character string, each of which satisfies a predetermined condition, wherein
the specific region is a region corresponding to a partial image contained in the image or a region corresponding to the image as a whole,
the predetermined condition is a condition where a character having a predetermined out-of-range size is included in the character string recognized from the specific region,
the specific region is partitioned if the predetermined condition is satisfied.
