Document Image Verification via Specific Character Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image search techniques require users to open and display document files to determine the presence of specific images, such as seals, which is time-consuming and labor-intensive.
Innovation Solution
An information processing apparatus that identifies the type of document, extracts specific character information associated with the image, and determines the presence of a specific image by matching search conditions, allowing for the detection of seals within documents without opening the file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user opens a document file to determine whether a specific image is contained in the document, then the user can visually verify the presence of the image, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent extracts the specific image from the document and displays it separately on the display unit. This allows the user to verify the presence of the image without opening the entire document file, thereby reducing the time required while maintaining verification accuracy
Solution Approach 2:
The patent creates a copy of the specific image from the document and displays this copy on the display unit. The copy contains identification information that allows verification without accessing the original document file, thus saving time while preserving verification capability
2Productivity
If the system automatically extracts and displays specific images from documents, then the time and effort required for verification is reduced, but the system complexity increases
Solution Approach 1:
The patent performs preliminary extraction of specific images and their identification information before the user needs to verify them. The system pre-processes the document to identify and separate the target image, making verification ready-to-go and significantly improving efficiency
Solution Approach 2:
The patent introduces an intermediary display unit that shows the extracted image and its identification information. This intermediary layer mediates between the document and the user, providing verification capability without requiring direct document access, thus managing system complexity

AI summary
An information processing apparatus includes a processor. The processor is configured to identify a type of a target document to be processed from a read image obtained by reading the target document; refer to specific-character information, the specific-character information being information on a specific character set for each type of document in association with a specific image that is to be contained in the document, to obtain a specific character corresponding to the type of the target document and associated with a specific image that is to be contained in the target document; and determine whether an image that matches a search condition set in advance for the obtained specific character is extractable from the read image, to determine a presence or absence of a specific image that is to be contained in the target document in association with the obtained specific character.
