Image Processing Apparatus for Background-Free Material Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to isolate and generate images of materials without backgrounds, leading to differences in the perceived impression of digital content compared to actual printed matter, as background influences affect the captured image.
Innovation Solution
An image processing apparatus that acquires multiple images of a single material with different backgrounds and generates an image of the material without background color using color conversion coefficients, allowing the material image to be displayed with a given background.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an image is captured with a background, then the captured image contains complete visual information, but the background color influences the perceived impression of the content
Solution Approach 1:
The patent extracts the material image from the captured image by separating it from the background. The extraction unit removes the background color information while preserving the material's visual characteristics, creating a standalone material image that can be displayed without background interference. This directly resolves the contradiction by eliminating the harmful background influence while maintaining the完整性 of the material representation.
Solution Approach 2:
The patent segments the captured image into distinct components: the material image and the background. By dividing the image data into these separate elements, the system can process and manipulate them independently, allowing the material to be extracted and reproduced without the interfering background colors, thus improving measurement precision while eliminating harmful background factors.
2Measurement precision
If multiple images with different backgrounds are captured, then the material can be isolated accurately, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by capturing multiple images with different backgrounds before the actual material extraction process. These pre-captured images serve as reference data that facilitate the subsequent extraction process. By preparing this background variation data in advance, the system can more easily isolate the material image without requiring complex real-time processing, thus achieving high isolation accuracy while managing processing complexity.
Solution Approach 2:
The patent uses the multiple background images as intermediary elements in the material extraction process. These background variations act as mediators that help the extraction unit identify and separate the material from its background by comparing how the material appears against different background colors. This intermediary approach simplifies the extraction logic while maintaining high isolation accuracy.
