Image Processing Apparatus Region Growing Segmentation Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems for medical imaging take time to display segmentation results after changing display conditions, reducing usability and increasing storage requirements by storing pixels under various conditions.
Innovation Solution
An image processing apparatus generates a single corrected image and stores it, allowing quick display of segmentation results under changed conditions without re-segmenting, using a region growing method with a variable threshold to extract areas based on pixel luminance, and reduces storage needs by storing only one corrected image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple corrected images are stored for various display conditions, then segmentation results can be displayed quickly under different conditions, but storage capacity requirements increase
Solution Approach 1:
The patent segments the correction process into a one-time preprocessing step that generates a corrected image, which is then stored. During display, the system segments the display conditions into discrete levels and selectively retrieves or reprocesses only the necessary portions of the corrected image, rather than storing complete corrected images for every possible display condition.
Solution Approach 2:
The patent performs preliminary correction of the original image data to generate a corrected image before actual display needs arise. This corrected image is stored and can be efficiently reused across multiple display conditions, eliminating the need for repeated correction processing and reducing storage requirements compared to storing fully processed images for each condition.
2Measurement precision
If segmentation is performed repeatedly when display conditions change, then accurate segmentation results are obtained for each condition, but processing time increases
Solution Approach 1:
The patent performs the computationally intensive correction processing in advance to generate a corrected image that is stored for later use. When display conditions change, the system retrieves the pre-corrected image and applies only minimal condition-specific adjustments, rather than performing complete segmentation and correction processing again, thus maintaining accuracy while significantly reducing processing time.
Solution Approach 2:
The patent implements a dynamic display system that adapts the retrieval and processing strategy based on the specific display conditions. When conditions change, the system dynamically determines whether to retrieve a stored corrected image or perform minimal reprocessing, optimizing the balance between segmentation accuracy and processing speed for each specific scenario.

AI summary
An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry sets a reference position in an area extracted by performing first processing on first image data. The processing circuitry sets a processing condition based on a pixel value at the reference position. The processing circuitry changes a threshold included in the processing condition in stages and performs second processing for extracting an area corresponding to the threshold on the first image data at each stage, thereby generating second image data including a result of the second processing at each stage.
