Two-Point Rectangular Cropping for X-Ray Image Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing x-ray image editing systems face difficulties in restoring a rectangular viewing region after an operator inadvertently converts it into an irregular quadrilateral using the eight-point cropping function.
Innovation Solution
A method is introduced that allows operators to define a viewing region by selecting only two points on the electronic display, which automatically forms a rectangular viewing region, thereby deactivating the eight-point cropping interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the eight-point cropping function is used to adjust the viewing region, then the operator can modify the cropping area, but the rectangle may become an irregular quadrilateral that is difficult to restore to a preferred rectangular shape
Solution Approach 1:
Instead of allowing free dragging of all eight points that may create irregular quadrilaterals, the system inverts the approach by providing a dedicated two-point rectangular cropping mode. This mode uses only two diagonal points to define the rectangle, eliminating the possibility of creating irregular shapes while maintaining cropping functionality.
Solution Approach 2:
The cropping function is segmented into two distinct modes: the traditional eight-point mode for flexible adjustment and a new two-point mode specifically for creating perfect rectangles. This segmentation allows operators to choose the appropriate mode based on their needs, preventing the shape distortion problem in the two-point mode while retaining the flexibility of the eight-point mode.
2Adaptability or versatility
If the eight-point cropping interface is activated, then comprehensive cropping control is available, but the interface complexity increases and operation becomes more time-consuming
Solution Approach 1:
The cropping system provides multi-functionality by incorporating both the eight-point cropping interface and the two-point rectangular cropping interface within the same system. This allows the system to adapt to different operational needs: use the two-point mode for quick rectangular selections and the eight-point mode for complex, irregular cropping requirements.
Solution Approach 2:
For situations where full eight-point control is not needed, the system offers a partial action mode with only two points. This reduces the complexity and time required for operations where simple rectangular cropping suffices, while still providing the option for complete eight-point control when necessary.
3Productivity
If traditional cropping methods are used, then operators can adjust viewing regions, but the process is time-consuming and may require multiple steps to restore rectangular shapes
Solution Approach 1:
The two-point rectangular cropping mode performs preliminary action by directly creating a perfect rectangle in a single operation. This prevents the need for subsequent restoration steps that would be required if the eight-point mode accidentally created an irregular quadrilateral, thereby saving time and improving efficiency.

AI summary
A method of defining a viewing region on an electronic display is performed by selecting only two points on the display and forming the viewing region such that the selected two points are located on a border of the viewing region. The selected two points may be configured to be located at opposite corners of a rectangular viewing region.
