AI Image Cropping Adjusting Human Body Ratio and Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child monitoring systems often select images where the proportion of characters is too small or their position is marginal, leading to potential elimination of content-worthy character bodies and expressions during image processing, as the initial image proportions and positions do not meet user expectations.
Innovation Solution
An image cropping processing method that uses artificial intelligence to calculate a human body area ratio and cropping range, adjusting the image to ensure the character's proportion and position meet user expectations by defining a cropping area that coincides with the human body's focal coordinates, expanding or shifting boundaries as necessary to cover the character fully within the cropping area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If artificial intelligence selects images based on character detection, then image selection automation is improved, but character proportion and position in the selected images deteriorates (too small or marginal)
Solution Approach 1:
The system performs self-adjustment by automatically calculating the human body area ratio and using it to determine the cropping ratio, eliminating the need for manual intervention to achieve proper character proportion and positioning in cropped images
Solution Approach 2:
The patent dynamically adjusts the cropping ratio based on the calculated human body area ratio. By changing the cropping parameters according to the detected character size and position, the system optimizes both automation and image quality simultaneously
2Device complexity
If no artificial processing is applied to selected images, then processing complexity is reduced, but character proportion and position in the images deteriorates (does not meet user expectations)
Solution Approach 1:
The system performs preliminary calculation of the human body area ratio during the selection phase, preparing the necessary data for subsequent cropping operations. This preliminary action enables automatic adjustment without adding complex processing steps later
Solution Approach 2:
The cropping process automatically adjusts character proportion and position by using the pre-calculated human body area ratio to determine the optimal cropping parameters, eliminating the need for manual processing while maintaining high image quality
3Manufacturing precision
If the cropping area is strictly defined by fixed ratios, then cropping precision is improved, but adaptability to different human body areas deteriorates
Solution Approach 1:
The patent makes the cropping ratio a dynamic parameter that changes based on the calculated human body area ratio. This allows the system to maintain precise cropping while adapting to different character sizes and positions in various images
Solution Approach 2:
The system transitions from fixed static cropping ratios to dynamic adjustable ratios that respond to the detected human body area. This dynamic approach enables the cropping parameters to adapt automatically to different scenarios while maintaining precision

AI summary
An image cropping processing method includes calculating a human body area ratio of the human covering area occupying an original size of an initial image, and defining a cropping area in the initial image according to a cropping ratio corresponding to the human body area ratio. Then, coinciding the center points according to the focal coordinate of the human body coverage area and the focal coordinate of the cropping area, and when the human body coverage area is covered within the cropping area in the initial image, the cropping area is selected to crop a cropped image with the proportion and position of the characters that meet the expectations of users. An electronic device of image cropping processing and a non-transitory computer-readable recording medium are utilized to perform the image cropping processing method.
