Image Nose Area Enhancement via Localized Brightness Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to enhance images of faces to make them appear more lifelike, particularly focusing on the nose area, as users share images and desire a more realistic representation.
Innovation Solution
A computing device method that defines the nose area within an image by highlighting and shading regions and adjusts brightness using a processor to create an enhanced image, increasing the brightness of the highlighted region and decreasing it in the shaded regions, thereby creating a more three-dimensional effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If brightness adjustment is applied to the entire face, then the overall image quality improves, but the three-dimensional effect of the nose area is not sufficiently enhanced
Solution Approach 1:
The patent applies different brightness adjustment strategies to different regions of the nose area. The highlighted region (middle of nose) has its brightness increased, while the shaded regions (left and right sides bordering the nose) have their brightness decreased. This localized differential adjustment creates a three-dimensional effect that uniform brightness adjustment cannot achieve.
2Manufacturing precision
If complex image processing algorithms are used, then the enhancement quality improves, but the processing time and computational resources increase
Solution Approach 1:
The nose area is segmented into three distinct regions: a highlighted region corresponding to the middle of the nose, a first shaded region on the left side bordering the nose, and a second shaded region on the right side bordering the nose. This segmentation allows for targeted brightness adjustments in each region, achieving high enhancement quality through simple brightness manipulation rather than complex algorithms.

AI summary
A method of enhancing a nose area of an image containing a face with a nose visible on the face includes loading the image into a computing device having a processor. The processor defines the nose area on the image, the nose area including a highlighted region corresponding to a middle of the nose, a first shaded region being located on a left side of the nose and bordering the left side of the nose, and a second shaded region being located on a right side of the nose and bordering the right side of the nose. The processor next performs an image enhancement process on the image to create an enhanced image, the image enhancement process including increasing the brightness of the highlighted region and decreasing the brightness of the first shaded region and the second shaded region. The processor then outputs the enhanced image.
