Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current image processing technologies for mobile devices are limited in enhancing facial features beyond eyes, nose, and face shape, failing to achieve an ideal beautification or funny distortion effect for users.

Innovation Solution

An image processing method and apparatus that detects key points in a face image, determines a target region for malar fat pad adjustment, and adjusts this region based on specific parameters to generate a second face image, allowing for beautification or funny distortion of the malar fat pad region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If image processing is limited to eyes, nose, and face shape, then processing complexity is reduced, but beautification effect is insufficient

Engineering Contradiction:

Improveprocessing complexityVSAvoidbeautification effect

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent segments the face into multiple distinct regions including malar fat pads, eyes, nose, lips, and chin. Each region is processed independently with region-specific adjustment parameters, allowing comprehensive beautification without overwhelming complexity. The malar fat pad region is specifically segmented and targeted for adjustment based on detected key points.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by using different processing strategies for different facial regions. The malar fat pad region receives specific adjustment treatment distinct from other regions like eyes, nose, or lips. Each region has its own adjustment parameters and processing intensity, enabling precise local beautification while maintaining overall face harmony.

Inventive Principle:

Principle #3Local quality

2Manufacturing precision

If malar fat pad region adjustment is added to image processing, then beautification effect is improved, but processing complexity increases

Engineering Contradiction:

Improvebeautification effectVSAvoidprocessing complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary action by detecting key points of the face and pre-determining the malar fat pad region before applying adjustment parameters. This preliminary segmentation and identification of the target region simplifies the subsequent processing by establishing clear boundaries and reference points, reducing the complexity of the actual adjustment operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses parameter changes by adjusting specific parameters of the malar fat pad region such as position, size, and shape based on detected key points. The adjustment parameters are calculated and applied systematically, transforming the original region coordinates and dimensions to achieve the desired beautification effect while maintaining processing efficiency through mathematical transformations.

Inventive Principle:

Principle #35Parameter changes
