Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current contact management solutions lack effective tools for capturing and presenting cohesive, high-quality multiple facial photos that represent different view angles and personal expressions, leading to inconsistent and non-representative images in personal and professional contexts.
Innovation Solution
A method that involves obtaining an initial set of facial photographs, removing low-quality images, grouping and filtering by view angle, and selecting an optimal subset based on facial expressions using software for automatic detection and user review, ensuring diversity and closeness to ideal prototypes in a multi-dimensional space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple contact photos are collected from social networking sites or sporadic personal photos, then the quantity of contact photos increases, but the consistency and representativeness of images deteriorates due to significant variations in size, image quality and lack consistency
Solution Approach 1:
The patent segments the photo selection process into multiple filtering stages: initial quality assessment, view angle classification, expression analysis, and final selection. This segmentation allows systematic processing of large quantities of photos while maintaining consistency criteria at each stage, resolving the contradiction between quantity and quality.
Solution Approach 2:
The patent changes multiple parameters simultaneously including image resolution thresholds, view angle ranges (front, profile, 3/4 views), lighting conditions, and facial expression categories. By establishing specific parameter ranges for each selection criterion, the system maintains manufacturing precision while processing large quantities of photos from various sources.
2Manufacturing precision
If instructional UI working with device sensors is used to optimize view angle, then the quality of captured facial photos improves, but the complexity of the capturing process increases
Solution Approach 1:
The system performs self-service by automatically analyzing captured photos through software that detects facial expressions, determines view angles, and selects optimal images without requiring manual user intervention. The software autonomously evaluates lighting conditions, image quality, and composition, reducing the perceived complexity for users while maintaining high manufacturing precision.
Solution Approach 2:
The patent replaces manual mechanical adjustment of camera angles and positions with software-based automated selection. Instead of requiring users to physically adjust devices to achieve optimal angles, the system captures multiple photos at various angles and uses software algorithms to automatically select the best ones, substituting mechanical complexity with computational simplicity.
3Productivity
If software automatically detects facial expressions and selects optimal photos, then the productivity of photo selection increases, but the difficulty of detecting and measuring accurate facial expressions and angles increases
Solution Approach 1:
The software segments the complex detection task into distinct modules: one module detects facial features and landmarks, another analyzes facial expressions by evaluating muscle movements and facial geometry, and a third determines view angles by analyzing the orientation of detected features. This segmentation reduces the difficulty of each individual detection task while maintaining high overall productivity through automated processing.

AI summary
Extracting an optimal subset of facial photographs includes obtaining an initial set of facial photographs, removing from the initial set photographs any photographs that are of unacceptable quality, grouping a remaining set of photographs according to view angle, removing from the remaining set of photographs any photographs having an undesirable facial expression to provide a limited set of representative facial photographs, and, selecting, from the limited set of facial photographs, an optimal subset of facial photographs. Obtaining the initial set of photographs may include using a video camera while diversifying view angles and controlling recording quality. Obtaining the initial set of photographs may include obtaining a series of still images. The still images may be self-recorded by a person with a smartphone front-facing camera.
