Solution Overview

Problem

Public safety personnel face challenges in quickly and accurately locating objects of interest in large or crowded areas, as existing methods using multi-object classifiers are computationally complex and time-consuming, while single object classifiers require multiple instances and post-filtering processes, leading to inefficiencies.

Innovation Solution

A method utilizing a single object classifier on a mobile media device that determines a hue saturation value range and detects macroblocks associated with the object of interest, completing classification when a threshold of pixels within that range is exceeded, allowing for efficient detection without reloading the classifier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multi-object classifiers are used to locate objects of interest, then detection accuracy is improved, but computational complexity and processing time increase significantly

Engineering Contradiction:
Improvedetection accuracyVSAvoidcomputational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the detection process into two stages: first using a lightweight single object classifier to quickly identify potential regions, then applying more sophisticated analysis only to those specific regions. This segmentation allows the system to achieve high detection accuracy through the single object classifier while avoiding the computational burden of applying multi-object classifiers to entire images, thus resolving the contradiction between detection accuracy and computational complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by using a simplified single object classifier for initial detection rather than the full multi-object classification process. This partial approach is sufficient for the initial screening phase, and only when needed does the system engage in more extensive analysis. This allows the system to achieve acceptable detection accuracy with significantly reduced computational complexity.

Inventive Principle:
Principle #16Partial or excessive action

2Adaptability or versatility

If multiple single object classifiers are used to detect different objects, then detection coverage is improved, but device complexity and processing time increase

Engineering Contradiction:
Improvedetection coverageVSAvoidnumber of classifier instances
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the single object classifier universal by training it to detect multiple types of objects of interest (suspects, missing persons, stolen vehicles) using a unified detection framework. Rather than deploying separate specialized classifiers for each object type, the single classifier performs multiple functions through color-based detection and region analysis, thereby improving detection coverage while reducing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes detection parameters (such as color thresholds, saturation levels, and region boundaries) to adapt the single object classifier for different object types and scenarios. By dynamically adjusting these parameters rather than using multiple fixed classifiers, the system achieves versatile detection coverage with a single adaptable classifier instance, reducing overall system complexity.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If post-filtering is applied to single object classifier results, then detection precision is improved, but processing time increases

Engineering Contradiction:
Improvedetection precisionVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges the single object classifier detection process with color-based region analysis and saturation threshold filtering into a unified detection pipeline. By combining these functions into a single integrated process rather than sequential steps (classification followed by post-filtering), the system achieves improved detection precision through color verification while minimizing additional processing time through efficient integrated execution.

Inventive Principle:
Principle #5Merging (Combining)
