Real-Time Image Contour Extraction Without Frame Caching

Solution Overview

Problem

Current image processing systems for smart fitting mirrors require frame caching, leading to increased storage costs, power consumption, and delayed response times due to the need for storing and processing entire image frames, which affects user experience.

Innovation Solution

An image processing method that acquires and processes pixel data in real-time by extracting the contour of a predetermined target within an initial image during transmission, reducing the need for frame caching through preprocessing operations like grayscale conversion, contrast enhancement, and Gaussian filtering, and utilizing intercept parameters to focus on specific regions of interest.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frame caching is used for image processing, then processing completeness is improved, but storage cost increases and response time is delayed

Engineering Contradiction:

Improveprocessing completenessVSAvoidresponse time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts only the necessary contour information of the predetermined target from the complete image frame, rather than processing the entire frame. By using connected domain analysis on binary pixel data, the system extracts minimal essential information (contour coordinates and characteristics) that suffices for application purposes, eliminating the need to cache and process complete frames while maintaining processing reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the image processing task into independent contour extraction operations rather than processing complete frames. By dividing the image into binary pixel data and identifying connected domains corresponding to the target object, the system processes only relevant portions independently, enabling real-time processing without requiring frame caching for completeness.

Inventive Principle:

Principle #1Segmentation

2Reliability

If frame caching is used for image processing, then processing completeness is improved, but power consumption increases

Engineering Contradiction:

Improveprocessing completenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts only the necessary contour information of the predetermined target from the complete image frame, rather than processing the entire frame. By using connected domain analysis on binary pixel data, the system extracts minimal essential information (contour coordinates and characteristics) that suffices for application purposes, eliminating the need to cache and process complete frames while maintaining processing reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by processing only the portion of the image containing the predetermined target rather than the entire frame. Through binary image conversion and connected domain identification, the system performs minimal necessary processing to extract contour information, avoiding excessive processing of irrelevant image areas and thereby reducing power consumption while maintaining sufficient processing completeness.

Inventive Principle:

Principle #16Partial or excessive action

3Loss of information

If entire image frames are processed, then information completeness is improved, but data processing volume increases

Engineering Contradiction:

Improveinformation completenessVSAvoiddata processing volume
