Surveillance Mask Processing for Action Tendency Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems struggle to efficiently analyze and output the action tendencies of individuals in a store's surveillance footage for marketing analysis and service improvement, lacking effective methods to differentiate and track individual actions over time.
Innovation Solution
A monitoring apparatus that uses a processor to detect individuals in surveillance footage, perform mask processing by converting their outlines into translucent images, and superpose these mask images onto a background, generating a mask-processed moving image for efficient analysis and output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image area of the person is replaced with a specific image to easily discriminate between the background and the person, then the ease of grasping the action of the person is improved, but the ability to efficiently perform operation of grasping the action tendency of the person deteriorates
Solution Approach 1:
The patent applies color changes by using different colors for mask images representing different persons. This allows the system to maintain clear discrimination between persons and background while enabling efficient analysis of action tendencies through color-coded identification. The color differentiation enables both immediate visual distinction and systematic analysis of individual behaviors over time.
2Measurement precision
If the entire person area is changed to a mask image, then the discrimination between background and person is improved, but the detail information of the person is lost
Solution Approach 1:
The patent applies local quality by creating mask images that cover only the necessary portions of the person while preserving key identifying features. The mask processing selectively obscures certain areas while maintaining others, allowing the system to achieve adequate discrimination without completely losing person detail information. This selective masking enables both privacy protection and actionable analysis.

AI summary
A monitoring apparatus includes a processor, wherein the monitoring apparatus images a monitoring area and outputs a moving image of the monitoring area, and the processor detects all persons appearing in the moving image, performs mask processing of changing inner portions of outlines of all persons into translucent mask images, and superposes the mask images on a background image, to generate a mask-processed moving image, and outputs the mask-processed moving image to a browsing apparatus through a network.
