Visual Media File Transmission Control for Face Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual media file transmission methods often result in unnecessary data traffic and network resource waste due to the transmission of processed versions of images, which can lead to repeated transmissions of lower quality images, especially in group photos where human faces are blurred, and fail to accurately determine when to send the original version.
Innovation Solution
A visual media file transmission method and user terminal that utilize a transmission control mechanism to analyze the content of the media file, specifically detecting human faces and comparing them to a reference value, to decide whether to send the original or processed version, with the option to prompt the user for confirmation when a certain number of faces are detected, thereby optimizing data transmission and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If processed versions of visual media files are transmitted to reduce data traffic, then network resource efficiency is improved, but image quality deteriorates and repeated transmissions increase
Solution Approach 1:
The system dynamically changes the transmission parameter (file version) based on detected conditions. When human faces are detected in the visual media file, the system switches from transmitting processed versions to transmitting original versions, thereby adapting the transmission quality to the content characteristics and avoiding unnecessary quality loss.
Solution Approach 2:
The system implements a feedback mechanism by analyzing the content of visual media files before transmission. The detection result (whether human faces are present) feeds back into the transmission decision process, allowing the system to adjust its transmission strategy accordingly and avoid transmitting low-quality processed versions when original quality is needed.
2Quantity of substance
If processed versions of visual media files are transmitted to conserve bandwidth, then data traffic is reduced, but the need for repeated transmissions increases
Solution Approach 1:
The system performs preliminary analysis of the visual media file content before transmission to determine whether it contains human faces. This preliminary action allows the system to make an informed transmission decision in advance, selecting the appropriate file version (original or processed) to avoid the need for subsequent retransmissions and saving time.
3Manufacturing precision
If original versions of visual media files are always transmitted to maintain quality, then image quality is preserved, but data traffic and network resource consumption increase
Solution Approach 1:
The system applies different quality levels to different transmission scenarios based on content analysis. When human faces are detected, original quality is transmitted; when no human faces are present, processed quality suffices. This local quality approach ensures high quality is provided only where necessary, reducing overall data traffic while maintaining quality where important.
4Measurement precision
If content analysis of visual media files is performed to determine transmission version, then transmission accuracy is improved, but processing complexity increases
Solution Approach 1:
The system extracts only the critical feature (presence of human faces) from the visual media file for transmission decision-making, rather than performing comprehensive analysis of all file characteristics. This extraction approach improves transmission decision accuracy while keeping processing complexity manageable by focusing only on the most relevant content attribute.

AI summary
Embodiments of the present disclosure provide a visual media file transmission method and a user terminal. The visual media file transmission method includes: monitoring a transmission request for a visual media file; extracting, when the transmission request is detected, according to a reference value, information related to the visual media file to obtain an analysis result. The information related to the visual media file includes content information of the visual media file and/or a communication message associated with the visual media file; and determining, based on the analysis result, whether to transmit an original version of the visual media file. Embodiments of the present disclosure aim at optimizing transmission of the visual media file and lowering the probability of repeated transmission of the visual media file.
