Cloud Desktop Image Transmission via Similarity Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cloud desktop protocol experiences low efficiency in image transmission due to high network bandwidth usage and delayed image display, as images are transmitted from the cloud terminal to the cloud desktop and back, which does not improve network concurrency or server load.
Innovation Solution
An image transmission method that calculates the similarity between captured images and a reference image, selecting and transmitting only the image with the minimum similarity, thereby reducing data transmission bandwidth requirements and ensuring clear display on the cloud terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If local backhaul technology is used to directly display images locally on the cloud terminal, then image display efficiency is improved, but network bandwidth is much occupied and server load is not reduced
Solution Approach 1:
The patent changes the transmission parameter from transmitting all captured images to transmitting only selected images based on similarity calculation. By calculating similarity between consecutive images and selecting only those exceeding a threshold, the system reduces transmission quantity while maintaining display quality, thus resolving the bandwidth consumption issue while preserving image display efficiency.
Solution Approach 2:
The patent extracts only the essential information (images with significant changes) from the complete image stream and transmits only these extracted images to the cloud desktop. This extraction principle filters out redundant identical images, reducing network bandwidth occupation while maintaining the core functionality of image display.
2Loss of information
If all captured images are transmitted to the cloud desktop, then complete image data is available, but data transmission bandwidth is excessively consumed
Solution Approach 1:
The patent introduces a similarity threshold parameter to control image transmission selection. By comparing each captured image with the previous one and only transmitting images that exceed the threshold, the system maintains essential image data while significantly reducing transmission bandwidth consumption.
Solution Approach 2:
Instead of transmitting all images (excessive action), the patent transmits only the necessary subset of images that contain meaningful changes (partial action). This partial transmission approach suffices for maintaining image data completeness while avoiding excessive bandwidth consumption.
3Extent of automation
If image transmission path is extended from cloud terminal to cloud desktop and back, then cloud processing is achieved, but transmission efficiency is low causing delay
Solution Approach 1:
The patent extracts only the essential changed image data for cloud transmission, reducing the volume of data that needs to traverse the extended path. This extraction minimizes the time loss associated with the round-trip transmission while preserving cloud processing capabilities.

AI summary
Embodiments relate to the field of computers, and provide a method for transmitting an image, a terminal and a storage medium. The method for transmitting an image comprises: obtaining N images acquired by an image acquisition device, wherein N is a positive integer greater than or equal to 1; respectively calculating the similarities of the N images and a reference image, the reference image being a locally stored image that is last sent to a cloud desktop; selecting one image from the N images as an image to be transmitted according to the similarities of the N images and the reference image; and sending the image to be transmitted to the cloud desktop.
