Keypoint encoding and transmission for improved feature extraction from compressed images

Chao, Jianshu; Steinbach, Echehard; Xie, Lexing

Description

In many mobile visual analysis scenarios, compressed images are transmitted over a communication network for analysis at a server. Often, the processing at the server includes some form of feature extraction and matching. Image compression has been shown to have an adverse effect on feature matching performance. To address this issue, we propose to signal the feature keypoints as side information to the server, and extract only the feature descriptors from the compressed images. To this end, we...[Show more]
