Feature coding has been recently considered to facilitate intelligent video analysis forurban computing. Instead of raw videos, extracted features in the front-end are encoded andtransmitted to the back-end for further processing. In this article, we present a lossless key-pointsequence compression approach for efficient feature coding. The essence of thispredict-and-encode strategy is to eliminate the spatial and temporal redundancies of key pointsin videos. Multiple prediction modes with an adaptive mode selection method are proposed tohandle key-point sequences with various structures and motion. Experimental results validatethe effectiveness of the proposed scheme on four types of widely-used key-point sequences invideo analysis.
