Abstract: In the baggage image database captured by the self-service baggage check-in system, the image background seriously affects the retrieval accuracy of wrongly transported baggage. To solve this problem, a super-pixel segmentation method based on Enhanced Fuzzy C-Means Clustering Method (EnFCM) is proposed to extract the target baggage area. Through multi-scale morphological reconstruction of gradient images, an adaptive upper scale watershed super-pixel pre-segmentation algorithm is designed to obtain multiple independent super-pixel regions. Based on the histogram statistics of the super-pixel image, combined with the watershed segmentation parameters and the number of categories of the actual baggage image content, the EnFCM segmentation is conducted to extract the baggage area. The segmentation experiments of several real baggage images verify the effectiveness of the algorithm with the average segmentation accuracy reaching 93%, surpassing that of several typical segmentation algorithms.
