    Preprocessing and authentication of 2D barcodes by Chen, Changsheng.

    Published 2013
    “…In this thesis, we investigate the detection step of a barcode by modeling its finder pattern as a 2D signal with finite rate of innovations and reconstructing it through block by block operation. Then, a quality checking step of the barcode images is added to reject those poor quality images for saving the time in processing the undecodable images and avoiding wrongly decoded information. …”

    Triangular angle rigidity for distributed localization in 2D by Chen, Liangming

    Published 2022
    “…More importantly, inspired by Laman's theorem, we propose a topological, necessary and sufficient condition to check generic triangular angle rigidity. Based on the results on triangular angle rigidity, both algebraic and topological localizability conditions are developed, which are necessary and sufficient when the number of anchor nodes in the network is two. …”
