    Application of Discrete Mathematical Model in Edge Distortion Correction of Moving Image by Qingwei Xu, Zhoufeng Liu

    Published 2022-01-01
    “…Therefore, this study proposes an edge distortion correction method of moving images using a discrete mathematical model. According to the image binarization, the moving target region is segmented, the motion fuzzy degradation model is constructed by using the discrete mathematical model, the global structure information of the image is considered by the structure similarity, the image gradient is transformed from the rectangular coordinate system to the polar coordinate system, the image deconvolution algorithm of the edge distribution of the natural image is used to enhance the image edge features, and the edge distortion correction of the moving image is realized. …”

    Discrete Coupling and Synchronization in the Insulin Release in the Mathematical Model of the β Cells by L. J. Ontañón-García, E. Campos-Cantón

    Published 2013-01-01
    “…The aim of this work is to generate in-phase bursting electrical activity (BEA) in β cells with different behaviors such as active, inactive, and continuous spiking cells based on mathematical models using a discrete time coupling. The approach considers two steps, the former is a mechanism on how to force β cells to switch from silent phase to active, the latter is based on how to deal with in phase synchronization between active β cells. …”
