change detection的基本任务:用进程内的状态(Component中的数据)来更新view(DOM)的显示。 Angular Change Detection发生的时机:基本上所有的异步事件发生(并且回调函数已经执行完毕...

Change detection (CD)

• multispectral satellite images
  • exploit the spectral information in bitemporal images
    • change vector analysis (CVA)
    • principal component analysis (PCA)
• high-resolution(HR) images
  • same resolution properties
    • traditional CD methods
  • different resolutions
    • simply down-sample the HR image to the resolution of the LR image
    • interpolate the LR image to the resolution of the HR image
    • the subpixel-based method
      • Ling et al. [26] first introduced subpixel mapping (SPM) to CD
      • Wang et al. [27] proposed a Hopfield neural network with SPM
      • Li et al. [28] applied an iterative super-resolution CD method for Landsat-MODIS CD, which combines end-member estimation, spectral unmixing, andSPM
      • Wu et al. [29] proposed a back propagation neural network to obtain subpixel LCC maps from the soft-classification results of LR images
    • end-to-end super-resolution-based change detection network (SRCDNet)
