Abstract
En 中文
Traditional change detectors are ill-equipped for incremental learning (IL). Existing IL methods address the problem of catastrophic forgetting by artificially adding categories and utilizing old labels for learning supervision. Current strategies for change detection (CD) are inadequate as they fail to address a crucial aspect of the task: the constant label space throughout each training step, causing label conflicts between background-class pixels (representing unchanged regions) and changed pixels, which can lead to knowledge confusion. In this work, we revisit classical IL methods and propose an effective framework that explicitly addresses this conflict. Furthermore, we design a hierarchical distillation to ensure adequate retention of the learned features. The proposed architecture and distillation method balance acquiring new knowledge and preserving old knowledge effectively. To address the absence of datasets for IL in CD, we design a multidomain CD dataset that encompasses three distinct environments. Our proposed method demonstrates a significant improvement in the performance of IL, as measured by Delta(IoU) and Delta(F1) . Extensive experiments on this dataset show that our performance is promising compared to state-of-the-art CD methods and incremental methods.
