Change detection using remotely sensed images has many applications such as urban monitoring land-cover change analysis and disaster management. This work investigates two-dimensional change detection methods. The existing methods in the literature are grouped into four categories: pixel-based transformation-based texture analysis-based and structure-based. In addition to testing existing methods four new change detection methods are introduced: fuzzy logic-based shadow detection-based local feature-based and bipartite graph matching-based. The latter two methods form the basis for a structural analysis of change detection. Three thresholding algorithms are compared and their effects on the performance of change detection methods are measured. These tests on existing and novel change detection methods make use of a total of 35 panchromatic and multi-spectral Ikonos image sets. Quantitative test results and their interpretations are provided.
