Abstract Change detection of Earth surface using Remote Sensing images is a topic of great interest for studies related to environmental processes. Its execution in a temporal and accurate way is extremely important to understand the interaction relations between anthropic and natural phenomena, allowing the promotion of better decision making. Although a variety of change detection methods have been proposed in the literature, for example, based on simple algebraic operations between images or even supported by spectral transformations or image classification concepts, the use of hypothesis tests for temporal comparisons arise as an attractive way to design new methods of this purpose. In this context, this project focus on the implementation of a change detection algorithm that uses hypothesis testing to distinguish possible conversions on land use and land cover. The proposed method will be applied to analyze changes occurred in São José dos Campos and Jacareí between 1998 and 2018 as result of miner exploiting activities, known as a great agent of environmental degradation in Vale do Paraíba. In order to verify the potential of this new proposal, comparisons with similar techniques already known in the literature will be carried. | |
