dc.description.abstracten | Change Detection is a critical problem in Computer Vision with applications in various domains such as medical detection, satellite imagery, quality control, and traffic analysis. However, existing change detection models often have many pa- rameters, making them computationally expensive and challenging to implement in real-world applications. This study focuses on reducing the parameters set for the models designed explicitly for Change Detection in Satellite Imagery. These models typically process large-scale images, which can demand significant mem- ory resources and take considerable time to compute. As a solution, we implement three approaches, evaluate and compare their performance on a toy CNN model and an advanced SNUNet-CD model [9], designed for the Change Detection task. The highest parameter reduction rate we achieved for SNUNet-CD is 10.4% (1.25 million parameters) with only a 3.7% model accuracy drop. The experiments demonstrate that, when utilizing our methods, SNUNet-CD outperforms several SOTA models in the change detection domain. We succeeded in surpassing UNet++_MSOF [22] with respect to parameter count, while the original SNUNet-CD with 32 channels was unable to do so.
