dc.description.abstractScene change detection helps to detect changes in a pair of multitemporal images of the same scene. We apply the concept of scene change detection to detect misplaced objects in a passenger vehicle. Deep learning neural networks have been extensively used in scene change detection. We study scene change detection using the classical Watershed algorithm and machine learning algorithms. In machine learning, we exploit the feature extraction capability of ResNet and Spatial Pyramid Pooling to predict the scene change. The performance of the classical and machine learning algorithms are also compared. The models are trained on a custom dataset and evaluated using the metrics, dice coefficient, mean intersection over union (mIoU) and pixel accuracy. We infer that the machine learning model significantly outperforms the classical model in terms of mIoU
