Description : The dataset was generated using real-world nuclear waste simulants provided by the National Nuclear Laboratory and Sellafield Ltd. UK. Images recorded using the perspective projections of each simulant were distinctly placed on a sorting table for multiple values of ψ and φ. In order to maximise the disparity in object orientation within the training/test sample space, a secondary subsampled dataset is generated from the original set of projections by rotating each image over the angular domain of θ. Each rotated image is further scaled by reducing or increasing by {1.1, ..., 1.5} × original image, which creates a stack of successively smaller and larger images to simulate size variations. Together, they constitute a superset of 86400 subsampled images of training and test data with ground truth annotations from which, in principle, maximally discriminative mappings of 2-D shape projections to distinct class labels can be derived. This dataset further provides the ability to train and test the system in terms of varying object positions and orientations on the sorting table. Collection of data comprising objects at different positions, orientations and locations on the sorting table helps in training and testing the algorithm with anomalies that may arise due to changes in the perspective camera projections of the objects and the resulting effects in their binary silhouettes [Refer to related paper].
