OBJECTIVE: Develop a synthetic imagery dataset of Unmanned Aerial Systems (UAS) using machine learning (ML) for computer vision discriminator applications. DESCRIPTION: Unmanned Aerial Systems (UAS) pose a threat to the US Navy (USN) surface fleet. Counter-UAS results in successful negation of UAS threats by USN effectors. It requires the ability to detect, identify, discriminate, and engage in a cost-effective manner. In order to increase the automation of surface sensors' ability to detect, identify, and discriminate UAS, large data sets of image and video data must be collected. The number and variety of UAS and the need for all aspect coverage make physical data collections costly in terms of time and money. The USN seeks automated visual synthetic data generation using ML to develop these large data sets. The produced data sets will train algorithms. Synthetic data generation is a rapidly growing field. It is being applied to many different use cases including autonomous vehicle navigation and advanced driver-assistance systems as well as security systems and manufacturing automation. While these areas of research and development are newly advancing, specific use needed by the Government is not available. One particular technique that may be applicable is Deep Convolutional Generative Adversarial Networks (DC GANs) but other synthetic techniques are viable. The solution should provide data as seen at a nose-on view, top-down aerial view, and broad side view (i.e., plan, profile, and various oblique angles). The solution should demonstrate realism of the dataset through analysis and modeling. The solution will contain a synthetic dataset of frame-by-frame UAS images (not video sequences) in both visible and thermal bands that is useful for application to the training, validation, and testing of ML and artificially intelligent sub-systems for Naval Gunnery Systems. The solution should produce a dataset that conforms to commonly available public standards and contains images and labels of ground truth objects in accordance with class ontology, such as the Jet Propulsion Laboratory Semantic Web for Earth and Environmental Terminology (SWEET). The dataset should contain at least 3 types of group 1 UAS and at least 2 types of group 2 UAS. These UAS used to create datasets may be commercial products. The synthetically generated data shall be photo-realistic for both the visible and thermal imagery with high definition (HD) resolution. The labels should be at minimum rectangular labels, with segmentation labels being the objective. The dataset should also have diverse object and scene composition with variations in object size, orientation, background, lighting, and atmospheric conditions. The perspective and size of observation should also vary ranging between 2 pixels in the smallest dimension up to the full size of the image frames. The dataset should also be appropriately partitioned by the band of synthetic imagery (visible and thermal). It should also follow image dataset convention in the split of training for the training of ML systems; validation for the initial testing of the algorithm performance; and test for model performance verification with distinct data from the other sets. Each band of data will contain these three sub-sets. PHASE I: Develop a concept for automated synthetic generation dataset. Demonstrate its technical feasibility using analytical models, simulations, and testing. Modeling should demonstrate several produced image datasets in both the visible and thermal bands. The Phase I Option, if exercised, will include the initial design specifications and capabilities description to build a prototype solution in Phase II. PHASE II: Develop and deliver a prototype automated synthetic generation dataset as described in the Description and based on the results of Phase I. Demonstrate that the prototype meets the parameters of the Description through initial laboratory testing to confirm the design, functionality, and modelling underlying the theory of automated synthetic generation to evaluate and assess the sufficiency of the synthetic dataset. The prototype dataset will be provided to the Government for testing in a digital format using common file formats. PHASE III DUAL USE APPLICATIONS: Support the Navy in transitioning the automated synthetic generation technology to Navy use through testing and further development to facilitate the adaptation of the technology to Navy use in Naval Gunnery applications. The prototype will provide the foundation upon which to train, validate, and test UAS detection systems. The product itself may have limited applications in the commercial sector. However, the tools and process developed to create this dataset will be extremely valuable for the creation of additional datasets for commercial applications. These include autonomous vehicle automation, security systems, and manufacturing automation. REFERENCES: 1. Strickland, Eliza. Are You Still Using Real Data to Train Your AI?
