Abstract: Connected computing enables the use of highly diverse environments that support operating frameworks for contemporary civilization. But computing productivity and trustworthiness are undermined by such environments' largely inchoate organization. These environments and their identity infrastructures are fragmented, and unnecessarily unreliable, insecure, and insufficiently informative due to current computing entity (e.g., resource) identification infrastructure design, which lacks root identification reliability. Such reliability is enabled herein by a fundamentally accurate and authenticity ensuring, near-existential or existential quality, biometrically and liveness based, portable identification and provenance infrastructure. Such an infrastructure provides ubiquitously available identification information that can be used universally for identification processes.

One or more locations of the plant or the group of plants in the grow facility at one or more dates and times may be identified based on the corresponding UPI feature set as the plant or the group of plants grow in the grow facility. The plant or the group of plants may be de-registered from being tracked based on the corresponding UPI feature set when the plant or the group of plants reaches an end of a growth cycle in the grow facility. Alternatively, visual identifier devices and/or regions of interest (ROIs) may be used with or without UPI feature sets for such tracking.

Abstract: A relocalizer model for an environment is trained using an iterative process. To initialize the relocalizer model, an initial image is registered with its camera pose established as the reference. In each subsequent iteration of training, the relocalizer model is applied to additional images to predict pose estimates for the images. The images and their pose estimates are then leveraged in retraining of the relocalizer model. In general, the training of the relocalizer model entails extracting scene coordinates for pixels of a training image. The scene coordinates are then projected into a projection based on the pose estimate of the training image. A loss is calculated between the projection and the training image. And parameters of the relocalizer model are adjusted to minimize the loss. The iterative training may continue until an end condition is met. The trained relocalizer model is configured to input an image of the environment and to output the camera pose for the image.
