Abstract: Using a pre-trained and fixed Vision Transformer (ViT) model as an external semantic prior, a generator is trained given only a single structure/appearance image pair as input. Given two input images, a source structure image and a target appearance image, a new image is generated by the generator in which the structure of the source image is preserved, while the visual appearance of the target image is transferred in a semantically aware manner, so that objects in the structure image are “painted” with the visual appearance of semantically related objects in the appearance image. A self-supervised, pre-trained ViT model, such as a DINO-VIT model, is leveraged as an external semantic prior, allowing for training of the generator only on a single input image pair, without any additional information (e.g., segmentation/correspondences), and without adversarial training. The method may generate high quality results in high resolution (e.g., HD).

Abstract: The present disclosure provides a search navigation system and method for an online store. The search navigation method includes obtaining attribute tags associated with available inventory associated with the online store, and detecting a buyer event associated with the online store. In response to the buyer event, a search navigation graph is generated for the online store based on a search navigation template graph. The search navigation graph comprises a hierarchical graph where each node in the search navigation graph represents a respective attribute tag, and the search navigation graph includes only nodes of the search navigation template graph representing attribute tags associated with the available inventory associated with the online store. A search navigation bar with selectable icons is displayed in a user interface. The selectable icons are a representation of a respective attribute tag represented by a respective node of the search navigation graph.

Abstract: A system, a computerized apparatus and a method for drowning detection based on swimmer analytics. The method comprises obtaining a visual input cameras observing a water area and analyzing each swimmer in the water area based on the visual input. Said analyzing comprises determining a risk level of each swimmer, whereby a first risk level is determined for a first swimmer and a second risk level is determined for a second swimmer, wherein the first risk level is higher than the second risk level; and automatically detecting potential drowning events for each swimmer. Said automatically detecting is performed by utilizing computational resources in a non-uniform manner. Said automatically detecting comprises applying increased computational resources with respect to the first swimmer, and applying reduced computational resources with respect to the second swimmer. The increased computational resources are higher than the reduced computational resources.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for using location aliases. In some implementations, a query is received, and a user that submitted the query is identified. It can be determined that one or more terms of the query represent an alias for a user-specific geographical location that has not been designated for the identified user. In response, a prompt can be provided to the user to specify a geographical location corresponding to the one or more query terms, data indicating a geographical location is received, and data is stored that indicates that, for the identified user, the one or more terms are an alias for the geographical location. One or more search results responsive to the query are provided, where the alias corresponds to the geographical location input in response to the prompt.

Abstract: A propulsion system for a vehicle comprises at least one propeller and at least one ducted fan. Each of the propellers is mounted on a respective duct of the ducted fan's outer perimeter and is adapted to be driven by a first electric motor. Each of the ducted fans is mounted within the duct and is adapted to be driven by a second electric motor. The rotation speeds and the blade pitch angles of the propellers and of the fans are controllable to achieve optimized efficiency of the propulsion unit, reduction of the noise of the system and minimization of combined torque of the system on the vehicle, by independently controlling the ducted fan RPM, the propeller RPM, and the propeller blades pitch angle.
