A vehicular trailer hitching assist system includes a rear backup camera disposed at a rear portion of a vehicle and a control disposed in the vehicle. A display device includes a video display screen operable to display video images for viewing by a driver of the vehicle. During a hitching maneuver event undertaken by the driver to hitch a trailer hitch of the vehicle to a trailer tongue of a trailer, and while the driver of the vehicle is maneuvering the vehicle to hitch the vehicle to the trailer, the control outputs video images derived from image data captured by the rear backup camera for display by the video display screen. At least one overlay overlays the displayed video images to guide the driver during the hitching maneuver. The at least one overlay aids in guiding connection of the trailer hitch of the vehicle to the trailer tongue of the trailer.

The present invention relates to a method for analysing a set of food particles, comprising the steps of acquiring a digital colour image of a plurality of particles arranged on a substrate, detecting portions of the image corresponding to each particle, determining the colour of each portion of the determined image, and measuring a distance between the determined colour of one portion of the image and a predetermined colour of a predetermined particle type.

A tire-enhancement product has a container comprising a dissolvable packaging material; and a solute encased in the container that is inert to the solute. The container is configured to be placed in an interior volume of a tire, to which solvent can be added. The container is configured to dissolve when placed in a predetermined solvent, and the solute is configured to mix with the solvent to form a tire-enhancement mixture.

A (decoded) picture may be split into subpictures/tiles. Information on the subpictures may be obtained by a decoding device, and a decoding procedure may be performed on the basis of the information on the subpictures. In addition, information on the tiles may be obtained by a decoding device, and a decoding procedure may be performed on the basis of the information on the tiles. According to embodiments of the present document, subpicture-related information and tile-related information can be efficiently signaled, and an in-loop filtering procedure can be performed on the basis of the subpicture-related information.

A tree crown extraction method based on UAV multi-source remote sensing includes: obtaining a visible light image and LIDAR point clouds, taking a digital orthophoto map (DOM) and the LIDAR point clouds as data sources, using a method of watershed segmentation and object-oriented multi-scale segmentation to extract single tree crown information under different canopy densities. The object-oriented multi-scale segmentation method is used to extract crown and non-crown areas, and a tree crown distribution range is extracted with the crown area as a mask; a preliminary segmentation result of single tree crown is obtained by the watershed segmentation method based on a canopy height model; a brightness value of DOM is taken as a feature, the crown area of the DOM is performed secondary segmentation based on a crown boundary to obtain an optimized single tree crown boundary information, which greatly increases the accuracy of remote sensing tree crown extraction.
