摘要： A computer includes a processor and a memory, and the memory stores instructions executable by the processor to generate an observed overhead feature map from an overhead image of a geographic area; generate a ground-view feature map from a ground-view image captured by a camera within the geographic area, the camera oriented at least partially horizontally while capturing the ground-view image; project the ground-view feature map to an overhead view based on a geometric relationship, resulting in a projected overhead feature map; determine a rotation of the camera relative to the overhead image based on the projected overhead feature map and the observed overhead feature map; and determine a translation of the camera relative to the overhead image based on the projected overhead feature map and the observed overhead feature map.

摘要： The present disclosure provides a method (500) comprising receiving (510) images (e.g., 125A to 125G) of an object (110), the images (e.g., 125A to 125G) comprising first and second images. The method (500) then determines (530) feature points (810, 820) of the object (110) using the first images and determines (530, 540, 550) a three-dimensional reconstruction of a scene having the object (110). The method (500) then proceeds with aligning (560) the three-dimensional reconstruction with a three-dimensional mesh model of the object (110). The alignment can then be used to map (570) pixel values of pixels of the second images onto the three-dimensional mesh model. The directional radiosity of each mesh element of the three-dimensional mesh model can then be determined (580) and the hemispherical radiosity of the object (110) is determined (590) based on the determined directional radiosity.

摘要： A method and system for determining a location of artefacts and/or inclusions in a gemstone, mineral or sample thereof, the method comprising the steps of: surface mapping a gemstone, mineral or sample thereof to determine surface geometry associated with at least a portion of a surface of the gemstone, mineral or sample thereof; sub-surface mapping the gemstone, mineral or sample thereof using an optical beam that is directed at the surface along an optical beam path, wherein the optical beam is generated by an optical source using an optical tomography process; determining a surface normal at the surface at an intersection point between the optical beam path and the determined surface geometry; determining relative positioning between the surface normal and the optical beam path; and determining the location of artefacts and/or inclusions in the gemstone, mineral or sample thereof based on the sub-surface mapping step and the determined relative positioning.

摘要： A method for assessing the function of at least one sensory field of a subject, and apparatus and systems for carrying out the method, the method comprising: using a display, presenting stimuli to selected locations of the sensory field, the selected locations being centered at points on a sampling grid spanning a portion of the sensory field, wherein the individual stimuli if presented simultaneously at the sampling grid points would overlap in the space defined by the sensory dimensions of the field; using a sensor, detecting responses in the subject's sensory field evoked by the stimuli; and processing the detected responses to relate them to the function of the subject's sensory field at the selected locations.

摘要： The present invention provides a method for modulating or inhibiting modulation of the root architecture of a plant employing a new class of root architecture regulator (RAR) peptides, nucleotides encoding same, receptors therefor, binding agents thereof or agonists or antagonists thereof. Such methods encompass methods for increasing nutrient uptake by plants, increasing root nodule formation, promoting lateral root growth and development of plants, as well as methods for inhibiting root architecture modification resulting from root knot nematode action on plant roots. Also provided are RAR peptides, polynucleotides encoding RAR peptides and vectors and host cells comprising same, and plants obtained by methods of the invention or comprising RAR-encoding trans genes.

摘要： An optical parametric generator comprises a seed laser feeding an optical system. The seed laser is arranged to provide a seed beam at either a signal frequency of a signal wave or an idler frequency of an idler wave. Further, the optical parametric generator comprises a pump laser of a defined type feeding the optical system. The pump laser emits ultra-short optical pulses as a pump wave. In addition, the optical parametric generator comprises a second order non-linear crystal of a defined type arranged in the optical system. The defined type of the crystal and the defined type of the pump laser are selected so that the signal wave or the idler wave are locked in an edge of the pump wave.
