    Abstract: An ultrasound scanning technique for biological tissue examines the radio frequency signals derived from reflected ultrasonic energy to identify signal parameters indicative of particular tissue histology. Such identification is then used to produce a histological image of the biological tissue. The technique is particularly useful in the examination of blood vessels to identify different types of plaque within the vessel wall. Lipid plaques produce relatively low levels of reflection. Calcified plaques produce high levels of regular reflection. Fibrous plaques may be identified as a highly homogeneous thickened wall area that does not show the characteristics of a lipid plaque. A homogeneity value for the radio frequency signal is calculated for all areas not identified as lipid plaques or calcified plaques and then this homogeneity value is mapped to a colour that is displayed within the histological image.

    Abstract translation: 用于生物组织的超声扫描技术检查从反射的超声波能量得到的射频信号，以识别指示特定组织组织学的信号参数。 然后使用这种鉴定来产生生物组织的组织学图像。 该技术在血管检查中特别有用，以鉴别血管壁内不同类型的斑块。 脂质斑块产生相对较低的反射水平。 钙化斑块产生高水平的定期反射。 纤维斑可以被鉴定为不显示脂质斑块特征的高度均匀的增稠壁面积。 对于未识别为脂质斑块或钙化斑块的所有区域计算射频信号的均匀性值，然后将该均匀性值映射到在组织学图像内显示的颜色。

    Abstract: Certain examples described herein enable semantically-labelled representations of a three-dimensional (3D) space to be generated from video data. In described examples, a 3D representation is a surface element or ‘surfel’ representation, where the geometry of the space is modelled using a plurality of surfaces that are defined within a 3D co-ordinate system. Object-label probability values for spatial elements of frames of video data may be determined using a two-dimensional image classifier. Surface elements that correspond to the spatial elements are identified based on a projection of the surface element representation using an estimated pose for a frame. Object-label probability values for the surface elements are then updated based on the object-label probability values for corresponding spatial elements. This results in a semantically-labelled 3D surface element representation of objects present in the video data. This data enables computer vision and/or robotic applications to make better use of the 3D representation.

    Abstract: Certain examples described herein relate to mapping a space using a multi-directional camera. This mapping may be performed in relation to a robotic device comprising a monocular multi-directional camera device and at least one movement actuator. The mapping may generate an occupancy map to determine navigable portions of the space. In examples, a movement of the robotic device around a point in a plane of movement is instructed using the at least one movement actuator. Using the monocular multi- directional camera device, a sequence of images are then obtained (610) at a plurality of different angular positions during the instructed movement. Pose data is determined (620) from the sequence of images. The pose data is determined using a set of features detected within the sequence of images. Depth values are then estimated (630) by evaluating a volumetric function of the sequence of images and the pose data. The depth values are processed (640) to populate the occupancy map for the space.
