  • Patent number: 11501444
    Abstract: The present invention relates to a method for color visualization and separation of a natural and medical image comprising pixels defined by color pixel vector a=[a1a2, a3] in a Cartesian color space (e.g. RGB), where the color pixel vector is represented by a pure quaternion q=+a1i+a2j+a3k with i,j, k satisfying: i2=j2=k2=ijk=?1, ij=?ji=k,jk=?kj=i, ki=?ik=j and the image is decomposed into q+ and q using the orthogonal 2D planes split concept according to: (formula (I)) wherein/and g are pure unit quaternions or f and g describe interactively determined or computed colors (s1, s2). The method allows not only visualizing and separating certain colors in a digital image in a rapid fashion, but also permits a flexible definition pertinent to the kind of colors that can be visualized or separated by defining the corresponding decompositions by means of pure unit quaternions/and g. Colors s1, s2 can be defined manually or computed automatically from the image.

  • Patent number: 11501483
    Abstract: An unmanned aerial vehicle (UAV) may couple to a sensor payload device that includes cameras, radar, lidar, and/or other sensors. The UAV, coupled to the sensor payload device, may fly within the airspace of and/or around a property and capture images and/or sensor measurements of the property. The images and sensor measurements may be certified so that they may be verified as unaltered by viewers. A 3D representation of the property may be generated, and defects in the property may be detected by comparing the 3D representation to media depicting property defects. A report identifying the defects may be generated.

  • Patent number: 11481956
    Abstract: A medical image processing apparatus according to embodiments includes processing circuitry. The processing circuitry acquires three-dimensional medical image data in which a structure of a subject is rendered. The processing circuitry sets an eye point and an eye direction in the three-dimensional medical image data, generates two-dimensional first medical image data from the three-dimensional medical image data, and generates two-dimensional second medical image data in which display manners differ between a first portion on the opposite side to the eye point side in the eye direction of the structure rendered in the two-dimensional first medical image data and a second portion on the eye point side of the structure rendered in the two-dimensional first medical image data. The processing circuitry displays a medical image represented by the second medical image data on a display.

  • Patent number: 11474660
    Abstract: Techniques for gradually transitioning a user to a second navigation scheme while using a first navigation scheme in a 3D design application that generates and displays a 3D virtual environment. The design application initially implements the first navigation scheme and a set of function tools of the standard navigation scheme. The design application monitors for a set of patterns of navigation actions during use of the first-person navigation scheme, each pattern being performed more efficiently when using the standard navigation scheme. Upon detecting a pattern using the first-person navigation scheme, the design application may switch to the standard navigation scheme. Also, upon detecting selection of a function tool, the design application may switch to the standard navigation scheme during use of the function tool. When the function tool is closed, the design application may switch back to the first-person navigation scheme.

  • Patent number: 11373368
    Abstract: Two-dimensional aerial images and other geo-spatial information are processed to produce land classification data, vector data and attribute data for buildings found within the images. This data is stored upon a server computer within shape files, and also stored are source code scripts describing how to reconstruct a type of building along with compiled versions of the scripts. A software game or simulator executes upon a client computer in which an avatar moves within a landscape. A classifier classifies a type of building in the shape file to execute the appropriate script. Depending upon its location, a scene composer downloads a shape file and a compiled script is executed in order to reconstruct any number of buildings in the vicinity of the avatar. The script produces a three-dimensional textured mesh which is then rendered upon a screen of the client computer to display a two-dimensional representation of the building.

  • Patent number: 11259874
    Abstract: A method of generating a custom three-dimensional model of a bone is disclosed. A 2D image of the bone is obtained and an orientation and scale of the 2D image are aligned to a pre-determined coordinate system. Based on the 2D image, a representative bone is identified from a library of representative bones that are aligned to the pre-determined coordinate system. Based on the 2D image, an ideal view of a 3D model of the representative bone is selected. Modifications may be made to the 3D model by using additional representative bones from the library. A custom three-dimensional model of the bone is thereby generated.

  • Patent number: 11244513
    Abstract: The technology disclosed relates to a method of realistic rendering of a real object as a virtual object in a virtual space using an offset in the position of the hand in a three-dimensional (3D) sensory space. An offset between expected positions of the eye(s) of a wearer of a head mounted device and a sensor attached to the head mounted device for sensing a position of at least one hand in a three-dimensional (3D) sensory space is determined. A position of the hand in the three-dimensional (3D) sensory space can be sensed using a sensor. The sensed position of the hand can be transformed by the offset into a re-rendered position of the hand as would appear to the wearer of the head mounted device if the wearer were looking at the actual hand. The re-rendered hand can be depicted to the wearer of the head mounted device.
