Publication number: 20240138672Abstract: The invention provides an imaging system (102) for imaging a fundus (104) of an eye (106), which has an optical axis (116). The imaging system (102) has a light source (108), an illumination path (118) along which light travels from the light source (108) to the eye (106), a light sensor (10) and imaging optics (44) defining an imaging axis (114), and at least one objective lens (112) aligned with the optical axis (116). At least a part of the illumination path (118) is substantially coaxial with the imaging axis (114), and the optical axis (116) is tilted with respect to the imaging axis (114).Type: ApplicationFiled: June 14, 2022Publication date: May 2, 2024Inventors: Hans Einar Overjordet, Anders Eikenes, Jukka Alasirnioe

Patent number: 11205087Abstract: Systems and methods are provided for capturing time-stamped data from whiteboard video signals and producing high-resolution whiteboard images. Local patches around a multitude of pixels in the whiteboard are used in classifying background white pixels and foreground color pixels for each foreground marker color. Clustering is performed in alternative color spaces globally and locally in defining background white and each foreground marker color. Color normalization is performed for each foreground pixel classified as a foreground marker color and for each image sensor color plane separately utilizing the maximum local background white and the darkest pixel intensities in local patches. Strokes are reconstructed based on spline interpolation of inflection points of cross sections along the length of each stroke for a foreground marker color with a predetermined width.Type: GrantFiled: June 30, 2019Date of Patent: December 21, 2021Assignee: HUDDLY ASInventors: Anders Eikenes, Stein Ove Eriksen, Jan Tore Korneliussen, Eamonn Shaw

Patent number: 10511766Abstract: Systems and methods are provided for alleviating bandwidth limitations of video transmission and enhancing the quality of videos at a receiver. In particular, an improved video transmission system is provided for generating high-resolution videos. The systems have therein a transmitter and a receiver; the transmitter includes an outer encoder and a core encoder, while the receiver includes a core decoder and an outer decoder. The outer encoder is adapted to receive the video from a source and separately output a salient video and an encoded background, and the outer decoder is adapted to merge the background with the salient video thereby producing an enhanced video. Also provided is a system that simulates pan-tilt-zoom (PTZ) operations without PTZ hardware. Further provided are methods for video transmission whereby a background model is initialized, a background independently encoded, updated incrementally, and the background and the updates transmitted independently from the video.Type: GrantFiled: July 31, 2017Date of Patent: December 17, 2019Assignee: HUDDLY ASInventors: Jan Tore Korneliussen, Anders Eikenes, Håvard Pedersen Alstad, Stein Ove Eriksen, Eamonn Shaw

Patent number: 10237548Abstract: Systems and methods are provided for alleviating bandwidth limitations of video transmission, enhancing the quality of videos at a receiver, and improving the VR/AR experience. In particular, an improved video transmission and rendering system is provided for generating high-resolution videos. The systems have therein a transmitter and a VR/AR receiver; the transmitter includes an outer encoder and a core encoder, while the receiver includes a core decoder and an outer decoder. The outer encoder is adapted to receive the video from a source and separately output a salient video and an encoded three-dimensional background, and the outer decoder is adapted to merge the background with the salient video thereby producing an augmented video.

Patent number: 7633614Abstract: A device and a method for detection of characteristic features of a medium that is wholly or partly transparent, wherein said medium is placeable in an observation area in a light path extending between a light source and a light detector, wherein said medium is illuminated by the light source in the observation area, wherein at least one light-directing optical element is arranged in connection with the observation area. Light transmitted through said medium, which is deflected by said medium when it is in said area and thus causes a change of light direction in said area, is detected. Characteristics of said medium are determined by spectrometry of the received light-deflected light, and a wavelength-sensitive element is used at a position in the light path, either at or as a part of the light source or the light detector.Type: GrantFiled: September 23, 2005Date of Patent: December 15, 2009Assignee: Tomra Systems ASAInventors: Karl Henrik Haugholt, Svein T.
