Abstract: An apparatus for image contrast enhancement and a method, electronic equipment that includes: a dividing unit configured to divide an input image into at least two layers; and detail degrees of the at least two layers are different; an enhancing unit configured to perform contrast enhancement on each of the at least two layers respectively; and degrees of enhancing contrasts of the layers are different; and a combining unit configured to combine the contrast-enhanced at least two layers. By dividing the input image into at least two layers with different detail degrees and performing contrast enhancement on the at least two layers at different degrees, the contrast of the image may be accurately and effectively enhanced, thereby a display effect of the image may be improved.
Abstract: A method includes obtaining at least one of projection data from a spectral scan or image data generated from the projection data, selecting a local reference dataset from the at least one of the projection data or the image data, determining a noise pattern for the selected reference dataset, estimating underlying local structure from the reference dataset based on the noise pattern, and restoring at least one of the projection data or the image data based on the estimated underlying local structure.
Abstract: A display apparatus which is also able to receive and identify fingerprints comprises a first substrate, a second substrate, a liquid crystal layer, a plurality of dummy pixel units located in a non-display region, a fingerprint identification module, and a plurality of data extending lines. Each of the dummy units comprises first and second auxiliary electrodes. The fingerprint identification module comprises signal transmitting layer and signal receiving components on the signal transmitting layer. The signal receiving component receives reflected ultrasonic wave and converts the received waves into fingerprint signal. The data extending line is electrically connected with the dummy pixel unit. The signal receiving component transmits the fingerprint signals to the at least one first auxiliary electrode and the data extending line thus receives the fingerprint signal.

Abstract: A method for identifying features in an image, the method comprising: a) from a first location, scanning the image along a scan path in a scan direction away from the first location so as to detect a border in the image at a second location; b) mapping a path defined by the border in a first direction along the border from the second location, the path being mapped in dependence on a border quality measure; c) determining whether the mapped path forms a perimeter; and d) if the mapped path does form a perimeter, scanning the image from the mapped path so as to detect a further border in the image; or if the mapped path does not form a perimeter, mapping a path defined by the border from the second location in a second direction along the border that is different to the first direction.
Abstract: A method for identifying a color block area in an image, the method comprising: a) scanning for border crossings in the image in a direction from a user-provided origin point; b) on finding a border crossing, tracing a path of the border such that the color block area is on a predetermined side of the traced path; and c) if the path encloses the origin point and is traced clockwise or counterclockwise according to the predetermined choice of keeping the color block area to the right or left respectively, determining that the border is the perimeter for the color block area; or if not, continuing to scan for border crossings in said direction.
Abstract: Methods and systems of identification of objects in query images are disclosed. Keypoints in the query images are identified corresponding to objects to be identified. Visual words are identified in a dictionary of visual words for the identified keypoints. A set of hits is identified corresponding to reference images comprising the identified keypoints. Reference images corresponding to the identified set of hits are ranked using clustering of matches in a limited pose space. The limited pose space comprises a one-dimensional table corresponding to the rotation between the object to be identified with respect to the reference image. A first subset of M reference images that obtained a rank above a predetermined threshold is then selected. Offline, hybrid and combined offline and hybrid systems for performing the proposed methods are disclosed.

Abstract: The present application discloses a method and an apparatus for processing point cloud data. The method in an embodiment comprises: presenting a to-be-labeled point cloud frame and a camera image formed by photographing an identical scene at an identical moment as the point cloud frame; determining, in response to an operation of selecting an object in the point cloud frame by a user, an area encompassing the selected object in the point cloud frame; projecting the area from the point cloud frame to the camera image, to obtain a projected area in the camera image; and adding a mark in the projected area, for labeling, by the user, the selected object in the point cloud frame according to the mark indicating an object in the camera image. This implementation can assist labeling personnel in rapidly and correctly labeling an object in a point cloud frame.

Abstract: Methods and systems for an image construction component capable of generating pixel information for certain regions of an image based on other, existing regions of the image. For example, the image construction component may identify a target block of pixels for which to generate pixel information and then use pixel information for pixels surrounding the target block of pixels in order to identify similar image information within pixels in another part of the image. These identified pixels may then be used in defining the pixel information of the target block of pixels and also used in blending the target block of pixels with the defined pixels surrounding the target block of pixels.
Abstract: An augmented reality system comprises one or more databases storing a passable world model data comprising a set of points pertaining to real objects of the physical world, and one or more object recognizers configured for running on the passable world model data. Each of the object recognizer(s) is programmed to recognize a predetermined object of the real world based on a known geometry of a corresponding set of points. The augmented reality system further comprises a head-worn augmented reality display system configured for displaying virtual content to a user based at least in part on the recognized object.
