Abstract: In a method and apparatus for evaluating image segments for a correspondence calculation, an image signal is received from an image sensor and is evaluated in order to determine the extent to which, for a selected region of the image sensor, noise caused by the image sensor is present; and a resultant evaluation parameter, for an image segment of an image acquired by the image sensor, which describes whether the image segment is suitable for a correspondence calculation, is ascertained. The image segment corresponding to the selected region of the image sensor and the resultant evaluation parameter are ascertained based on the determined extent of the noise.

Abstract: An electronic device comprises circuitry implementing a depth map enhancer. The depth map enhancer obtains an initial depth map corresponding to a scene and an image of the scene. The depth map enhancer generates a refined depth map corresponding to the scene using an optimizer, the initial depth map and the image. The refined depth map includes estimated depth indicators corresponding to at least a first depth-information region, identified based at least in part on a first criterion, of the initial depth map. Input based on the refined depth map is provided to an image processing application.

Abstract: A method for ascertaining/mapping between a matrix element (ME) and a comparison ME (CME) of a comparison matrix (CM), including writing the ME position in a table element (TE) of a correspondence table (CT) for a number of MEs, and following a predefined offset, reading out a TE, ascertaining the ME position stored in the TE until the read for the same number of MEs has been performed, establishing a mapping from the TE's read-out position and a CME's current position. The writing includes reading out a ME feature, ascertaining an access feature (AF) from the ME feature, ascertaining a TE of the CT from the AF, and writing the ME position in the ascertained TE. The reading includes reading out a CME feature, ascertaining an AF from the CME, ascertaining a TE of the CT from the AF, and reading out the ME's stored position from the ascertained TE.

Abstract: A method in a training phase includes acquiring a first image of an environment of a means of locomotion from a first position, using an optical sensor; acquiring a second image of the environment of the means of locomotion from a second position, differing from the first position, using the optical sensor; ascertaining features that represent the first image and ascertaining features that represent the second image using an algorithm for feature extraction; selecting those features of the first and the second image which do not meet a predefined rating criterion; and ascertaining significant similarities between the selected features of the first and the second image and storing references that represent the significant similarities. A method is performed in an execution phase that makes use of the stored features of the training phase.

Abstract: A method for processing image data. The method includes a step of determining correspondence data as the result of a correspondence generation between first image data that represent data recorded by a camera at a first point in time, and preceding image data that represent data recorded by the camera at a preceding point in time. In a step of determining, depth data are determined on the basis of an ego-motion estimate carried out using the correspondence data. In a step of ascertaining, fusion data are ascertained using the depth data and the transferred fusion data, the fusion data including an item of depth information based on the image data.

Abstract: A method for determining an ego-motion of a vehicle is described, which is carried out in driver assistance systems, particularly in parking assistance systems. The method involves: taking a sequence of images, successive in time of a vehicle surroundings by a vehicle camera; determining, based on the image sequence, at least one motion flow with regard to an object in the vehicle surroundings; and determining the ego-motion of the vehicle based on the at least one motion flow.

Abstract: A method for recognizing directional structures on a window pane of a vehicle is described. The method includes carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane. The method further includes recognizing a directional structure based on the assessment.
