A device and a method that can be used to perform a correspondence analysis in image data in a particularly low-noise and efficient manner. The device and method include selecting image patches from individual images and generating a plurality of one-dimensional signals using even and odd convolution kernels in the spatial window in each case, and processing differences between the convolution results in a non-linear manner and accumulating these differences to form a correspondence function and evaluating this function.

Device and method for correspondence analysis in images

A device and process for determining sizes of particles of a particle stream. A first optical measuring system with a first dot matrix sensor and a lighting device, which transilluminates the measuring volume are provided. The first dot matrix sensor and the lighting device form a transmitted-light arrangement. The computing device determines projection areas of particles within the transilluminated measuring volume from the image data of the first dot matrix sensor. The optical measuring arrangement includes a second optical measuring system with a second dot matrix sensor for detecting the diffraction pattern of the particles. The computing device determines a size distribution of the particles in the measuring volume based on the projection areas and the diffraction pattern. The computing device forms the size distribution from particle sizes determined on the basis of the projection areas and from particle sizes determined on the basis of the diffraction pattern.

The invention relates to an image processing apparatus by means of which an image identification can take place in real time and which, with only very little or even no a priori information, is capable of carrying out a pertinent and reliable identification of objects. To this end, the connection probabilities are determined between two contour points in each case, taking into account the distance between the points, by means of a computation mechanism. Further provided is at least one classifier, which takes sets of calculated connection probabilities and selects from them subsets with at least three connection probabilities for possible links between at least three adjacent contour points, one of which is a previously determined central contour point, and, for each subset, sorts out that contour point which is adjacent to the central contour point and which has a possible link with the lowest connection probability to an adjacent contour point, provided that the link does not connect two points that are adjacent to the central point, and subsequently enters the contour points that have not been sorted out in a contour point list with connectors that identify the remaining links to the central point.

Method and apparatus for image processing

A digital image-processing device with a Bayer sensor and an image memory is provided in which the image data of the sensor is written into an image memory, and from this image memory, image data in the Bayer format with a length L and a width B is written continuously into a data buffer, and in which the sample values are combined by means of a computational device with the help of adders, in each case symmetrically to a central point of one or more (2n+1)&#xd7;(2n+1) neighborhoods, and one or more (n+1)&#xd7;(n+1) matrices are derived by means of the computational device, and from this (n+1)&#xd7;(n+1) matrix or these matrices, with the help of additional adders, at least one n&#xd7;n matrix is formed, and a first color component is in each case calculated from this by means of an adder network.

The invention relates to an image processing system for omnidirectional reading of optical patterns, for example of one-dimensional and two-dimensional codes. One object is to provide an image processing system which ensures high resolution with rapid processing at the same time in order, in particular, to allow processing in video real time and to provide reliable identification of the image information, in particular reliable and low-error edge detection, segmentation and object association. According to the invention, this is achieved by the use of a plurality of convolvers, which operate in parallel and/or using the time-division multiplexing method, for convolution of the digital image data, of a neighborhood processor () for reading and linking contour points (), and/or of a statistical processor for reading a segment list.

The methods and apparatuses determine contour points from image data and carried out a segmentation process on the basis of the contour points, during which associated contour points are combined to form objects for further processing.

In order to reduce a two-dimensional data structure to a minimum number of bits, a two-dimensional surface pattern is provided, which can be used in particular for identifying an absolute position on the surface and which has a pattern which comprises a SYNC pattern, which is used for synchronization, and a position-dependent code PC(x, y), with the SYNC pattern being variable and being formed in accordance with an already known formation rule.

A sensor unit ( ), a device, and a process for inspection of a surface ( &Dgr;) of an object ( ) for the purpose of identifying surface characteristics, such as structural defects. The device contains an emitting module ( ) and a receiving module ( ). The emitting module emits at least one beam bundle ( &Prime;). The receiving module has at least one light receiver ( ). A rotating polygonal mirror wheel ( ) is located in the focal point of a parabolic mirror ( ). A beam bundle ( ) of the laser ( ) is directed onto the mirror ( ) by means of a telecentric lens, which guides the emitter and receiver beam on the same optical axis, whereby the parabolic mirror ( ) guides the deflected beam bundle ( &Prime;) under a constant angle relative to the axis of symmetry ( ) of the parabolic mirror ( ) along a scanning line ( ) over the object ( ). The diffusely reflected beam bundle, after being deflected out of the common beam path, impinges on the processing unit ( ).
