摘要： A method comprises, with a predetermined pattern, irradiating an area of a sample (1) with electromagnetic radiation (4). The method also comprises, by each of a plurality of cameras simultaneously, during the irradiating of the sample with the predetermined pattern, acquiring an image of the sample area in a wavelength range specific to that camera. The method also comprises irradiating the sample area with a calibration pattern detectable by each of the cameras. The method also comprises each of the cameras detecting the calibration pattern from its respective view of the sample area. The method also comprises, based on the detecting of the calibration pattern by each of the cameras, determining rules for transforming respective images acquired by the cameras from the respective views to a primary view. The method also comprises aligning the acquired images of the sample area by using the determined rules.

摘要： Systems and methods for iteratively computing an image registration or an image segmentation. The registration and segmentation computations are driven by an optimization function that includes a similarity measure component whose effect on the iterative computations is relatively mitigated based on a monitoring of volume changes o volume elements at image locations during the iterations. There is also a system and a related 5 method to quantify for a registration error. This includes applying a series of edge detectors to input images and combining related filter responses into a combined response. The series of filters are parameterized with a filter parameter. An extremal value of the combined response is then found and a filter parameter associated with said extremal value is then returned as output. This filter parameter relates to a registration error at a given image 10 location.

摘要： A method and a device for inspecting engravings in a tire mold capable of determining the suitability of engravings formed on a surface of an annular side plate, which is a component of the tire mold, in a reduced time and with high precision. The method comprises the steps of: inputting in advance into a data processing device (2) two-dimensional image master data (9) of an engraving (8) formed on a surface (7a) of a side plate (7) in a plan view using basic data set as a reference, the image master data (9) having a radial component (t) and a radial position (r) of the engraving (8) corrected on the basis of a locus length in a radial direction of the surface (7a) of the side plate (7); generating two-dimensional image actual measurement data, the image actual measurement data having a radial component and a radial position of three-dimensional data acquired via actual measurement corrected on the basis of a radial locus length of a surface (7a) of a side plate (7) on which actual measurement was performed; and determining whether or not an image shape and an image position of the image actual measurement data (10) is within a tolerable range via comparing image contours of the image master data (9) and the image actual measurement data (10) by the data processing device (2).

摘要： The present invention relates to an illustration of an annotation (22) at a sample slide (14). It is the intention for the invention to copy the annotation (22) provided at a reference slide (12) to the sample slide (14). Typically, a reference image (26) of the reference slide (12) is provided, in particular by scanning the reference slide (12). The reference image (26) therefore has the information about a reference slice (16) which is carried by the reference slide (12). Furthermore, the reference slide (12) has been marked with a region of interest (20) and the annotation (22), which can be associated with the region of interest (20). If such reference slide (12) is scanned, the respective reference image (26) comprises the information about the marked region of interest (20) as well as the annotation (22), too. Furthermore, the sample slide (14) carrying a sample slice (18) can be scanned, in order to provide a sample image (28). The sample slice (18) and the reference slice (16) are cut from the same object (10) of a biological material. In particular, the sample slice (16) has been cut directly after a cut of a material block has been preformed to provide the reference slice (18). Since the reference slice (16) and the sample slice (18) are from the same object (10), their features are very likely that the reference image (26) and the sample image (28) are very similar. Due to this similarity, the annotation (22) of the reference slide (12) is copied on a basis of an image recognition between reference image (26) and the sample image (28) to the sample slide (14).
