  • Patent number: 10789695
    Abstract: Systems, methods, and computer-readable media for feedback on and improving the accuracy of super-resolution imaging. In some embodiments, a low resolution image of a specimen can be obtained using a low resolution objective of a microscopy inspection system. A super-resolution image of at least a portion of the specimen can be generated from the low resolution image of the specimen using a super-resolution image simulation. Subsequently, an accuracy assessment of the super-resolution image can be identified based on one or more degrees of equivalence between the super-resolution image and one or more actually scanned high resolution images of at least a portion of one or more related specimens identified using a simulated image classifier. Based on the accuracy assessment of the super-resolution image, it can be determined whether to further process the super-resolution image. The super-resolution image can be further processed if it is determined to further process the super-resolution image.

  • Patent number: 10789679
    Abstract: A plurality of captured images is first acquired by capturing images of an object while changing a focal position along an optical axis. Then, variations in magnification among the captured images are acquired. On the basis of the variations in magnification, corresponding pixels in the captured images are specified, and definition is compared among the corresponding pixels. Then, an image reference value indicating the number of a captured image that is to be referenced as the luminance value of each coordinates in an omnifocal image is determined on the basis of the result of comparison of the definition. The omnifocal image is thereafter generated by referencing the luminance value in the captured image indicated by the image reference value for each coordinates. In this way, the omnifocal image that reflects the position and size of the object accurately can be generated.

  • Patent number: 10740983
    Abstract: Colored three-dimensional digital model generation techniques and systems are described. In one example, scanning techniques are employed by a scanning system that scans a physical object while disposed within packaging to form a three-dimension digital model. A model coloring system is employed to color the three-dimensional digital model. A two-dimensional digital image is employed that captures the same or similar physical object. In one example, features of the model are matched to the image. This is then used to align a viewing perspective with respect to the model with a viewing perspective of the object within the digital image, e.g., to find which “view” of the model corresponds with the image. The color is then applied from the digital image to the model, e.g., from pixels of the image to corresponding points in the model.

  • Patent number: 10679363
    Abstract: A reduced noise image can be formed from a set of images. One of the images of the set can be selected to be a reference image and other images of the set are transformed such that they are better aligned with the reference image. A measure of the alignment of each image with the reference image is determined. At least some of the transformed images can then be combined using weights which depend on the alignment of the transformed image with the reference image to thereby form the reduced noise image. By weighting the images according to their alignment with the reference image the effects of misalignment between the images in the combined image are reduced. Furthermore, motion correction may be applied to the reduced noise image.

A display unit displays the retrieved one or more second inspection results. One or more specific inspection results that correspond to the other of the image feature or the construction condition are retrieved from among the retrieved one or more second inspection results. The display unit displays the one or more specific inspection results preferentially over the other inspection results among the second inspection results.

  • Patent number: 10089712
    Abstract: Systems, methods, and other embodiments are disclosed for correcting errors in the geo-spatial locations of acquired image data. In one embodiment, acquired aerial or satellite image data is segmented to generate extracted boundary data. The extracted boundary data represents boundaries of features of a portion of the Earth's surface, but at incorrect geo-spatial coordinates. The extracted boundary data is matched to expected boundary data derived from ground truth data. The expected boundary data represents boundaries of the features at correct geo-spatial coordinates. Adjustment parameters are generated that represent a geo-spatial misalignment between the extracted boundary data and the expected boundary data. Metadata in a header of the acquired image data is modified to include the adjustment parameters. The adjustment parameters may be applied to the acquired image data to generate corrected image data at correct geo-spatial coordinates.

  • Patent number: 10088658
    Abstract: Referencing of image acquired in multiple rounds of imaging is disclosed. In certain implementations, a baseline round of images are acquired and registered to one another to establish a global transformation matrix. In a subsequent round of image acquisition, a limited number of field of view images are initially acquired and registered to the corresponding baseline images to solve for translation, rotation, and scale. The full set of baseline images is then acquired for the subsequent round and each image is pre-rotated and pre-scaled based on the transform determined for the subset of images. The pre-rotated, pre-scaled images are then registered using a translation-only transform.
