Abstract: A camera of a mobile device includes at least two entrance openings and at least two image sensors. A first entrance opening is assigned to a first image sensor via a first imaging path and a second entrance opening is assigned to a second image sensor via a second imaging path. Each of the entrance openings has a light entrance surface with a longitudinal direction and a transverse direction running perpendicular thereto. The length of the entrance opening in the longitudinal direction is at least 1.2 times larger than the width of the entrance opening in the transverse direction. The first imaging path and the second imaging path each include anamorphic optics. In addition, a mobile device including the camera, and a method for generating an image representation with the camera are provided.

Abstract: A System/Method/Device for segmenting the choroid-scleral layer from an optical coherent tomography (OCT) volume scan. The present system uses a deep learning machine model based on a neural network that include multiple convolution layers, but no deconvolution layers. Rather, the present neural network is based on a novel architecture based on the discrete cosine transform.

Abstract: An OCT system includes a machine learning (ML) model trained to receive a single OCT scan/image and provide an image translation and/or denoise function. The ML model may be based on a neural network (NN) architecture including a series of encoding modules in a contracting path followed by a series of decoding modules in an expanding path leading to an output convolution module. An intermediate error module determines a deep error measure, e.g., between a training output image and at least one encoding module and/or decoding module, and an error from the output convolution module is combined with the deep error measure. The NN may be trained using true averaged images as ground truth, training outputs. Alternatively, the NN may be trained using randomly selected, individual OCT images/scans as training outputs.

Abstract: An ophthalmic imaging system provides an automatic focus mechanism based on the difference of consecutive scan lines. The system also provides of user selection of a focus point within a fundus image. A neural network automatically identifies the optic nerve head in an FA or ICGA image, which may be used to determine fixation angle. The system also provides additional scan tables for multiple imaging modalities to accommodate photophobia patients and multi-spectrum imaging options.

Abstract: A method and a device for measuring the topography and/or the gradients and/or the curvature of an optically active surface of an object are disclosed. The device allows the object to be arranged in a receiving region with a contact surface for contact with the object. Inside the device, there is a plurality of point light sources that provide light that is reflected at the surface to be measured of an object arranged in the receiving region. The device includes at least one camera with an objective assembly and an image sensor for detecting a brightness distribution which is produced on a light sensor by the light of the point light sources reflected at the surface to be measured.

Abstract: A method to detect a defect on a lithographic sample includes the following steps: detection light and a detector having at least one sensor pixel are provided. Further, a detection pattern is provided causing a light structure of the detection light being structured at least along one dimension (1D, x). The detection pattern is aligned such that the detector is aligned normal to an extension (xy) of the light structure. Further, a complimentary pattern is provided having a 1D structure which is complimentary to that of the detection pattern. The sample is moved relative to the detection pattern while gathering the detection light on the detector. Further, a reference sample without defects or with negligible defects is provided. The reference sample also is moved relative to the detection pattern while gathering the detection light on the detector. A defect (S1 to S4) localization on the sample is decoded by correlation using the complementary pattern.

Abstract: Improvements in image quality can be obtained by leveraging non-linear neural-network based feature recovery across multiple imaging modalities. Input imaging data is acquired, including first imaging data and second imaging data acquired using different imaging modalities. The first imaging data can have lower image quality and a larger FOV than the second imaging data. The first and second imaging data can be aligned and the aligned regions can be used to train a neural network to minimize the difference between the second imaging data and output data processed from the overlapping portion of the first imaging data. Once trained, the neural network can be used to generate improved image quality output from all of the first imaging data.

Abstract: Improved (e.g., high-throughput, low-noise, and/or low-artifact) X-ray Microscopy images are achieved using a deep neural network trained via an accessible workflow. The workflow involves selection of a desired improvement factor (x), which is used to automatically partition supplied data into two or more subsets for neural network training. The neural network is trained by generating reconstructed volumes for each of the subsets. The neural network can be trained to take projection images or reconstructed volumes as input and output improved projection images or improved reconstructed volumes as output, respectively. Once trained, the neural network can be applied to the training data and/or subsequent data—optionally collected at a higher throughput—to ultimately achieve improved de-noising and/or other artifact reduction in the reconstructed volume.

Abstract: The generation of a 3D reconstruction of an object is disclosed, which includes illuminating the object, capturing image data in relation to the object, and calculating the 3D reconstruction of the object from the image data. The image data contains first image data and second image data, wherein the first image data are captured when the object is illuminated with illumination light, at least some of which, in relation to an object imaging beam path, is reflected light which illuminates the object, wherein the second image data are captured from different recording directions when the object is illuminated with illumination light, at least some of which is guided in the object imaging beam path, and wherein the 3D reconstruction of the object is calculated from the first image data and the second image data.

Abstract: Stereoscopy in which at least one image of a scene is recorded from a first viewing angle, and at least one image of the scene is recorded from a second viewing angle. The scene is recorded multiple times from the first viewing angle. A first combination image is obtained from the various images recorded from the first viewing angle, said combination image according to the stipulation of a comparison algorithm having smaller differences in relation to at least one image also recorded from the second viewing angle or smaller differences in relation to a second combination image obtained from the images from the second viewing angle than each individual image recorded from the first viewing angle. An image of the scene with the depth information is obtained from the first combination image and at least one image from the second viewing angle or the second combination image.

Abstract: A method for operating a mobile terminal including an image recording device includes capturing at least one recording of a scene and checking at least one of optionally several recordings checked for the presence of a light source. Subsequently, a position of the light source is determined relative to an optical center and a shape, an intensity and/or a color is determined for the light source. An algorithm trained in relation to imaging properties of a given optical unit is then used to generate a flare image of a lens flare for this light source and the given optical unit using the position of the light source. The flare image is subsequently combined with the recording to form a combination image and the combination image is stored in a memory component.
