  • Patent number: 12446842
    Abstract: A method for processing breast tissue image data includes processing the image data to generate a set of image slices collectively depicting the patient's breast; for each image slice, applying one or more filters associated with a plurality of multi-level feature modules, each configured to represent and recognize an assigned characteristic or feature of a high-dimensional object; generating at each multi-level feature module a feature map depicting regions of the image slice having the assigned feature; combining the feature maps generated from the plurality of multi-level feature modules into a combined image object map indicating a probability that the high-dimensional object is present at a particular location of the image slice; and creating a 2D synthesized image identifying one or more high-dimensional objects based at least in part on object maps generated for a plurality of image slices.

  • Publication number: 20250299344
    Abstract: A road longitudinal slope estimation method based on unmanned aerial vehicle aerial photography video includes: collecting and correcting the traffic flow video of the road; taking the center line of the road as the reference line, extracting pixels on the reference line, and outputting the pixel gray space-time image on the reference line; performing the contour extraction of pixel gray space-time image; through the trajectory contour information, obtaining the complete trajectory data set; identifying the vehicle speed change point by using the energy distribution of wavelet transform; constructing the data set of road slope estimation, and based on the assumption of the actual length distribution of road pixels and the value of road longitudinal slope, applying a Bayesian network and a machine learning algorithm to iteratively obtain an expected value and variance of the actual length of the road pixel point and an estimated value of the road longitudinal slope.

  • Publication number: 20250140219
    Abstract: The invention includes a method including the steps of obtaining a plurality of images, each of the images in the plurality having at least one corresponding region, generating a merged image, the merged image also having the corresponding region. The step of generating includes selecting an image source from the plurality of images to source image data for the corresponding region in the merged image by comparing attributes of the corresponding regions of the plurality of images to identify the image source having preferred attributes.

  • Publication number: 20250082292
    Abstract: A method for processing breast tissue image data includes obtaining image data of a patient's breast tissue, processing the image data to generate a set of image slices, the image slices collectively depicting the patient's breast tissue; feeding image slices of the set through each of a plurality of object-recognizing modules, each of the object-recognizing modules being configured to recognize a respective type of object that may be present in the image slices; combining objects recognized by the respective object-recognizing modules to generate a synthesized image of the patient's breast tissue; and displaying the synthesized image.
