US10783406B1 Method for detecting structural surface cracks based on image features and bayesian data fusion
A method for detecting structural surface cracks based on image features, support vector machines and Bayesian data fusion, including: 1) acquisition of a video of a structural surface and establishment of an image library; 2) calculation of texture features of the image frames by local binary patterns; 3) scanning and grouping for image patches of cracks on the image frames using two-stage support vector machine; 4) Bayesian data fusion and decision. The video image detection acquires images of many areas where human beings are difficult to reach; computers are adopted to identify cracks on surfaces of the structural elements, which can greatly reduce the identification workload and labor cost, and increase the crack detection rate. The invention has a better adaptability to the light strength on the structural surface, thus providing better identification for cracks.
US10783403B2 Automated design testing through deep learning
A method is used in evaluating a test subject in computing environments. A first machine learning system generates test subject features. A second machine learning system analyzes the test subject to detect distinguishing features of the test subject. A third machine learning system performs natural language processing on the test subject features to create evaluation information associated with the test subject. A test subject evaluation system provides an evaluation of the test subject based on the distinguishing features and the evaluation information.

US10783394B2 Equivariant landmark transformation for landmark localization
A method, computer readable medium, and system are disclosed to generate coordinates of landmarks within images. The landmark locations may be identified on an image of a human face and used for emotion recognition, face identity verification, eye gaze tracking, pose estimation, etc. A transform is applied to input image data to produce transformed input image data. The transform is also applied to predicted coordinates for landmarks of the input image data to produce transformed predicted coordinates. A neural network model processes the transformed input image data to generate additional landmarks of the transformed input image data and additional predicted coordinates for each one of the additional landmarks. Parameters of the neural network model are updated to reduce differences between the transformed predicted coordinates and the additional predicted coordinates.

US10783378B2 Systems and methods for creating video summaries
Video information defining video content may be accessed. Highlight moments within the video content may be identified. Flexible video segments may be determined based on the highlight moments. Individual flexible video segments may include one or more of the highlight moments and a flexible portion of the video content. The flexible portion of the video content may be characterized by a minimum segment duration, a target segment duration, and a maximum segment duration. A duration allocated to the video content may be determined. One or more of the flexible video segments may be selected based on the duration and one or more of the minimum segment duration, the target segment duration, and/or the maximum segment duration of the selected flexible video segments. A video summary including the selected flexible video segments may be generated.
US10783377B2 Visually similar scene retrieval using coordinate data
Aspects of the present disclosure therefore involve systems and methods for identifying a set of visually similar scenes to a target scene selected or otherwise identified by a match analyst. A scene retrieval platform performs operations for: receiving an input that comprises an identification of a scene; retrieving a set of coordinates based on the scene identified by the input, where the set of coordinates identify positions of the entities depicted within the frames; generating a set of vector values based on the coordinates of the entities depicted within each of the frames; concatenating the set of vector values to generate a concatenated vector value that represents the scene; generating a visual representation of the concatenated vector value; and identifying one or more similar scenes to the scene identified by the input based on the visual representation of the concatenated vector value.
US10783371B2 Gabor cube feature selection-based classification method and system for hyperspectral remote sensing images
The present invention provides a Gabor cube feature selection-based classification method for hyperspectral remote sensing images, comprising the following steps: generating three-dimensional Gabor filters according to set frequency and direction parameter values; convoluting hyperspectral remote sensing images with the three-dimensional Gabor filters to obtain three-dimensional Gabor features; selecting three-dimensional Gabor features, classification contribution degrees to various classes of which meet preset requirements, from the three-dimensional Gabor features; and classifying the hyperspectral remote sensing images by a multi-task joint sparse representation-based classification means by using the selected three-dimensional Gabor features. The present invention is based on the three-dimensional Gabor features, and the used three-dimensional Gabor features contain rich local change information of a signal and are competent in feature characterizing. Using a Fisher discriminant criterion not only makes full use of high-level semantics hidden among the features, but also eliminates redundant information and reduces the classification time complexity.
