Pen-centric polyline drawing tool
InactiveUS20060262105A1Accurately doneCathode-ray tube indicatorsInput/output processes for data processingFeature dependencyAerospace engineering
A convenient and natural way to draw polyline shapes on a stylus-based computing device is described. A tool or other drawing function relies on a timing mechanism to identify the various vertices in a polyline shape. For example, the endpoint of each line may be detected responsive to the user stopping (or substantially stopping, such as by remaining within a predefined maximum movement threshold) movement of the tip of the stylus relative to the touch-sensitive surface. In addition, feedback is provided indicating that a line and / or its endpoint is about to commit to the polyline shape being drawn. Such feedback may be displayed shortly before the line and / or endpoint actually commits. Upon further delay without substantial movement of the stylus, the line and / or endpoint may then actually commit. A “snap” function is also provided that assists the user in fully closing the polyline shape, if desired.

Removing process-variation-related inaccuracies from scatterometry measurements
ActiveUS20150316490A1Scattering properties measurementsPhotomechanical apparatusMetrologyMeasurement variability
Metrology methods and respective software and module are provided, which identify and remove measurement inaccuracy which results from process variation leading to target asymmetries. The methods comprise identifying an inaccuracy contribution of process variation source(s) to a measured scatterometry signal (e.g., overlay) by measuring the signal across a range of measurement parameter(s) (e.g., wavelength, angle) and targets, and extracting a measurement variability over the range which is indicative of the inaccuracy contribution. The method may further assume certain functional dependencies of the resulting inaccuracy on the target asymmetry, estimate relative donations of different process variation sources and apply external calibration to further enhance the measurement accuracy.

Greedy support vector machine classification for feature selection applied to the nodule detection problem
InactiveUS20050105794A1Character and pattern recognitionPrincipal component analysisCharacteristic space
An incremental greedy method to feature selection is described. This method results in a final classifier that performs optimally and depends on only a few features. Generally, a small number of features is desired because it is often the case that the complexity of a classification method depends on the number of features. It is very well known that a large number of features may lead to overfitting on the training set, which then leads to a poor generalization performance in new and unseen data. The incremental greedy method is based on feature selection of a limited subset of features from the feature space. By providing low feature dependency, the incremental greedy method 100 requires fewer computations as compared to a feature extraction approach, such as principal component analysis.

Method for detecting shielding of road region monitoring video by leaves
The invention belongs to the field of computer vision, and particularly relates to a method for detecting shielding of a road region monitoring video by leaves. Firstly, a Mask R-CNN-based deep learning platform is established for training a network model of a road region and a tree leaf target, and then a detected road region result is optimized to conform to recognition expectation in an urban area video monitoring scene; and secondly, by displaying and understanding a position relation, on a two-dimensional plane, of a three-dimensional space in video monitoring, a judgment result of whether the road region is shielded by the leaves or not is finally obtained according to shielding rules. The method can replace a traditional manual mode of checking a large number of browsing videos oneby one to confirm the shielding by the leaves; the feature dependency with subjective empirical disagreements based on tree leaf area sizes, distribution areas, distances and the like is got rid of; and the shielding perception application of the three-dimensional space is realized by simulation in a two-dimensional space.

Method and system for automatically generating recommendations for a client shopping list
A recommender system for use on a mobile platform or other computing device provides a user with a recommended list of products with default product quantities that are based on prior purchase behavior of the user or customer. This feature relies on analyzing a customer's past purchases and associating a score with each product. The scoring system indicates the statistical likelihood that the customer would want or need to purchase that item on their next order. The customer analysis takes into account, e.g., the number of times a customer has ordered a product, how frequently the product is ordered by the customer, how many days since the respective customers last order and the customers average order size in providing the recommended list of products.
