Patent number: 10540537Abstract: A method for content detection based on images or a digital video stream of images, to enhance and isolate frequency domain signals representing content to be identified, and decrease or ignore frequency domain noise with respect to the content. A digital image or sequence of digital images defined in a spatial domain are obtained. One or more pairs of sparse zones are selected, each pair generating a feature, each zone defined by two sequences of spatial data. The selected features are transformed into frequency domain data. The transfer function, shape and direction of the frequency domain data are varied for each zone, thus generating a normalized complex vector for each feature. The normalized complex vectors are then combined to define a model of the content to be identified.Type: GrantFiled: February 19, 2018Date of Patent: January 21, 2020Assignee: COGISEN S.R.L.Inventor: Christiaan Erik Rijnders

Patent number: 10467472Abstract: A system for identifying ponding water located on a field from image data is described. In an approach, an image of an agricultural field is analyzed using a classifier that has been trained based on the spectral bands of labeled image pixels to identify a probability for each pixel within the image that the pixel corresponds to water. A flow simulation is performed to determine regions of the field that are likely to pool water after rainfall based on precipitation data, elevation data, and soil property data of the field. A graph of vertices representing the pixels and edges representing connections between neighboring pixels is generated. The probability of each pixel within the graph being ponding water is set based on the probability pixel being water, the likelihood that water will pool in the area represented by the pixel, the probability of neighboring pixels being ponding water, and a cropland mask that identifies which pixels correspond to cropland.Type: GrantFiled: July 17, 2018Date of Patent: November 5, 2019Assignee: THE CLIMATE CORPORATIONInventors: Wei Guan, Pramithus Khadka

Patent number: 10467484Abstract: A driver-fatigue warning system suitable for use in an automated vehicle includes a camera, an alert-device, and a controller. The camera renders an image of a lane-marking and of an object proximate to a host-vehicle. The alert-device is operable to alert an operator of the host-vehicle of driver-fatigue. The controller is in communication with the camera and the alert-device. The controller determines a vehicle-offset of the host-vehicle relative to the lane-marking based on the image. The controller determines an offset-position of the object relative to the lane-marking based on the image. The controller determines that a lane-departure has occurred when the vehicle-offset is less than a deviation-threshold. The controller does not count occurrences of lane-departures when the offset-position is less than an offset-threshold, and activates the alert-device when the count of the occurrences of lane-departures exceeds a crossing-threshold indicative of driver-fatigue.Type: GrantFiled: June 1, 2017Date of Patent: November 5, 2019Assignee: APTIV TECHNOLOGIES LIMITEDInventor: Premchand Krishna Prasad

Patent number: 10432946Abstract: Judder artifacts are remedied in video coding system by employing frame rate conversion at an encoder. A source video sequence may be coded as base layer coded video at a first frame rate. An encoder may identify a portion of the coded video sequence that likely will exhibit judder effects when decoded. For those portions that likely will exhibit judder effects, video data representing the portion of the source video may be coded at a higher frame rate than a frame rate of the coded base layer data as enhancement layer data. Moreover, an encoder may generate metadata representing “FRC hints”—techniques that a decoder should employ when performing decoder-side frame rate conversion. An encoding terminal may transmit the base layer coded video and either the enhancement layer coded video or the FRC hints to a decoder. Thus, encoder infrastructure may mitigate against judder artifacts that may arise during decoding.Type: GrantFiled: December 10, 2015Date of Patent: October 1, 2019Assignee: Apple Inc.Inventors: Yeping Su, Chris Y.
