Patent number: 11818495Abstract: A method of producing an image frame from event packets received from an event camera comprises: forming a tile buffer sized to accumulate event information for a subset of image tiles, the tile buffer having an associated tile table that determines a mapping between each tile of the image frame for which event information is accumulated in the tile buffer and the image frame. For each event packet: an image tile corresponding to the pixel location of the event packet is identified; responsive to the tile buffer storing information for one other event corresponding to the image tile, event information is added to the tile buffer; and responsive to the tile buffer not storing information for another event corresponding to the image tile and responsive to the tile buffer being capable of accumulating event information for at least one more tile, the image tile is added to the tile buffer.Type: GrantFiled: June 28, 2022Date of Patent: November 14, 2023Inventors: Lorant Bartha, Corneliu Zaharia, Vlad Georgescu, Joe Lemley

Patent number: 11593913Abstract: A method for correcting an image divides an output image into a grid with vertical sections of width smaller than the image width but wide enough to allow efficient bursts when writing distortion corrected line sections into memory. A distortion correction engine includes a relatively small amount of memory for an input image buffer but without requiring unduly complex control. The input image buffer accommodates enough lines of an input image to cover the distortion of a single most vertically distorted line section of the input image. The memory required for the input image buffer can be significantly less than would be required to store all the lines of a distorted input image spanning a maximal distortion of a complete line within the input image.Type: GrantFiled: June 6, 2022Date of Patent: February 28, 2023Inventors: Piotr Stec, Vlad Georgescu

Patent number: 11106894Abstract: An image processing apparatus comprises a normalisation module operatively connected across a bus to a memory storing an image in which a region of interest (ROI) has been identified within the image. The ROI is bound by a rectangle having a non-orthogonal orientation within the image. In one embodiment, the normalisation module is arranged to divide the ROI into one or more slices, each slice comprising a plurality of adjacent rectangular tiles. For each slice, the apparatus successively reads ROI information for each tile from the memory including: reading a portion of the image extending across at least a width of the slice line-by-line along an extent of a slice. For each tile, the apparatus downsamples the ROI information to a buffer to within a scale SD<2 of a required scale for a normalised version of the ROI.Type: GrantFiled: October 25, 2018Date of Patent: August 31, 2021Assignee: FotoNation LimitedInventors: Vlad Georgescu, Mihai Constantin Munteanu, Petronel Bigioi, Corneliu Zaharia, Szabolcs Fulop, Gyorgy Simon

Patent number: 10839247Abstract: A method for producing a histogram of oriented gradients (HOG) for at least a portion of an image comprises dividing the image portion into cells, each cell comprising a plurality of image pixels. Then, for each image pixel of a cell, obtaining a horizontal gradient component, gx, and a vertical gradient component, gy, based on differences in pixel values along at least a row of the image and a column of the image respectively including the pixel; and allocating a gradient to one of a plurality of sectors, where n is a sector index, each sector extending through a range of orientation angles and at least some of the sectors being divided from adjacent sectors according to the inequalities: b*16<a*(n+1) where 0?n?5, b=gy and a=gx; and b*16<a*(13?n) where 7?n?12, a=gx+gy and b=gx?gy. At least one sector is associated with a bin; and each instance of a pixel gradient of a cell associated with a bin is accumulated to provide a HOG for the cell.Type: GrantFiled: May 19, 2017Date of Patent: November 17, 2020Assignee: FotoNation LimitedInventors: Mihai Constantin Munteanu, Vlad Georgescu, Corneliu Zaharia, Iulia Suciu

Patent number: 10235639Abstract: In a crowd sourcing approach, responses to customer service inquiries are provided by routing the inquiries to an independent group of experts. Machine learning based systems are used in combination with contact center staff and/or the independent experts to resolve the customer service inquiries. The AI based systems can be configured to determine which of the customer service inquiries should be routed to the independent experts, and/or to generate content for inclusion in responses to the customer service inquiries. The machines systems are optionally trained based on scored responses to prior customer service inquiries. These scored responses can include content provided by a machine learning system and/or a human expert.Type: GrantFiled: March 31, 2017Date of Patent: March 19, 2019Assignee: Directly Software, Inc.Inventors: Eugene Mandel, Vlad Georgescu, Jeff Patterson, Antony Fenwick Brydon, Jason Fama, Scott Golubock, Jean Tessier, Stephen Hsu
