Publication number: 20190005659Abstract: Apparatus and methods for detecting and utilizing saliency in digital images. In one implementation, salient objects may be detected based on analysis of pixel characteristics. Least frequently occurring pixel values may be deemed as salient. Pixel values in an image may be compared to a reference. Color distance may be determined based on a difference between reference color and pixel color. Individual image channels may be scaled when determining saliency in a multi-channel image. Areas of high saliency may be analyzed to determine object position, shape, and/or color. Multiple saliency maps may be additively or multiplicative combined in order to improve detection performance (e.g., reduce number of false positives). Methodologies described herein may enable robust tracking of objects utilizing fewer determination resources. Efficient implementation of the methods described below may allow them to be used for example on board a robot (or autonomous vehicle) or a mobile determining platform.Type: ApplicationFiled: August 17, 2018Publication date: January 3, 2019Inventors: Filip Piekniewski, Micah Richert, Dimitry Fisher

Publication number: 20180278820Abstract: An optical object detection apparatus and associated methods. The apparatus may comprise a lens (e.g., fixed-focal length wide aperture lens) and an image sensor. The fixed focal length of the lens may correspond to a depth of field area in front of the lens. When an object enters the depth of field area (e.g., sue to a relative motion between the object and the lens) the object representation on the image sensor plane may be in-focus. Objects outside the depth of field area may be out of focus. In-focus representations of objects may be characterized by a greater contrast parameter compared to out of focus representations. One or more images provided by the detection apparatus may be analyzed in order to determine useful information (e.g., an image contrast parameter) of a given image. Based on the image contrast meeting one or more criteria, a detection indication may be produced.Type: ApplicationFiled: December 18, 2017Publication date: September 27, 2018Inventors: Filip Piekniewski, Vadim Polonichko, Eugene Izhikevich

Patent number: 9552546Abstract: Apparatus and methods for plasticity in spiking neuron networks. In various implementations, the efficacy of one or more connections of the network may be adjusted based on a plasticity rule during network operation. The rule may comprise a connection depression portion and/or a potentiation portion. Statistical parameters of the adjusted efficacy of a population of connections may be determined. The statistical parameter(s) may be utilized to adapt the plasticity rule during network operation in order to obtain efficacy characterized by target statistics. Based on the statistical parameter exceeding a target value, the depression magnitude of the plasticity rule may be reduced. Based on a statistical parameter being below the target value, the depression magnitude of the plasticity rule may be increased. The use of adaptive modification of the plasticity rule may improve network convergence while alleviating a need for manual tuning of efficacy during network operation.Type: GrantFiled: July 30, 2013Date of Patent: January 24, 2017Assignee: Brain CorporationInventor: Filip Piekniewski

Patent number: 9460385Abstract: Apparatus and methods for activity based plasticity in a spiking neuron network adapted to process sensory input. In one approach, the plasticity mechanism of a connection may comprise a causal potentiation portion and an anti-causal portion. The anti-causal portion, corresponding to the input into a neuron occurring after the neuron response, may be configured based on the prior activity of the neuron. When the neuron is in low activity state, the connection, when active, may be potentiated by a base amount. When the neuron activity increases due to another input, the efficacy of the connection, if active, may be reduced proportionally to the neuron activity. Such functionality may enable the network to maintain strong, albeit inactive, connections available for use for extended intervals.Type: GrantFiled: August 22, 2014Date of Patent: October 4, 2016Assignee: QUALCOMM TECHNOLOGIES INC.Inventors: Filip Piekniewski, Micah Richert, Eugene Izhikevich, Victor Hokkiu Chan, Jeffrey Alexander Levin

Patent number: 9436909Abstract: Apparatus and methods for processing inputs by one or more neurons of a network. The neuron(s) may generate spikes based on receipt of multiple inputs. Latency of spike generation may be determined based on an input magnitude. Inputs may be scaled using for example a non-linear concave transform. Scaling may increase neuron sensitivity to lower magnitude inputs, thereby improving latency encoding of small amplitude inputs. The transformation function may be configured compatible with existing non-scaling neuron processes and used as a plug-in to existing neuron models. Use of input scaling may allow for an improved network operation and reduce task simulation time.Type: GrantFiled: June 19, 2013Date of Patent: September 6, 2016Assignee: Brain CorporationInventors: Filip Piekniewski, Vadim Polonichko, Eugene Izhikevich

Patent number: 9373038Abstract: A data processing apparatus may utilize an artificial neuron network configured to reduce dimensionality of input data using a sparse transformation configured using receptive field structure of network units. Output of the network may be analyzed for temporally persistency that is characterized by similarity matrix. Elements of the matrix may be incremented when present activity unit activity at a preceding frame. The similarity matrix may be partitioned based on a distance measure for a given element of the matrix and its closest neighbors. Stability of learning of temporally proximal patterns may be greatly improved as the similarity matrix is learned independently of the partitioning operation. Partitioning of the similarity matrix using the methodology of the disclosure may be performed online, e.g., contemporaneously with the encoding and/or similarity matrix construction, thereby enabling learning of new features in the input data.Type: GrantFiled: February 26, 2014Date of Patent: June 21, 2016Assignee: Brain CorporationInventors: Micah Richert, Filip Piekniewski

Patent number: 9275326Abstract: Apparatus and methods for activity based plasticity in a spiking neuron network adapted to process sensory input. In one embodiment, the plasticity mechanism may be configured for example based on activity of one or more neurons providing feed-forward stimulus and activity of one or more neurons providing inhibitory feedback. When an inhibitory neuron generates an output, inhibitory connections may be potentiated. When an inhibitory neuron receives inhibitory input, the inhibitory connection may be depressed. When the inhibitory input arrives subsequent to the neuron response, the inhibitory connection may be depressed. When input features are unevenly distributed in occurrence, the plasticity mechanism is capable of reducing response rate of neurons that develop receptive fields to more prevalent features. Such functionality may provide network output such that rarely occurring features are not drowned out by more widespread stimulus.Type: GrantFiled: November 30, 2012Date of Patent: March 1, 2016Assignee: Brain CorporationInventors: Filip Piekniewski, Micah Richert, Dimitry Fisher, Eugene Izhikevich
