Abstract: This disclosure provides methods, devices, and systems for object detection. The present implementations more specifically relate to techniques for improving distant object detection in memory-constrained computer vision systems. In some aspects, a computer vision system may include an ROI extraction component, a feature pyramid network (FPN) having a number (N) of pyramid levels, and N network heads associated with the N pyramid levels, respectively. The FPN extracts N feature maps from an input image, where the N feature maps are associated with the N pyramid levels, respectively, and each of the N network heads performs an object detection operation on a respective feature map of the N feature maps. The ROI extraction component selects a region of the feature map associated with the lowest pyramid level for distant object detection so that the object detection operation performed on that feature map is confined to the selected region.

Abstract: This disclosure provides methods, devices, and systems for transmitting and receiving image data. The present implementations more specifically relate to repurposing non-video interfaces to receive image data. In some aspects, an image processing device may be coupled to an image source via an audio interface. For example, the audio interface may be an inter-IC sound (I2S) serial bus interface having at least a serial data input and a word select (WS) input. In some implementations, the serial data input may be coupled to receive image data from the image source and the WS input may be coupled to receive a WS signal that tracks a horizontal synchronization (HSYNC) signal associated with the image data. Accordingly, the image processing device may capture (or store) frames of received image data, where the beginning of each frame is aligned with an edge of the WS signal (and thus, the HSYNC signal).

Abstract: A method performed by a docking station operable in a plurality of modes is disclosed. The method may include obtaining first data via a first interface of the docking station and second data via a second interface of the docking station, responsive to operating in a first mode of the plurality of modes. The first interface may be configured to couple the docking station to a computing device, and the second interface may be configured to communicate with a network. The method may also include obtaining third data via the second interface of the docking station, in lieu of the first interface, responsive to operating in a second mode of the plurality of modes. The method may further include selectively outputting the first data and the second data, or the third data, to a display based on whether the docking station operates in the first mode or the second mode.

Abstract: A system and method for capacitive sensing using an input device are provided. The input device includes a display, a touch sensor and a processing system. The touch sensor has a plurality of transmitter electrodes with a first subset of positive transmitter electrodes driven by a positive sensing signal and a second subset of negative transmitter electrodes driven by a negative sensing signal. Each positive transmitter electrode spatially alternates with a negative transmitter electrode of the second subset of negative transmitter electrodes. The touch sensor includes a plurality of receiver electrodes arranged in differential pairs. Each differential pair includes a positive receiver electrode coupled to at least one of the first subset of positive transmitter electrodes and a negative receiver electrode coupled to at least one of the second subset of negative transmitter electrodes. The processing system transmits the positive sensing signal and the negative sensing signal, and receives a first resulting signal from the positive receiver electrode and a second resulting signal from the negative receiver electrode. The first resulting signal and the second resulting signal are combined to mitigate noise.

Abstract: This disclosure provides methods, devices, and systems for audio signal processing. The present implementations more specifically relate to speech enhancement techniques that combine statistical signal processing with neural network inferencing. In some aspects, a speech enhancement system may include a linear filter, a deep neural network (DNN), and a nonlinear post-filter. The linear filter and the nonlinear post-filter are configured to suppress noise in audio signals using statistical signal processing techniques. More specifically, the linear filter denoises an input audio signal based on a temporal correlation between successive frames of the audio signal. The DNN infers a speech signal and a noise signal (representing a speech component and a noise component, respectively, of the audio signal) based on the denoised audio signal. The nonlinear post-filter suppresses residual noise in the speech signal based on one or more Gaussian mixture models (GMM) associated with the speech signal and the noise signal.

Abstract: This disclosure provides methods, devices, and systems for audio signal processing. The present implementations more specifically relate to speech enhancement techniques that utilize multi-channel audio signals for audio source classification. In some aspects, a speech enhancement system may include an adaptive filter, a feature extractor, and a feature classifier. The adaptive filter is configured to receive a multi-channel audio signal, via at least a first microphone and a second microphone, and determine a relative impulse response (ReIR) between the microphones based on the multi-channel audio signal. The feature extractor is configured to extract a set of features from the ReIR based at least in part on a peak of the ReIR. The feature classifier is configured to classify the set of features as being associated with a target source or a distractor source based on a Gaussian mixture model (GMM).

Abstract: This disclosure provides methods, devices, and systems for audio signal processing. The present implementations more specifically relate to low-latency speech enhancement. In some aspects, a speech enhancement system may receive a number (B) of frames of a signal, where each of the B frames include a number (N) of time-domain samples. The speech enhancement system may transform the B*N time-domain samples into B*N first frequency-domain samples based on an N-point fast Fourier transform (FFT), and may further transform the B*N first frequency-domain samples into B*N second frequency-domain samples based on a B-point FFT. The speech enhancement system may determine a probability of speech in the signal based at least in part on the B*N second frequency-domain samples. In some implementations, the speech enhancement system may decimate the B*N second frequency-domain samples by a factor (D), and the probability of speech is determined based on the B*N/D decimated second frequency-domain samples.
