Abstract

This disclosure provides methods, devices, and systems for data compression. The present implementations more specifically relate to encoding techniques for compressing probability tables used for entropy coding. In some aspects, an entropy encoder may encode a probability table so that one or more contexts are represented by fewer bits than would otherwise be needed to represent the frequency of each symbol as a proportion of the total frequency of all symbols associated with such contexts. For example, if a given row of the probability table (prior to encoding) includes a number (M) of entries each having a binary value represented by a number (K) of bits, the same row of entries may be represented by fewer than M*K bits in the encoded probability table.

Abstract

Systems and method for streaming video content include downscaling video content using a downscaling model to generate downscaled video content and downloading the downscaled video content as a video stream and corresponding upscaling model to a client device. The system converts received video frames to a video memory format comprising channels having the same memory allocation size, each subsequent channel arranged in an adjacent memory location, for input to the downscaling model. The client device upscales the video stream using the received upscaling model for display by the client device in real-time. A training system trains the downscaling model to generate the downscaled video content, based on associated metadata identifying a type of video content. The downscaled video content and associated upscaling models are stored for access by an edge server, which downloads upscaling models to a client device to select an upscaling model.

Abstract

This disclosure provides methods, devices, and systems for image compression. The present implementations more specifically relate to image compression techniques that support inter-channel encoding of codewords. An encoder implementing an image compression operation may apply a spatial-frequency transform to a number (N) arrays of pixel values associated with N color channels, respectively, and may quantize the result to produce N arrays of quantized coefficients. In some aspects, the encoder may map each quantized coefficient of the N arrays of quantized coefficients to a data structure and may encode the data structure as one or more codewords associated with a lossless compression scheme. In some implementations, the mapping may arrange the quantized coefficients in the data structure in order of decreasing (or increasing) amplitude, independent of color channel.

Abstract

This disclosure provides methods, devices, and systems for data compression. The present implementations more specifically relate to lossless data compression techniques that combine entropy coding with run-length encoding of zeroes. In some aspects, an encoder may obtain a sequence of integer values representing a frame of data and may iteratively scan the sequence for runs of zeros. During each iteration of the scan, the encoder may increment a count value (N) if the current integer value is equal to zero or, if the current integer value is not equal to zero, output a pattern of bits representing the current count value or the current integer value. In some implementations, the pattern of bits may include a codeword associated with an entropy encoding scheme. More specifically, the encoder may encode the current integer value as the codeword if N>0 and may encode the current count value as the codeword if N=0.

Abstract

An apparatus for remote processing of raw image data receives the raw image data from a camera, such as a security camera. The apparatus includes a detection module to detect portions of the image data that contain possible regions of interest. Information indicating the portions that contain the possible regions of interest is then used during a compression process so that the portions that contain the possible regions of interest are compressed using one or more compression algorithms to facilitate further analysis and the remainder are treated differently. The compressed image data is then transmitted to a central system for decompression and further analysis. In some cases, the detection system may detect possible regions of interest which appear to be faces, but without performing full facial recognition. These parts of the image data are then compressed in such a way as to maintain as much facial detail as possible, so as to facilitate the facial recognition when it is carried out at the central server. The detection may be performed on the raw image data or may be performed as part of the compression process after a transformation of the raw image data has been carried out.

The color palette transitions are in proportional time segments of a twenty-four hour day punctuated by periods of light and darkness of variable length corresponding to the revolution of the earth around the sun. A collection of gaze points is formed in the digital space. Each gaze point in the collection experiences cyclic changes between a minimum position and a maximum position during a gaze point size change cycle. Initially, each gaze point in the collection experiences different changes between the minimum position and the maximum position during initial gaze point size change cycles thereby forming a gaze point out-of-phase period. Subsequently, selected gaze points in the collection experience common changes between the minimum position and the maximum position during intermediate gaze point size change cycles thereby forming a gaze point hybrid phase period. Finally, all gaze points in the collection share common changes between the minimum position and the maximum position during final gaze point size change cycles thereby forming a gaze point in-phase period that lasts at least one half the time period of less than six minutes.

The present implementations more specifically relate to selecting images that can be used for training a neural network to infer denoised representations of images captured in low light conditions. In some aspects, a machine learning system may obtain a series of images of a given scene, where each of the images is associated with a different SNR (representing a unique combination of exposure and gain settings). The machine learning system may identify a number of saturated pixels in each image and classify each of the images as a saturated image or a non-saturated image based on the number of saturated pixels. The machine learning system may then select the non-saturated image with the highest SNR as the ground truth image, and the non-saturated images with lower SNRs as the input images, to be used for training the neural network.

Abstract

An input-display device includes a display screen with display pixels, capacitive sensing electrodes for capacitive sensing in a sensing region of the display screen, and a gate driver circuit associated with the display screen. The gate driver circuit superimposes a critical time window on a full-duration gate control pulse of a gate control signal. The critical time window partially overlaps with the full-duration gate control pulse at least at an end of the full-duration gate control pulse. The gate driver circuit further determines that a transient in a sensing waveform of the capacitive sensing occurs in the critical time window superimposed on the full-duration gate control pulse, and based on the determination, shorten the full-duration gate control pulse to obtain a reduced-duration gate control pulse. The gate driver circuit provides the reduced-duration gate control pulse to a pixel circuit of one of the display pixels.
