摘要： A method, device and computer-readable medium for generating a super-resolution version of a compressed video stream. By leveraging the motion information and residual information in compressed video streams, described examples are able to skip the time-consuming motion-estimation step for most frames and make the most use of the SR results of key frames. A key frame SR module generates SR versions of I-frames and other key frames of a compressed video stream using techniques similar to existing multi-frame approaches to VSR. A non-key frame SR module generates SR version of the non-key inter frames between these key frames by making use of motion information and residual information used to encode the inter frames in the compressed video stream.

摘要： Devices and methods for extracting motion vector data during decoding compressed of video data are described. At a video decoder, an encoded video data for a frame of video from an input buffer is obtained. The encoded video data is decoded to obtain decoded image data for a decoded frame, where the decoding includes extracting corresponding motion vector data for the decoded frame. The decoded image data is stored in a temporary storage indexed with a given index, and the corresponding motion vector data is stored in a same or different temporary storage indexed with the given index. An output buffer indexed with the given index is filled with the decoded image data and the corresponding motion vector data stored in the respective temporary storage indexed with the given index.

摘要： Methods, devices and computer-readable media for processing a compressed video to perform an inference task are disclosed. Processing the compressed video may include selecting a subset of frame encodings of the compressed video, or zero or more modalities (RGB, motion vectors, residuals) of a frame encoding, for further processing to perform the inference task. Pre-existing motion vector and/or residual information in frame encodings of the compressed video are leveraged to adaptively and efficiently perform the inference task. In some embodiments, the inference task is an action recognition task, such as a human action recognition task.

摘要： Methods and systems for image deblurring are described. The weights of a deblurring network are first trained by meta-training the deblurring network on both a primary deblurring task and an auxiliary reconstruction task. Application-time training of the deblurring network is then performed, using an application-time blurry input image, to obtain values of application-time trained weights. Application-time training includes performing the auxiliary reconstruction task on the application-time blurry input image, and updating the weights of the deblurring network based on an auxiliary loss computed from the auxiliary reconstruction task. A deblurred output image is generated from the application-time blurry input image, using the application-time trained weights in the deblurring network.

摘要： Systems, methods and computer-readable medium for predicting a depth for a video frame are disclosed. An example method may include steps of: receiving a plurality of training data, each comprising a set of consecutive video frames and a depth representation of a subsequent video frame to the consecutive video frames; receiving a pre-trained neural network model fθ having a plurality of weights θ; while the pre-trained neural network model fθ has not converged: computing a plurality of second weights θi′, based on each set of consecutive video frames, and updating the plurality of weights θ, based on the plurality of training data and the plurality of second weights θi′; receiving a plurality of new consecutive video frames with consecutive timestamps; and predicting a depth representation of video frame immediately subsequent to the new consecutive video frames based on the updated plurality of weights θ.

摘要： An electrical system can selectively power a load via a USB connection or via another power source, such as a wireless power transfer path. An integrated switch controller determines whether to power the load via the USB connection or the other power sources and controls two external transistors via a single I/O pin connection to implement that determination. The switch controller determines the greater of two voltages: a voltage associated with the USB connection and a voltage associated with the other power source. The switch controller also determines whether there is a valid USB connection. The switch controller circuitry that controls the two external transistors is powered at the greater voltage to ensure that the external transistors are appropriately and securely turned on or off.

摘要： A voltage supply for providing a clamped voltage to a circuit element to be protected against electrical overstress (EOS) has a reference voltage module and a voltage clamp module. The reference voltage module has a first field-effect transistor (FET) whose source and drain are connected in series between a programmable reference current source and a first resistor across a power supply. The gate of the first FET is connected to its drain to provide a reference voltage defined by the reference current flowing in the first resistor. The voltage clamp module has a second FET whose gate receives the reference voltage and whose source is connected to provide to the protected circuit element the clamped voltage whose variation is limited by the reference voltage.

摘要： A true random number generator (RNG) has one or more oscillators and an output register for storing a random number output. Each of the oscillators is activated, successively, in a free-running oscillation phase, and a capture phase during which the oscillator is quiescent. The output register latches during the capture phase of each oscillator an end state of that oscillator at or close to the end of its oscillation phase. The random number output is derived from the latched end states.
