摘要： A transcoder includes a direct transcoder that generates a first portion of a transcoded video stream by reusing a plurality of encoding parameters of a compressed video stream. A cascaded transcoder generates a second portion of the transcoded video stream by decoding the compressed video stream into video data in an uncompressed video format and by re-encoding the video data. A transcoding decision generator generates a transcoding indicator, based on the compressed video stream. A switching module selects the direct transcoder for the first portion of the transcoded video stream and the cascaded transcoder for the second portion of the transcoded video stream, based on the transcoding indicator.

摘要： An imaging and display system for guiding medical interventions includes a wearable display, such as a goggle display, for viewing by a user. The display presents a composite, or combined image that includes pre-operative surgical navigation images, intraoperative images, and in-vivo microscopy images or sensing data. The pre-operative images are acquired from scanners, such as MRI and CT scanners, while the intra-operative images are acquired in real-time from a camera system carried by the goggle display for imaging the patient being treated so as to acquire intraoperative images, such as fluorescence images. A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.

摘要： A system for using radio frequency (RF) communication signals to extract situational awareness information thorough deep learning. Pre-processing is performed to maximally preserve discriminating features in spatial, temporal and frequency domains. A specially designed neural network architecture is used for handling complex RF signals and extracting spatial, temporal and frequency domain information. Data collection and training is used so that the learning system desensitizes from features orthogonal to the underlying classification problem.
