  • Can you read me now? Content aware rectification using angle supervision
    Amir Markovitz, Inbal Lavi, Or Perel, Shai Mazor, Roee Litman
    ECCV 2020
    2020
    The ubiquity of smartphone cameras has led to more and more documents being captured by cameras rather than scanned. Unlike flatbed scanners, photographed documents are often folded and crumpled, resulting in large local variance in text structure. The problem of document rectification is fundamental to the Optical Character Recognition (OCR) process on documents, and its ability to overcome geometric distortions

  • CAM: Uninteresting speech detector
    Weiyi Lu, Yi Xu, Peng Yang, Belinda Zeng
    Interspeech 2020
    2020
    Voice assistants such as Siri, Alexa, etc. usually adopt a pipeline to process users’ utterances, which generally include transcribing the audio into text, understanding the text, and finally responding back to users. One potential issue is that some utterances could be devoid of any interesting speech, and are thus not worth being processed through the entire pipeline. Examples of uninteresting utterances

    Many modern smart building applications are supported by wireless sensors to sense physical parameters, given the flexibility they offer and the reduced cost of deployment. However, most wireless sensors are powered by batteries today and large deployments are inhibited by the requirement of periodic battery replacement. Energy harvesting sensors provide an attractive alternative, but they need to provide

    2020
    Small footprint embedded devices require keyword spotters (KWS) with small model size and detection latency for enabling voice assistants. Such a keyword is often referred to as wake word as it is used to wake up voice assistant enabled devices. Together with wake word detection, accurate estimation of wake word endpoints (start and end) is an important task of KWS. In this paper, we propose two new methods

    Interspeech 2020
    2020
    Wakeword detection is responsible for switching on downstream systems in a voice-activated device. To prevent a response when the wakeword is detected by mistake, a secondary network is often utilized to verify the detected wakeword. Published verification approaches are formulated based on Automatic Speech Recognition (ASR) biased towards the wakeword. This approach has several drawbacks, including high
