  • Publication number: 20240169533
    Abstract: A method for calculating parameters in a larynx image with an artificial intelligence assistance includes training a deep learning object detection software and a deep learning image recognition and segmentation software to extract a glottis image from a larynx image and recognize a membranous glottal gap; after receiving a larynx image, a plurality of larynx images captured frame-by-frame, or a larynx video that is captured when vocal folds are in a phonating state, extracting a glottis image by the deep learning object detection software; recognizing a membranous glottal gap in the glottis image and correspondingly outputting a membranous glottal gap filter by the deep learning image recognition and segmentation software; performing image processing of edge detection and image patching on the membranous glottal gap filter to clearly outline the membranous glottal gap and obtaining a medical parameter of several vocal fold anatomies from the clearly outlined membranous glottal gap.

  • Patent number: 7765598
    Abstract: The present invention discloses a method of online detecting MP3 music transmissions and an architecture thereof, wherein the packets transmitted over network segments are intercepted by an MP3 packet sniffing technology; the feature values of the MP3 packets are extracted out via an MP3 music feature value extraction technology and then compared with an MP3 feature value database, and thereby, the IP addresses of the sender and the receiver, which perform an illegal MP3 transmission, are detected and recorded in order to implement investigation and protect intellectual property.

  • Patent number: 6658019
    Abstract: In a wireless video transmission method for transmitting a video stream on wireless communication networks, the video stream is classified into at least two classes of sensitivity, each corresponding to a sensitive class of data. Each sensitive class of data is optionally advanced an ahead time for starting transmission based on the corresponding class of sensitivity. Then, an automatic repeat of data is optionally applied on each sensitive class of data based on the corresponding class of sensitivity, thereby providing an enhanced error protective capability and reducing the transmission delay.

  • Patent number: 5819286
    Abstract: A video indexing and query execution system includes a processor which indexes video clips by: (a) identifying each symbol of one or more graphical icons in each frame of each video clip, (b) determining the horizontal, vertical and temporal coordinates of each symbol of the identified graphical icons, and (c) constructing a database for each identified symbol of the graphical icons. The processor converts a video query from graphical form to string form by: (a) receiving a video query specifying the vertical, horizontal and temporal coordinates of a graphical icon to be matched in at least one frame to be retrieved, and (b) constructing a normal 3-D string from the video query indicating the distance between each symbol of each icon in the video query in each direction.
