  • Publication number: 20210196238
    Abstract: In an ultrasound imaging system which produces synthetically transmit focused images, the multiline signals used to form image scanlines are analyzed for speed of sound variation, and a map 60 of this variation is generated. In a preferred implementation, the phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the angular spectrum domain for the receive angular spectrum. Once the phase is estimated for all locations in an image, the differential phase between two points at the same lateral location, but different depth, is computed. This differential phase is proportional to the local speed of sound between the two points. A color-coded two- or three-dimensional map 60 is produced from these speed of sound estimates and presented to the user.

  • Publication number: 20210185332
    Abstract: Method and apparatus of coding a video sequence, are disclosed. According to the method, a bitstream corresponding to encoded data of the video sequence is generated at an encoder side or received at a decoder side, where the bitstream complies with a bitstream conformance that one or more constraints are satisfied. The constraints are related to a set of RPR (Reference Picture Resampling) parameters including scaling window width or height of a current picture, scaling window width or height of a reference picture, current picture width or height, and maximum picture width or height specified for the video sequence. Scaling information for the RPR mode is derived using the set of RPR parameters.
