Patent number: 12262004Abstract: An encoder includes circuitry which generates a first coefficient value by applying a CCALF process to a first reconstructed image sample of a luma component; generates a second coefficient value by applying an ALF process to a second reconstructed image sample of a chroma component; generates a third coefficient value by adding the first coefficient value to the second coefficient value; and encodes a third reconstructed image sample of the chroma component using the third coefficient value. The circuitry writes a first parameter into a sequence parameter set; writes a second parameter into a parameter set of a picture in response to a value of the first parameter being 1; writes a third parameter into a slice header in response to the value of the first parameter being 1; and writes a fourth parameter into a coding tree unit in response to a value of the third parameter being 1.Type: GrantFiled: January 24, 2022Date of Patent: March 25, 2025Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Che-Wei Kuo, Chong Soon Lim, Jing Ya Li, Han Boon Teo, Hai Wei Sun, Chu Tong Wang, Tadamasa Toma, Takahiro Nishi, Kiyofumi Abe, Yusuke Kato

Patent number: 12262038Abstract: A decoder includes circuitry which, in operation, parses a first flag indicating whether a CCALF (cross component adaptive loop filtering) process is enabled for a first block located adjacent to a left side of a current block; parses a second flag indicating whether the CCALF process is enabled for a second block located adjacent to an upper side of the current block; determines a first index associated with a color component of the current block; and derives a second index indicating a context model, using the first flag, the second flag, and the first index. The circuitry, in operation, performs entropy decoding of a third flag indicating whether the CCALF process is enabled for the current block, using the context model indicated by the second index; and performs the CCALF process on the current block in response to the third flag indicating the CCALF process is enabled for the current block.Type: GrantFiled: January 22, 2024Date of Patent: March 25, 2025Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Che-Wei Kuo, Chong Soon Lim, Han Boon Teo, Jing Ya Li, Hai Wei Sun, Chu Tong Wang, Tadamasa Toma, Takahiro Nishi, Kiyofumi Abe, Yusuke Kato

Publication number: 20210341389Abstract: An imager for simultaneously taking full color pictures and fluorescence images from the same perspectives, top-down and side views, is presented that uses multiple cameras looking at the same stage through a beamsplitter and light sources for each view. The imager is configured to work with a particular fluorophore, or at least a predetermined fluorescence excitation wavelength and emission wavelength. A broadband white light source projects through a shortpass or other filter with a cut-off wavelength either lower than or between the excitation and emission wavelengths. Another shortpass or other filter is in front of a color camera with a cut-off wavelength below that of the emission wavelength, while a monochrome fluorescence camera may or may not have additional filters to bring out the fluorescence. These filters may be built into a dichroic mirror of the beamsplitter. In addition, digital processing may boost frequencies in the color image that were dampened by the filters.Type: ApplicationFiled: May 1, 2020Publication date: November 4, 2021Applicant: LI-COR, Inc.Inventors: Han-Wei Wang, Lyle R.

Publication number: 20210259553Abstract: Machine-readable media and computer systems are provided for the highlighting of features in composite images through the alternating of images having complementary colors. An image having a feature of interest is used to generate one or more pseudo color images. A series of a pseudo color images and one or more additional pseudo color or original color images are then alternately displayed so that the differently colored regions among the series of images are easily recognizable to an operator. The differently colored regions differ in having hues that are complementary to one another. The methods are particularly useful for the display of information using two or more imaging modalities and channels, such as is the case for some medical applications in which a natural-light image of pink or light-red tissue with deeper red or blue vasculature is overlaid with another functional image.Type: ApplicationFiled: April 22, 2021Publication date: August 26, 2021Applicant: LI-COR, Inc.Inventor: Han-Wei Wang

Publication number: 20210219843Abstract: Methods and systems are provided for the detecting and presenting of faint signals from a real-time interactive imager. A real-time view of a subject is controlled by a user by entering commands that move the subject or a camera used to record the real-time view. The rate of this movement is monitored, and when the rate descends below a preset value, a trigger is sent to the camera. In response to the trigger, the camera switches to a lower frame frequency for capturing the real-time view of the subject, thereby increasing the amount of light collected in each frame, and increasing the sensitivity of the camera to faint signals. The methods and systems are particularly relevant for surgical or biopsy imaging, in which both a higher frame rate preview image of a subject for 3D visualization, and a higher sensitivity fluorescence image of the subject for tumor margin assessment, are desired.Type: ApplicationFiled: March 26, 2021Publication date: July 22, 2021Applicant: LI-COR, Inc.Inventors: Han-Wei Wang, Lyle R.

Publication number: 20210181110Abstract: Methods for determining surgical margins using an imaging device are described that use multiple cameras to image a biological sample on a turntable bathed in white light or fluorescing due to a systemically administered dye. Fluorescence farther away from an excitation light source can be compensated upon determining a 3-D position of portions of the sample. The turntable is turned and tilted in order to take enough images to prepare an animation of the sample. In a graphical user interface, the animation can be stopped, zoomed, and tilted per a user's gesture, touch, tablet-tilting, or other commands. The image manipulation can be with touch gestures entered using a sterilizable or disposable touch pen.Type: ApplicationFiled: February 17, 2021Publication date: June 17, 2021Applicant: LI-COR, Inc.Inventor: Han-Wei Wang

Patent number: 10775309Abstract: Methods and devices are disclosed for the imaging of a biological sample with a top-down camera and a side-view camera. A biological sample is held on an imaging stage that is capable of rotation in two orthogonal axes. The top-down and side-view cameras can record a series of images of the sample using multiple imaging modalities at different rotational positions of the imaging stage. The top-down camera can be translated along its optical axis to affect the camera zoom and influence the resolution and field of view of the recorded images. Fluorescence excitation light sources can be positioned proximate to each of the top-down and side-view cameras to provide substantially uniform illumination of the sample for imaging with each camera.Type: GrantFiled: June 28, 2019Date of Patent: September 15, 2020Assignee: LI-COR, INC.Inventors: Han-Wei Wang, Lyle R.
