Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated by a backlight unit that includes an array of light-emitting diodes (LEDs). The backlight unit may determine the type of content in the image data. The backlight unit may decide to prioritize either mitigating halo or mitigating clipping based on the type of content. The determination of the type of content in the image data may be used to determine the brightness values for the LEDs in the LED array. If the content is determined to be a first type of content, at least one given LED in the LED array may have a different brightness value than if the content is determined to be a second, different type of content. Classifying content in the image data may be useful in optimizing visible artifacts such as visible halo and clipping.

Abstract: A mobile robot map construction method and apparatus, and a computer device and a storage medium. The mobile robot map construction method comprises: acquiring the number of floors and current floor information (S202); acquiring point cloud data of an environment around the current location by means of a laser radar, acquiring image data of the environment around the current location by means of a camera, and constructing an environment map according to the point cloud data and the image data and labeling a glass location (S204); determining whether there is an area to be detected in the environment map, and if there is an area to be detected, detecting said area according to a pre-set rule (S206); and if there is no area to be detected, moving to the nearest elevator in an obstacle avoidance mode according to an elevator location marked on the environment map, and taking the elevator to an undetected floor until environment map construction of all undetected floors is completed (S208).

Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system comprises: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further comprises a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: A compound represented by formula (I), an optical isomer thereof and a pharmaceutically acceptable salt thereof, as well as an application of said compound as an FXIa inhibitor.

Abstract: Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.
