摘要： One embodiment provides a method, including: capturing, using a camera sensor of an information handling device, an image associated with a user; identifying, in a conferencing application, a background image for a video stream of the user; determining, based on comparing the background image to the image of the user, a contextual discrepancy for a superimposition of the image of the user over the background image; and adjusting, based on the determining, one or more aspects of the background image or one or more aspects of the image of the user to negate the contextual discrepancy. Other aspects are described and claimed.

摘要： A control circuit receives a radiation treatment planning system request for image data to support a particular radiation treatment planning step (typically for a particular corresponding patient). The control circuit then accesses particular image data that is particularly suitable to support the particular radiation treatment planning step and transmits that particular image data in response to the radiation treatment planning system request. Illustrative examples of particular radiation treatment planning steps include, but are not limited to, a contouring step, a segmenting step, a dose prediction step, and a dose calculation step, to note but a few. By one approach, and as one illustrative example, the aforementioned particular image data may comprise patient image information that includes segmented structures.

摘要： An image processing method, an electronic device, and a readable storage medium are provided. The method includes: obtaining an original image; denoising the original image using an image filtering algorithm to form a preprocessed image S; performing contrast enhancement in the preprocessed image S to form a contrast-enhanced image J; adjusting saturation of the contrast-enhanced image J to form an enhanced display image M; sharpening the enhanced display image M to form a sharpened image N; and performing dynamic range enhancement on the sharpened image N using a dynamic range image enhancement algorithm to form an output image. The image processing method, electronic device, and readable storage medium enable multi-level processing on the original image and improve the display accuracy of the output image.

摘要： An image adjustment device includes: an illumination component derivation unit that derives an illumination component of a grayscale image; a reflectance component derivation unit that derives a reflectance component image that is a resulting image in which the illumination component is removed from the grayscale image; a contrast component derivation unit that derives a contrast component based on a contrast value between a pixel of the reflectance component image and a peripheral area of the pixel; a histogram derivation unit that derives a luminance histogram of the grayscale image weighted according to the contrast value for each pixel of the contrast component; a conversion function derivation unit that derives a luminance conversion function for converting a luminance such that a luminance histogram of a converted grayscale image in which the grayscale image is converted by the luminance conversion function and a predetermined histogram are matched with or similar to each other; and a luminance conversion unit that generates the converted grayscale image.

摘要： A system and method are presented for the design and fabrication of arrays of vacuum photodiodes for application to solar power generation. In a preferred embodiment, each photodiode cell comprises a microfabricated enclosure with a hermetically sealed vacuum, an absorptive photocathode, and a transparent anode, wherein the photocathode and the anode are separated by a vacuum gap of less than about 20 micrometers. Light incident on the photocathode through the anode leads to a flux of electrons passing from the photocathode across the vacuum gap to the anode. In a further preferred embodiment, the photocathode is backed by a reflection layer with, e.g., controlled diffuse reflection, thus increasing the efficiency of energy extraction. An array of such cells may be manufactured using automated thin-film deposition and micromachining techniques.

摘要： A system and method for improving a video characteristic of a video stream is described. According to various implementations of the invention, a changed region between a later-in-time image frame and an earlier-in-time image frame and an unchanged region between such two image frames are determined. A new improvement to the video characteristic is determined and applied to the changed region of the later-in-time image frame. A prior improvement to the video characteristic that was determined for the earlier-in-time image frame is applied to the unchanged region of the later-in-time image frame.

摘要： A control apparatus includes: a control unit that controls an image capturing device and an illumination device that includes multiple light sources, and obtains a first number of reference images corresponding to the first number of the light sources being less than the multiple light sources; and a generation unit that generates correction data for correcting illuminance unevenness of a target image based on the first number of the reference images, which is obtained by capturing an image of a measurement target object different from the reference object while turning on a light source of interest out of the multiple light sources. The generation unit generates the correction data corresponding to a light source not included in the first number of the light sources by carrying out interpolation processing while using at least two reference images out of the first number of the reference images.
