摘要： A system and method for registering images captured by a camera of heliostats in a heliostat field for use in tracking control of the heliostats is disclosed. The method includes calculating a geographical location of a reflection of the sun on a reflective dome surface of fiducial markers positioned relative to the heliostat field that are in a field of view of the camera, the geographical location calculated based on a location of the sun at a time corresponding to a time-stamp of the captured image, a geographical location and a radius of the reflective dome of the fiducial markers, and a geographical location of the viewing camera. A correct mapping of the fiducial markers in the captured image is identified. Optionally, an affine transform is applied to the captured image via rotation and translation so that pixels in the transformed image for the fiducial markers map to geographical coordinates of the fiducial markers.

摘要： The image processing system includes a scanner, a pixelated photon detector (PPD), and at least one processor. The at least one processor displays a setting screen on a display unit. The setting screen is a screen for setting an identification range that is a range of gradation to be identified. The at least one processor displays a second image obtained by converting a first image on the display unit. The second image is an image obtained by converting the first image based on at least the identification range. The first image is generated based on an intensity signal of light detected by a PPD and a scanning position by the scanner.

摘要： The invention relates to a method and device for generating an overview contrast image of a sample carrier in a microscope, which images a sample arranged on the sample carrier. The sample carrier on which the sample is located is illuminated in transmitted light from a two-dimensional illumination array, which has individually switchable single light sources and illuminates the sample volume in transmitted light, and a processing unit, which activates and reads out the camera in order to record multiple different raw overview images of the sample carrier.

摘要： A device includes an electronic processor configured to define a first set of sample pixels from a set of sample pixels determined from received video data according to a first electro-optical transfer function (EOTF) in a first color representation of a first color space; convert the first set of sample pixels to a second EOTF via a mapping function, producing a second set of sample pixels according to the second EOTF; convert the first and second set of sample pixels from the first color representation to a second color representation of the first color space; determine a backward reshaping function by repeatedly applying and adjusting a sample backward reshaping function so as to minimize a difference between predicted pixel values obtained by applying the sample backward reshaping function to the pixels of the converted first set and the pixels of the converted second set.

摘要： A production monitoring and analysis method based on an image data algorithm includes: obtaining a reconstructed gray histogram according to a gray image of an image where a product identification code is located; obtaining a segmentation threshold of an Otsu algorithm for segmenting the reconstructed gray histogram, obtaining the adjustment of the gray level in the sub-gray histogram according to the number of pixels corresponding to each gray level in the reconstructed gray histogram and the segmentation threshold, correcting the sub-gray histogram to obtain a corrected sub-gray histogram according to the adjustment of the gray level in the sub-gray histogram, the lateral segmentation threshold of the sub-gray histogram, and all the gray levels greater than the lateral segmentation threshold, and obtaining an enhanced gray image according to the corrected sub-gray histogram. The method avoids the loss of original information when using histogram equalization for image enhancement.

摘要： An imaging apparatus includes at least one memory and at least one processor which function as: an exposure control unit configured to perform exposure control so that a representative brightness of a high brightness region of an image becomes a target brightness set by a user; and a tone correction unit configured to perform tone correction on a captured image, which was captured after performing the exposure control, based on a brightness of a dark portion that is a region having a brightness lower than the high brightness region, wherein the tone correction unit adjusts a correction amount of the tone correction so that the representative brightness of the high brightness region, which is corrected to be higher than the target brightness by the tone correction, becomes close to the target brightness.

摘要： An image generation method includes: an original image is converted into an image to be processed under a specific scenario; in the image to be processed, a region to be adjusted of which image rendering state does not match scenario information of the specific scenario is determined; the image rendering state of the region to be adjusted is related to light illuminated on a target object in the original image, and the target object includes a vehicle; a target rendering state in the region to be adjusted is determined; the target rendering state matches the scenario information; and in the image to be processed, the image rendering state of the region to be adjusted is adjusted to the target rendering state, to obtain a target image.
