摘要： The present invention provides an underwater image color restoration method. In the method, 8-bit RGB pixel values of pixels in an underwater image are converted to a linear sRGB space for adjustment processing, adjusted pixel values are converted to 8-bit RGB pixel values, and then the acquired 8-bit RGB pixel values are fused with the adjusted pixel values to obtain a restored underwater image. Therefore, a foreground object in the underwater image or an underwater video processed using the solution of the present invention is natural and rich in color; in addition, the natural blue and green colors of background seawater are preserved, and the viewing effect of an entire picture is improved significantly and is comparable to or even better than the effect that can be achieved in the past after considerable manual toning.

摘要： Methods and systems for determining a tumor volume from image data obtained from a functional scanner. The methods and systems can include identifying a portion within a region of interest corresponding to a liver that varies in intensity with its corresponding neighboring portion by a threshold. The method and systems can further include determining a volume of the portion without identifying a boundary of the portion. The portion can also be tracked over time. The image data can include a scan from a SPECT scanner.

摘要： The present disclosure relates to a machine learning method, to a method and to a device for converting input image data from a plurality of vehicle cameras of a panoramic-view system into optimized or enhanced output image data. The method for converting input image data from a plurality of vehicle cameras of a panoramic-view system into optimized or enhanced output image data includes input image data acquired by the vehicle cameras and having a current brightness or color distribution provided to a trained artificial neural network. The trained artificial neural network is configured to convert the input image data having the current brightness or color distribution into optimized or enhanced output image data having different output brightness or color distribution; and the trained artificial neural network is configured to output the output image data.

摘要： The present invention relates to a method and a system for compensating interference in a charged particle beam microscopy system. A step of capturing data obtained from irradiation of a sample for a sampling duration can be implemented. In the system a respective data storage is provided for capturing and/or storing this data. Further steps of dividing at least representative parts of the sampling duration into time-windows and constructing, for each of the time-windows, an intermediate image, can be implemented. Detecting shift between the intermediate images and determining a compensation function for the shift between the intermediate images is realized as well. In a system the latter steps are automated by a respective processing component. The shift between intermediate images can be a two-dimensional shift and the compensation function represents a shift of the intermediate images in the two dimensions over time.

摘要： A method for correcting interference fringes includes: obtaining interference fringe images with different photographing distances; obtaining a to-be-corrected image including to-be-corrected pixels, and calculating a depth value of each to-be-corrected pixel in the to-be-corrected image; selecting, from the interference fringe images with different photographing distances, an interference fringe image corresponding to the depth value of each to-be-corrected pixel as a target interference fringe image; extracting first pixel values of target coordinate positions in the target interference fringe image; and correcting second pixel values of to-be-corrected pixels according to the first pixel values corresponding to the to-be-corrected pixels to obtain a corrected image.

摘要： Provided are a method and device for image processing, a terminal device and a storage medium. The method includes: a high-brightness region is determined based on brightness of pixels in a first image, the brightness of the pixels in the high-brightness region being higher than the brightness of the pixels around the high-brightness region; a diffraction region in the first image is determined based on the high-brightness region, the diffraction region being an image region around the high-brightness region; and brightness of the diffraction region is reduced to obtain a second image. Through the method, after the brightness of the diffraction region is reduced, an overlap image formed by diffraction is alleviated, and the image is more real.

摘要： A scene-based image processing method includes: performing decoding after acquiring video data to obtain multiple image frames, and identifying key frame images by performing key frame detection (S10); analyzing similarity between the content of two adjacent key frame images, and determining whether the difference in the content of the two adjacent key frame images is within a preset threshold (S20); and when the difference in the content of the two adjacent key frame images is within the preset threshold, determining that the two adjacent key frame images are a same scene, uniformly performing image feature statistics compilation, overlaying feature information, and performing image enhancement on a same scene by using a similar enhancement processing curve (S30).
