A computer device obtains a medical image set. The device identifies a difference between the reference medical image and the target medical image to obtain a candidate non-lesion region in the target medical image. The device determines area size information of the candidate non-lesion region as candidate area size information. The device adjusts the candidate non-lesion region according to the annotated area size information when the candidate area size information does not match the annotated area size information, so as to obtain a target non-lesion region in the target medical image.

The present disclosure provides a method of processing an image, a device, and a medium. The method of processing the image includes: performing an image processing on an original image to obtain a component image for brightness of the original image; determining at least one of the original image and the component image as an image to be processed; classifying a pixel in the image to be processed, so as to obtain a classification result; processing the image to be processed according to the classification result, so as to obtain a target image; and determining an image quality of the original image according to the target image.

A display management processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. The input image is first transformed into a perceptually-quantized (PQ) color space, preferably the IPT-PQ color space. A color volume mapping function, which includes an adaptive tone-mapping function and an adaptive gamut mapping function, generates a mapped image. A detail-preservation step is applied to the intensity component of the mapped image to generate a final mapped image with a filtered tone-mapped intensity image. The final mapped image is then translated back to the display's preferred color space. Examples of the adaptive tone mapping and gamut mapping functions are provided.

A print system includes an image processing apparatus and a print apparatus that receives a print job processed by the image processing apparatus and prints an image on a sheet. The print apparatus determines whether or not a print job received from the image processing apparatus is a measurement target for measuring an image printed on a sheet, measures the image on the sheet printed by executing a print job that has been determined to be the measurement target, and transmits the result of measurement to the image processing apparatus. The image processing apparatus generates a print job serving as a measurement target, and upon receiving the result of measurement based on the transmitted print job, applies the result of measurement to a print job to be printed by the print apparatus.

A color conversion correction data generation device includes circuitry that acquires first chromaticity values obtained from conversion target image data and second chromaticity values of sample image data, the conversion target image data being image data to be subjected to color conversion, the sample image data being obtained by reading a printed sample; curve-fits chromaticity value correspondence data to generate color conversion correction data, the chromaticity value correspondence data being data in which the acquired first chromaticity values and the acquired second chromaticity values are associated with each other; and outputs the color conversion correction data for correcting image data obtained by subjecting the conversion target image data to the color conversion.

Luminance data indicating luminance of the print product illuminated by the lighting is calculated and processing for causing a high luminance region to have gradation characteristics is performed.

A minimum luminance value of a display luminance information is larger than a minimum luminance value of a print luminance information. And in a conversion, a luminance value of a dark region of input image data is converted to a luminance value of a dark region of output image data such that a contrast of a dark region that includes the minimum luminance value of the print luminance information becomes closer to a contrast of a dark region that includes the minimum luminance value of the display luminance information.

An image display apparatus displays an image to be printed on a desired printing medium by using a desired printing apparatus. In this process, medium images corresponding to the tint of the printing medium illuminated with one of illumination light fluxes having a plurality of color temperatures are displayed on a specific display with the medium images associated with the color temperatures of the illumination light fluxes, and specification of one of the medium images or the color temperature associated with the medium image is accepted. When the specification is made, an illumination light flux reflecting image having the tint of the image printed on the printing medium by the printing apparatus and illuminated with the illumination light flux having the color temperature corresponding to the specification is displayed on the specific display.

An apparatus for image conversion includes a processor configured to classify a reference region representing a predetermined feature into a shadowed region and an unshadowed region, the reference region being in an aerial image represented in RGB color space; determine a tone correction factor so that a difference between an average luminance of the shadowed region and an average luminance of the unshadowed region in the aerial image represented in predetermined color space to which the color space of the aerial image is converted from RGB color space is less than a difference between an average luminance of the shadowed region and an average luminance of the unshadowed region represented in RGB color space; correct tones of the aerial image with the tone correction factor; and convert the color space of the aerial image from RGB color space to the predetermined color space to generate a color conversion image.

Apparatuses, systems, and techniques to receive, at one or more processors associated with an image signal processing (ISP) pipeline for a camera, an image generated using an image sensor of the camera, wherein the image comprises a plurality of channels associated with color information of the image; process, by the one or more processors, the plurality of channels of the image to generate a plurality of luminance and/or radiance values; generate, by the one or more processors, an updated version of the image using the plurality of luminance and/or radiance values; and output the updated version of the image.
