  • Publication number: 20220318967
    Abstract: A method and device for image processing, and storage medium are provided. In the method, an initial image I is acquired; a set of m predetermined tone-mapping functions is provided; a pixel I(i) of the initial image is selected; a pixel weight w(i) for the selected pixel I(i) is determined based on pixel information of at least the selected pixel; for each tone-mapping function, a tone-mapping function weight is determined based on the pixel weight; each tone-mapping function is applied to the selected pixel I(i) and weighting the result with the respective tone-mapping function weight; the sum of the weighted result as final pixel I? (i) is determined.

  • Publication number: 20220318966
    Abstract: A method and device for image processing, and storage medium are provided. In the method, an initial image I is acquired; a pixel I(i) of the initial image is selected; a transfer function ƒ is applied to the pixel I(i) to acquire a transferred pixel ?(i), and the transfer function ƒ is determined on the basis of at least the pixel information of the selected pixel; a predetermined tone-mapping function is applied to the transferred pixel ?(i) to acquire a tone-mapped transferred pixel ??(i); an inverse of the transfer function ƒ?1 is applied to the tone-mapped transferred pixel ??(i) to acquire a tone-mapped final pixel I?(i). Herein, the steps are repeated for a plurality of pixels of the initial image I to generate a final image I?, and for each of the plurality pixels the same tone-mapping function is applied.

  • Patent number: 9373187
    Abstract: Method and apparatus for producing a cinemagraph, wherein based on received user input an image from a sequence of images is selected as a baseframe image. The baseframe image is segmented and at least one segment is selected based on user input. A mask is created based on the selected segments and at least one image most similar to the baseframe is selected from the sequence of images using the mask. The selected images are aligned the baseframe image a first cinemagraph is created from the selected images and the baseframe image using the mask.
