Embodiment Construction

[0048] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0049] figure 1 It is a system flowchart of a method for interactive color editing of images and videos by using layer decomposition in the present invention. It mainly includes layer color, superpixel segmentation, energy function, calculation of individual pixel weight, interactive color reconstruction.

[0050] Among them, the layer color, because people may have different goals when recombining the color of an image, the user can specify a palette or use the automatic palette, the automatic palette can provide a useful starting point, And it can automatically recombine the color. In order to provide intuitive control for possible color spaces, the model of this method can match th...

Abstract

A method for interactive image and video color editing based on layer decomposition presented by the invention mainly comprises layer color, super pixel segmentation, energy function, single pixel weight calculation, and interactive color reconstruction. The process comprises the following steps: extracting an input image or video; calculating the layer color of input pixels; calculating super pixel segmentation of the image; calculating the layer weight of each super pixel layer; calculating the weight of a single pixel in each layer through linear combination of the weights of a series of single super pixels; and reconstructing an image or video frame using a new color palette, and making real-time feedback about the change of the color palette, so as to realize interactive color reconstruction. The process of chromatographic extraction is cut down. The number of variables in linear solution is reduced. The color mixing layer can be better kept. A good overall effect is achieved in the quality and time complexity of color reconstruction. Interactive editing of images and videos is more convenient.

Description

technical field [0001] The invention relates to the field of image editing, in particular to a method for interactive color editing of images and videos by using layer decomposition. Background technique [0002] Image editing is often used in the fields of graphic design and photography. It performs operations such as color correction and texture repair on images to obtain the desired visual effects. For example, in digital image editing software, you can easily and quickly adjust the light and dark, warm and cold tones of the image. At the same time, when processing the image, you can realistically simulate some texture details to obtain a more realistic image. While existing methods allow for user-interactive color reconstruction while maintaining smooth color mixing, how to more easily perform image editing and interactively modify the final color reconstruction remains a challenging problem. [0003] The invention proposes a method for interactive color editing of imag...
