Abstract

The invention discloses a partial color transferring method and a transferring device based on color classification, wherein the method comprises the following steps: classifying pixels of an original image, segmenting an image target area with the color transferring, correcting boundaries of the image target area, and conducting the color transferring to pixels of the image target area with the boundaries corrected. According to the partial color transferring method and the transferring device based on color classification, precise image area segmentation can be achieved, the color transferring can be conducted to the image target area precisely according to expectation of a user, an image enhancing effect is effectively achieved, a natural image effect is achieved, and meanwhile consumption in a color transferring process is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a local color transfer method based on color classification and a device thereof. Background technique [0002] With the popularity of digital multimedia, the technology of quickly and intuitively editing digital content is becoming more and more important in daily life. This content editing is usually a change to the image content (such as color, brightness, contrast), and can be global or local. Because most end users are not professional photographers or designers, they just want to enhance the unsatisfactory areas in the image, but it is not an easy task to directly apply some image post-processing tools to directly enhance the image. Because usually such tools can only be used for global editing of the image, for example, if the user individually edits the color of the flower in the image, then the green leaf color of the background will also be transferred at the ...
