Problems solved by technology
[0003] However, the progress of research on hair at this stage is extremely slow. At present, there is basically no relevant prior art on hair color transformation, and the segmentation technology and method for hair parts are not mature, and there are still errors in the segmentation of edge parts.

Embodiment Construction
[0072] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0073] figure 1 It is a flowchart of a hair color conversion system based on image color segmentation provided by an embodiment of the present invention. First, obtain a new image, preprocess the image, and change the effect of the image by changing the brightness and contrast of the image to improve the effect of hair color transformation; secondly, perform background filtering on the image, and replace the multi-color background with white In order to avoid the influence of background variegated colo...

The invention provides a chromogenic transformation method based on image color segmentation, and the method comprises the steps: S1, collecting an image, and carrying out the preprocessing of the image; s2, performing background filtering processing on the preprocessed image obtained in the step S1; s3, carrying out face recognition and eye recognition on the portrait in the image obtained in thestep S2, further segmenting a hair module, and carrying out shielding processing on eye parts; s4, extracting a plurality of pixel points of the color emitting pixels in the original image, solving an average value of the plurality of pixel points to replace the color emitting pixels, and performing color emitting conversion processing on the image which is obtained in the step S3 and is subjected to shielding processing based on the replaced color emitting pixels; and S5, carrying out background recovery processing on the image after color development transformation obtained in the step S4.Meanwhile, the invention provides a chromogenic transformation system based on image color segmentation and a terminal. The technology is simple to operate, interference can be effectively eliminated,and color development conversion can be rapidly and accurately achieved.
Description
technical field [0001] The present invention relates to the technical field of computer image processing, in particular to a color conversion method, system and terminal based on image color segmentation, and is an image processing method for image segmentation and color conversion. Background technique [0002] With the continuous improvement of computer performance and the continuous development of image acquisition equipment, the application of images has penetrated into people's daily life, production and consumption, and scientific research and other fields. The detection, representation, analysis, and use of hair features have also received extensive attention and research, but hair is an important feature of human appearance, and hair analysis has at least two potential application areas: human recognition and facial image indexing. However, because hair appearance and attributes can change so easily, they are widely considered unstable features for facial recognition...
