Embodiment 1

[0064] A method of filling color, including:

[0065] Collecting color pictures, the method of collecting color pictures includes hooking the color pictures by means of web crawlers or manually placing the color pictures related to the pictures to be colored; then analyzing the colored areas of the color pictures and their corresponding colors; Decolorize and read its contour map. The method is to outline the line according to the pattern style, and then remove the color in the line. The pattern is the only pattern contained in the collected color pictures, and the above pattern can be called the foundation. Patterns, based on the learning and analysis of basic patterns to distinguish all patterns in rich and complex pictures;

[0066] The confirmation method of the contour map area in the colored area is a closed area composed of several lines; or a closed area composed of several lines and picture boundary lines; and then record the line shape and connection mode of the colo...

Abstract

A video color filling method and device belong to the technical field of video processing, and the method comprises the following steps: collecting a color picture, and analyzing a color region of the color picture and a color corresponding to the color region; establishing a color filling sample model according to the colored area of the color picture and the color corresponding to the colored area; a to-be-filled video data packet is read, the to-be-filled video data packet comprises multiple frames of to-be-filled video pictures, the to-be-filled video pictures are contour diagrams, and each frame of to-be-filled video picture comprises at least one to-be-filled area; and putting the video data packet to be subjected to color filling into the color filling sample model for matching, and filling the color. The video color filling device comprises a reading module, a collecting module, a color filling sample model module and a filling module. Color matching and automatic color filling can be automatically carried out according to the color filling sample model, and rapid and automatic colorization processing of a black-and-white image is realized.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a method and a device for filling color in a video. Background technique [0002] The natural world that people observe in daily life is composed of colorful colors. Rich colors can give people a pleasant aesthetic enjoyment, and at the same time the application of color penetrates into all aspects of people's daily life, so diversified colors have become a necessity and habit of people's lives.
