Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0064] An embodiment of the present invention provides a method for colorizing a black and white image, the process of which is as follows figure 1 shown, including:

[0065] Step 101: collecting black and white images and converting them into digital formats, and performing preprocessing on the images in digital formats.

[0066] Use image acquisition tools such as digital cameras to obtain black-and-white images in digital format, or use scanners to convert black-and-white photos or drawings into digital formats, and then perform various common image preprocessing, such as reducing or eliminating noise, if necessary, perform grayscale transformation and adjust brightness balance, eliminate image shake for dynamic images, etc. The method for digital ...

Abstract

The present invention discloses a black-and-white image colorization process method, including: adopting the watershed segmentation to segment the black-and-white image into a plurality of closed areas; performing area clustering to the segmented closed areas, to obtain target areas for executing colorization process; calibrating the color of each target area to obtain colorization formwork, executing color stuffing to each target area according to the colorization formwork, to obtain an image completing the colorization process. Meanwhile the present invention also discloses a black-and-white image colorization process system. The black-and-white image colorization process method and system of the embodiment of the invention, adopts the watershed algorithm to segment the closed areas and then uses an area clustering method to obtain target areas, stuffing the color corresponding to each target area into each target area according to the calibrated color formwork, thereby implementing the quick and automatic colorization process black-and-white image.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and system for colorizing black and white images. Background technique [0002] The natural world that people observe in daily life is composed of colorful colors. Rich colors can give people pleasant aesthetic enjoyment, and at the same time, the application of color permeates all aspects of people's daily life, so diversified colors have become a necessity and habit of people's life. [0003] The human eye's ability to distinguish color is much higher than that of black and white grayscale. Therefore, black and white images composed of different black and white grayscales will greatly restrict the expressiveness of the picture due to the lack of color. Since both photography and photography gradually developed into the color era after the era of black-and-white images, many image materials such as photos and movies are limited by the technical conditions of the era in wh...
