Description

Image toning method and system

Technical Field

The present invention relates to the field of image toning technologies, and in particular, to an image toning method and system.

Background

With the progress of the times, the textile industry in China has a great development, and the name of a world textile factory is better achieved while the most basic material requirements of people are met. Under the cooperation of cross-regional and globalization in the textile industry, different enterprises communicate in different places more and more frequently, but when the dyeing requirements are communicated, people do not have a uniform color value protocol to communicate more effectively.

Color is the different perception of the human eye to light of different frequencies, and especially the color is more demanding in the design industry. In the textile industry, when different manufacturers or companies dye, a unified color value protocol is not available during communication. Therefore, the technical scheme is based on meeting the requirements of practitioners, provides a unified speech technology and a unified color value protocol, and the practitioners can effectively communicate and better communicate and cooperate through the technical scheme. The unified color value protocol refers to determining a color pattern.

Color mode is a model that represents a certain color in digital form, or a way to record the color of an image. The method comprises the following steps: RGB mode, CMYK mode, HSB mode, Lab color mode, bitmap mode, grayscale mode, index color mode, bi-tonal mode, and multi-channel mode.

RGB color mode: although there is a range of frequencies of visible light, we do not need to represent the color of each frequency separately when dealing with colors. Since all colors in nature can be obtained by combining different intensities of three color frequencies, red, green and blue (RGB), this is what is commonly referred to as the three primary color principle. Thus, these three lights are often referred to by people as the three primary colors or primaries. Sometimes we also refer to these three primary Colors as Additive Colors, because when we add the frequencies of different lights together, the resulting color will be brighter. The three primary colors are interactively overlapped to generate secondary mixed color: yellow (Yellow), Cyan (Cyan), violet (Purple). This also led to the concept of complementary Colors (complementary Colors). The primary and secondary mixed colors are complementary colors to each other, i.e., colors that are the least different from each other. For example, cyan is composed of blue and green, and red is a missing color, and thus cyan and red constitute complementary colors to each other. In the case of a digital video, it is,

encoding each of the three RGB primaries with 8 bits constitutes about 1677 ten thousand colors, which is what we often say true color. Incidentally, both the television and the monitor of the computer create their colors based on the RGB color pattern.

The CMYK color mode is a printing mode. Four of these letters refer to Cyan (Cyan), Magenta (Magenta), Yellow (Yellow), and Black (Black), respectively, and represent four colors of ink in the printing. The CMYK mode is essentially indistinguishable from the RGB mode, in which colors are produced by mixing of colored light from a light source, and the CMYK mode, in which light from a light source is directed onto paper with C, M, Y, K inks in different proportions, and a portion of the spectrum is absorbed and reflected to the human eye to produce color, but the principle of color production is different. Since C, M, Y, K reflects less light to the human eye and the brightness of the light becomes lower as C, M, Y, K four components increase when mixing colors, all CMYK modes produce colors that are also called subtractive color processes.

HSB color mode: from a psychological point of view, color has three elements: hue (Hue), Saturation (Saturation) and Brightness (Brightness). The HSB color mode is a color mode based on human psycho-perception of color. The method is characterized in that RGB three primary colors are converted into a Lab mode, and the psychological feeling of a person on colors is considered on the basis of the Lab mode. Therefore, the color mode is more consistent with the visual perception of people and is more intuitive. It can be represented by two cone solid models with butt joint of bottom and bottom, wherein the axial direction represents the brightness and changes from white to black from top to bottom; the color saturation is radially expressed and gradually becomes higher from inside to outside; and the circumferential direction shows the change of the color tone, forming a color ring.

The Lab color is converted from RGB three primary colors, which is a bridge for converting from RGB mode to HSB mode and CMYK mode. The color mode consists of one Luminance (luminence) and two color (a, b) axes. The color change is represented by a circular line on a plane formed by color axes, wherein the radial direction represents the change of color saturation, and the saturation gradually increases from inside to outside; the circumferential direction represents the change of the color tone, and each circumference forms a color ring; while different luminance values represent different brightness and correspond to different annular color variation lines. It is a color model with "device independent", i.e. the color of Lab is unchanged, regardless of which monitor or printer is used. Where a represents the range from red to green and b represents the range from yellow to blue.

The bitmap pattern represents pixels in an image in two colors (black and white). The image in bitmap mode is also called black and white image. Since its depth is 1, it is also called a one-bit image. Photoshop provides several algorithms to simulate the details lost in an image, since bitmap patterns represent only black and white pixels of an image, and a lot of details are lost when converting an image into bitmap patterns. The bitmap mode image size is the smallest, about 1/7 for grayscale mode and 1/22 for RGB mode, with the same width, height and resolution.

The gray scale mode can represent the image by using up to 256 levels of gray scales, so that the transition of the image is smoother and finer. Each pixel of the gray scale image has a luminance value between 0 (black) and 255 (white). The gray value can also be expressed as a percentage of black ink coverage (0% equals white, 100% equals black). Images produced using a black-fold or gray-scale scanner are often displayed in gray scale.

The index color mode is a commonly used image mode in the web and animation, and contains nearly 256 colors after the color image is converted into an image of the index color. The index color image contains a color table. If the colors in the original image cannot be represented by 256 colors, Photoshop selects the closest color from the available colors to simulate the colors, so that the size of the image file can be reduced. For storing the colors in the image and creating color indexes for the colors, the color table may be defined during conversion or modified after the index image is generated.

The two-tone mode uses 2-4 color inks to create an image composed of a mixture of tone scales of two tones (2 colors), three tones (3 colors), and four tones (4 colors). In the process of converting a grayscale image to a two-tone mode, the tones can be edited to produce special effects. The main purpose of using the two-tone mode is to represent as many color levels as possible with as few colors as possible, which is important to reduce the printing cost because each additional tone requires a greater cost when printing.

The multi-pass mode is very useful for images with special printing requirements. For example, if only one or two or three colors are used in the image, using the multi-pass mode can reduce printing costs and ensure proper output of image colors. 6.8 bit/16 bit channel mode in grayscale RGB or CMYK mode, 16 bit channels may be used instead of the default 8 bit channels. By default, an 8-bit channel contains 256 levels, and if 16 bits are added, the number of levels per channel is 65536, which can obtain more color details. Photoshop can recognize and input 16-bit channel images, but there are many limitations to such images, all filters cannot be used, and in addition, 16-bit channel mode images cannot be printed.
