Embodiment 1

[0026] The present embodiment provides a method for caricature segmentation, which includes the following steps, the flow chart of which is as follows figure 2 shown.

[0027] S100: Divide the input image area.

[0028] In this step, the input image is divided into regions based on user input and texture features, and the region of the input image is divided into an initial region and a non-initial region, wherein the user input includes at least one stroke, and the initial region is the region corresponding to the stroke input by the user The area with similar texture, the non-initial area is the area whose texture is not similar to the area where the user enters strokes; that is, the user only needs to simply draw one or several strokes in the area he wants to divide, and this step can realize the user The area to be segmented is divided into the initial area, and other areas are divided into non-initial areas.

[0029] Specifically, step S100 includes the following steps...

Embodiment 2

[0082] Based on the cartoon segmentation method provided in Embodiment 1, this example specifically applies it to such as Figure 5 The image segmentation shown.

[0083] The system inputs a comic picture, such as Figure 5 As shown in (a), the user uses the brush tool of the system to draw a stroke in the area that he wants to segment in the comic picture, such as Figure 5 As shown in (b), the user is in Figure 5 Draw a stroke on the moon in (b) to indicate that the user wants to Figure 5 The moon in (a) is segmented out, and based on the input strokes of the user, the comic picture is firstly analyzed for texture features by steps S101-S103 in Embodiment 1 to obtain a texture similarity map, as shown in FIG. Figure 5 As shown in (c), the initial area and non-initial area are obtained through the image segmentation algorithm, such as Figure 5 (d), where, Figure 5 The white area in (d) is the initial area, and the black area is the non-initial area. Since the initia...

Abstract

Disclosed is a segmentation method of a cartoon. The segmentation method of the cartoon includes the following steps: dividing areas of an inputted image: dividing areas to the inputted image according to a user inputting the image and based on textural features, and dividing the areas of the inputted image into a primary area and a non initio area; smoothing the inputted image: smoothing the inputted image based on a texture smoothing algorithm, and obtaining a smoothing chart of the inputted image; extending the primary area: extending the primary area based on the smoothing chart so as to obtain a smoothing connection chart; segmenting the smoothing connection chart: segmenting the smoothing connection chart by using a fingerprint image segmentation method, and obtaining texture areas of the inputted image which are accurately segmented. By comprehensive adopting the above textural features and texture smoothing algorithm, the segmentation method of the cartoon not only has capacity of distinguishing textures, but also can obtain accurate edges, and thereby can segment the accurate texture areas from a cartoon picture.

Description

technical field [0001] The invention relates to the field of image segmentation, in particular to a cartoon segmentation method and device. Background technique [0002] With the development and popularization of electronic devices, more and more people are no longer limited to traditional comic books, but are getting used to reading comics with electronic devices. Electronic comics, as a new form of comics, are gradually occupying a larger and larger market share. Comics companies and cartoonists also began to produce electronic comics in electronic form, and converted comic books produced in traditional ways into electronic comics. It's worth noting that converting a comic book to a digital comic is more than simply scanning. Unlike comic books of a certain size, electronic devices such as computers, tablets, and mobile phones have display screens of various sizes. Therefore, comic pages need to be enlarged or reduced to accommodate different sizes of display screens. ...
