Description

Image generation method

The present invention relates to image processing; in particular, it refers to a method for generating images.

Traditionally, pictures with patterns are drawn by humans, such as with painting tools or computer software. The combination and arrangement of multiple patterns on the picture create visual beauty, allowing the picture to be used as a work of art. Enjoy it or print it on clothes, shoes, backpacks and other items.

Since traditional pictures are drawn by humans, the production of pictures takes a long time. Moreover, most copyrights of pictures belong to the creator of the picture. If others want to use the picture, they must obtain authorization from the creator before they can use it legally. For example, they need to pay the creator a license fee for the picture, or buy out the picture from the creator.

Traditionally, it takes a long time and money to produce the image and obtain it.

In view of this, the purpose of the present invention is to provide a picture generation method that can replace human beings in drawing pictures by themselves and reduce the cost of obtaining pictures.

In order to achieve the above purpose, the present invention provides a picture generation method, which includes the following steps: A. Obtaining a first pattern quantity and a plurality of first filling units; B. Obtaining a picture; C. Defining an area in the picture Block generation range; D. Generate at least one closed block within the block generation range; E. Fill the generated at least one closed block with a first filling unit to form a pattern; F. Repeat the steps C to E until the number of patterns formed reaches the first number of patterns to form a first picture.

The effect of the present invention is that it can automatically generate pictures with patterns, instead of humans drawing pictures by themselves, and effectively reduce the time and money costs required to obtain pictures.

In order to illustrate the present invention more clearly, the preferred embodiments are described in detail below along with the drawings. Please refer to FIG. 1 , which is a flow chart of an image generating method according to a first preferred embodiment of the present invention. The image generating method is executed by a computer system. The computer system at least includes a computing device.

As shown in Figure 2, a user interface 10 is displayed on a screen connected to the computing device, allowing the user to fill in the required number of first patterns, and using a color palette interface to allow the user to click or select a frame. A plurality of filling blocks 102 on the color palette serve as the required first filling unit. For example, use the left button of a mouse to select the filling block 102 of the first filling unit. In this way, the first pattern quantity and the first filling units can be obtained. In this embodiment, the block filling 102 includes single color, multiple colors, gradient colors, gray scales, materials, graphics, and patterns. Therefore, each first filling unit is a single color, multiple colors, or gradient colors. , grayscale, material, graphics, and one of patterns. After the user clicks the "Output" button image 104, the image is generated. In addition, in this embodiment, the user interface 10 further allows the user to select the number of images to be generated.

Step S02: Obtain a picture. In this embodiment, a picture with blank content is used, as shown in Figure 3. The picture 12 is composed of a plurality of pixels, for example, horizontal pixels × vertical pixels are 3360 × 3840. Of course, it can also be customized by the user. pixels. In one embodiment, the picture 12 may also be a picture selected by the user that already has content.

Step S03: Define a block generation range 14 in the picture 12. In this embodiment, an area is randomly selected in the picture 12 to be defined as the block generation range 14 .

Step S04: Generate at least one closed block within the block generation range 14. Please refer to FIG. 4 , in which (a) to (c) illustrate the steps of generating the closed block 16 in this embodiment. In this embodiment, two anchor points 18 and at least one node 20 are generated within the block generation range 14 , and the at least one closed block 16 is formed based on the two anchor points 18 and the at least one node 20 . More specifically, the positions of the anchor points 18 and the nodes 20 are randomly generated (see Figure 4(a) ), and then a curve taking a spline 22 as an example is formed based on the two anchor points 18 and the at least one node 20 (Refer to Figure 4(b)) But not limited to this, connect the two anchor points 18 to form the at least one closed block 16 (Refer to Figure 4(c)), as shown in Figure 4(c) ), the two anchor points 18 are connected by a straight line, but it is not limited to this. Anchor point 18 and node 20 are only used to illustrate the generation of closed block 16 and will not be shown in the picture. The curve can also be an arc or a Bezier curve.

The number of nodes 20 mentioned above can also be randomly determined to be one, two or more. As shown in Figure 5, two nodes 20 are randomly generated, and the two nodes 20 are connected by a straight line between the two anchor points 18. Opposite sides, thereby forming two closed sections 16 .

As shown in FIG. 6 , at least one other node 24 can be selected within the block generation range 14 , and the two anchor points 18 and the at least one other node 24 form a line 26 as the two anchor points. 18 to form a closed block 16. In one embodiment, as shown in Figure 7 (a) to (c), in order to form two straight lines based on the two anchor points 18 and the at least one node 20, the two anchor points 18 are then connected with a straight line to form Triangular closed block 16.

Step S05: As shown in FIG. 4(d), fill the generated at least one closed block 16 with the first filling unit 28 to form a pattern 30. In this embodiment, one of the first filling units selected by the user in step S01 is randomly selected to fill in the closed block 16 . In this embodiment, the edges of the closed block 16 are not displayed in the picture. After the first filling unit 28 is filled in, the edges of the closed block 16 can be hidden or deleted. In other embodiments, the edges of the closed region 16 may also remain in the picture.

Step S06: Repeat steps S03 to S05 until the number of formed patterns 30 reaches the first number of patterns to form a first picture 32 (refer to FIG. 8 ). The first picture 32 is stored in a storage medium as a picture file. In this embodiment, please refer to Figure 9. In the process of repeating steps S03 to S05, the block generation range 14 selected in step S03 can be allowed to be different from one or more previous step S03. The selected block generation range 14 overlaps at least partially, so that the pattern 30 generated in the current step S05 covers at least a part of the pattern 30' generated in one or more previous steps S05. In this way, the generated patterns 30 and 30' can be partially overlapped, thereby increasing the beauty of the first picture. Preferably, the pattern 30 generated each time has a size and shape different from the pattern 30 generated last time.

After that, the picture generation method of this embodiment further includes repeating steps S01 to S06 a plurality of times to obtain a plurality of first pictures 32, 34, 36 (Figures 8, 10, 11), and the first pictures 32 ,34,36 The positions and shapes of each other’s patterns are different. In this embodiment, the number of repetitions can be determined by the number of pictures input in the user interface.

Right-click or select the filling block 102 of the required second filling unit in the palette interface. Thereby, the second pattern quantity and the second filling units can be obtained. Each second filling unit is one of single color, multiple colors, gradient color, gray scale, material, graphics, and pattern. After the user clicks the "Output" button image 104, the image is generated. Of course, the step of obtaining the second pattern number and the second filling units can also be performed after step S06.

Step S07: As shown in FIG. 14, define another block generation range 42 in the first picture 40. In FIG. 14, the first picture 40 is illustrated by two patterns 30. This step is substantially the same as step S03 , except that an area is selected in the first picture 40 to be defined as another block generation range 42 .

Step S08: Generate at least another closed block 44 within the another block generation range 42. This step is substantially the same as step S04 , except that the at least one other closed block 44 is generated within the other block generation range 42 .

Step S09: Fill the generated at least another closed block 44 with the second filling unit 46 to form another pattern 48. This step is substantially the same as step S05 , except that the second filling unit 46 is filled in the at least one other closed block 44 , and the edges of the other closed block 44 can be retained or deleted. The other pattern 48 covers a part of the original pattern 30 in the first picture 40 and partially overlaps, thereby increasing the beauty of the second picture.

Step S10: Repeat steps S07 to S09 until the number of the other patterns 48 formed reaches the second pattern number, so as to form a second picture 50 (refer to FIG. 15). The second picture 50 is stored in the storage medium as a picture file. In the process of repeating steps S07 to S09, it is possible to allow the generation range 42 of another block selected in step S07 to be the same as the another area selected in step S09 one or more times before it. At least a part of the block generation range 42 overlaps, so that the other pattern 48 generated in the current step S09 covers at least a part of the another pattern 48 generated in one or more previous steps S09 . Thereby, the generated another pattern 48 can be partially overlapped, thereby increasing the beauty of the second picture.

After that, the picture generation method of this embodiment further includes repeating steps S01 to S10 a plurality of times to obtain a plurality of second pictures 50, 52, 54 (Figures 15, 16, and 17), and the second pictures 50 ,52,54 The position and shape of the pattern and the other pattern are different from each other. In this embodiment, the number of repetitions can be determined by the number of pictures input in the user interface 10'. Taking input of 3 pictures as an example, a total of 3 second pictures 50, 52, 54 will be generated. In this way, second pictures 50, 52, and 54 with different patterns can be obtained.

In the third preferred embodiment of the present invention, as shown in FIG. 18 , the patterns 60 formed on the first picture 56 or the second picture 58 have different types of shapes. For example, the shape can be randomly selected from a shape data set selected by the user, and then a closed block is formed and then randomly filled in the first color-filling unit or the second color-filling unit selected by the user.
