Embodiment Construction

[0054] Such as figure 1 As shown, in the flow chart of Embodiment 1 of the computer oil painting generation method of the present invention, the generation method includes:

[0055] S1. Receive the source image to be processed, and judge whether the source image is a color image or a grayscale image, if it is a color image, then perform step S2; if it is a grayscale image, then perform step S3;

[0056] S2. Convert the color image into a grayscale image;

[0057] S3. Taking sampling points in a grid manner on the gray scale image, and making random offsets to the sampling points;

[0058] S4. Based on the gray value of the sampling point, calculate the gradient at the sampling point using an edge operator in the horizontal direction and an edge operator in the vertical direction;

[0059] S5. Calculate the stroke direction according to the calculated gradient;

[0060] S6. Take the sampling point as the center and take the pixels in the 3*3 neighborhood as a window, and use...

Abstract

The invention discloses a generation method of a computer oil painting and a system thereof. The generation method comprises the following steps: receiving a source image to be processed, determining whether the source image is a color image or a grey-scale image, and if the source image is the color image, converting the color image into the grey-scale image; taking a sampling point in a grid mode on the grey-scale image, and carrying out random offset on the sampling point; using an edge operator in a horizontal direction and an edge operator in a vertical direction to calculate a gradient at the sampling point; calculating a stroke direction; using an edge operator in a 45 DEG direction and an edge operator in a 135 DEG direction to calculate edge intensity in a window; determining a stroke radius; taking a pixel value of a corresponding position of the sampling point on the source image as a pixel value of a present brush; drafting the sampling point according to the stroke direction, the stroke radius and the pixel value of the present brush. By enforcing a technical scheme of the invention, when using a computer to generate the oil painting, the method is simple, and efficiency of realization is high.

Description

technical field [0001] The invention relates to image processing technology, in particular to a computer oil painting generation method and system. Background technique [0002] Oil painting is a kind of image stylization. In reality, oil painting is a form of artistic expression that emphasizes the layering and texture effects of the brushstrokes of the depicted scenery, and has strong expressive force and rich color changes. Creating oil paintings by hand requires the author to have a certain art background and artistic creation ability, so computer simulation to generate oil paintings has important application and entertainment value. However, the generation methods of computer oil paintings are too complicated and redundant, and the realization efficiency is not high enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for generating computer oil paintings, which is simple in method and high in i...
