A way to turn a picture into an oil painting

Abstract

The present invention relates to the technical field of image processing. The present invention discloses a method for converting a picture into an oil painting, comprising: step 1, performing Gaussian filtering on the input picture, and extracting the luminance channel image of the filtered picture, and generating the direction according to the luminance channel image Flow diagram; Step 2, draw the first layer of oil painting on an empty canvas; Step 3, change the filter parameters, repeat the above steps, and draw another layer of single-layer oil painting on the basis of the previous layer of oil painting, after several times of single-layer oil painting After layer oil painting is drawn, the final oil painting result image is obtained. By filtering the picture to different degrees, images with different degrees of blur are obtained, and oil paintings are obtained by layering and drawing the blurred images. The RGB values ​​of the pixels at the joints between different layers of oil paintings change greatly, and the RGB values ​​of the oil paintings of the same layer are continuous, which makes the picture appear concave-convex and layered, which makes the final oil painting have a strong sense of layering and highlights the effect of oil painting. Greatly meet the needs of users.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for converting a picture into an oil painting. Background technique [0002] Traditional oil painting (an oil painting; a painting in oils) is a painting made on canvas, linen, cardboard or wooden board with quick-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.) kind. The thinners used in painting are volatile turpentine and dry linseed oil. The pigment attached to the picture has strong hardness, and when the picture is dry, it can maintain the luster for a long time. Relying on the hiding power and transparency of the pigment, it can fully express the depicted object, with rich colors and strong three-dimensional texture. [0003] Oil painting is loved by the public for its rich colors and strong three-dimensionality, and its advantages in expressing characters and landscapes are also very obvious. However, oil painting is very professional....
