Image composition beautifying method and system based on visual area proportion balance rule

Abstract

The invention discloses an image composition beautifying method based on a visual area proportion balance rule. The method comprises the following steps: (1) inputting an image; (2) detecting an area segmentation line of the image and dividing the image into two areas; (3) obtaining an area to be optimized and an optimization strategy of the image by utilizing the visual area proportion balance rule and based on the area segmentation line; (4) calculating texture complexity of the area to be optimized; (5) performing optimization on the area to be optimized based on the optimization strategy, utilizing a rapid seam-insertion method to perform stretching or reducing on the area to be optimized when the texture complexity of the image is smaller than a preset threshold value of the texture complexity, and otherwise, utilizing a sample-based high-efficiency image restoration algorithm to perform stretching on the area to be optimized; and (6) outputting the optimized image. The invention further discloses an image composition beautifying system based on the visual area proportion balance rule. According to the image composition beautifying method and system based on the visual area proportion balance rule, the image composition is automatically beautified and the image is allowed to have a better esthetic visual effect.

Description

Technical field [0001] The invention relates to the field of image intelligent processing, in particular to an image composition beautification method and system based on the law of visual area proportion balance. Background technique [0002] Images are an important carrier for people to record their lives and communicate. With the rapid development of computer technology, more and more image information is shared on the Internet, and more and more attention is paid to the research of image aesthetics. Image works with good visual aesthetics can better show people, objects, scenes, etc., can better convey the author's ideas and mentality, and can also resonate with viewers. Composition is the organization of all graphic elements in an image, involving the relationship, location and layout of people, objects, and scenery. The size and position of the main object, the range of the background area, and the distribution and proportion of different types of background areas all bel...

Problems solved by technology

At present, there are only related researches by Chen Renjie, Zhejiang University, etc. in China. They mainly improve the composition of the image by appropriately cropping or expanding the original image, but they do not pay attention to the composition optimization of each spatial region of the image as a whole.
