Problems solved by technology

However, for abstract painting images, its content and semantics are more subtle and less obvious than photographic images, so it is more difficult to detect the direction of abstract paintings, and there are relatively few related works in recent years

Abstract

The invention belongs to the technical field of image processing, and particularly relates to an abstract picture direction determination method based on HSI-LBP features. The problem of judging the correct hanging direction of an abstract picture under the condition that no clear direction prompt exists is solved. Specifically, the method comprises the steps: converting a color image of an abstract picture into an HSI model from an RGB model, and averagely dividing the image into a plurality of sub-blocks after the image is rotated by four angles; extracting a local binary pattern LBP descriptor of each sub-block in an H-S mode, and combining LBP coding histograms of peripheral sub-blocks to serve as image features; finally, carrying out automatic direction judgment through a support vector machine (SVM). The method can effectively improve the direction recognition accuracy of the abstract picture, and provides a new research perspective for the research of the abstract picture.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a method for determining the direction of an abstract image based on HSI-LBP features. Background technique [0002] Abstract paintings are created by artists combining visual elements such as points, lines, planes and colors according to their own subjective thoughts, and are generally understood as art that does not describe nature. Abstract paintings generally have two forms of expression, paintings created to express strong emotions and desires are called "hot abstraction", and paintings that only use color and graphics to express structure are called "cold abstraction". When creating an abstract painting, the artist decides the correct direction to hang the work according to his own aesthetic concept. While the correct orientation is usually specified on the back of the canvas, it is not obvious to the lay observer. In response to this problem, some psychological ...
