Embodiment Construction

[0037] A visual attention-based real-time video and image abstraction method of the present invention will be described in detail below through embodiments in conjunction with the accompanying drawings. The present invention can be processed in parallel in the graphics card hardware of a home computer.

[0038] Such as figure 1 As shown, a real-time video and image abstraction method based on visual attention, including inputting the real-time video and image to be processed, converting the red, green and blue color space of the real-time video and image to the CIE-Lab color space, Generate the visual attention distribution map, export the function map of the region of interest, use the abstraction method based on the characteristic flow field to obtain the initial real-time abstract video and image, and use the linear interpolation technology to obtain a new real-time abstract video and image, and convert the real-time The videos and images are reconverted from the CIE-Lab co...

Abstract

The invention discloses a method for abstracting real-time videos and images based on visual attention and comprises the following seven steps: inputting the real-time videos and images to be processed, converting red, green and blue color spaces of the real-time videos and images into a CIE-Lab color space, generating a visual attention scatter diagram, deriving a functional diagram of an interest region, adopting an abstracting method based on a characteristic flow field to obtain initial real-time videos and images, adopting linear interpolation technology to obtain new real-time abstracting videos and images, and reconverting the real-time video and the images from the CIE-Lab color space into the red, green and blue color spaces. Each step of the method can be processed concurrently in graphics card hardware of a home computer; the method effectively solves the problem that the prior real-time video abstracting method has even abstract; and the invention provides a simple and intuitive abstracting method for real-time videos and images for laypeople.

Description

technical field [0001] The invention relates to the technical field of computer image and video processing, in particular to a real-time video and image abstraction method based on visual attention. Background technique [0002] Real-time video abstraction provides a simple, fast, and aesthetically pleasing tool for communicating visual information by simplifying low-contrast areas and enhancing high-contrast areas. [0003] When artists want to paint a scene, they don't just paint all the visual information in the scene. Instead, they select only the important information and use their imagination to display it. Lines can describe information effectively and naturally, and have been used by humans for tens of thousands of years. In recent years, abstraction techniques have become more popular because they can make images and videos easier to understand. Some researchers use eye trackers to capture the attention of the people being tested, and propose a non-uniform image ...
