Problems solved by technology

Moreover, the human eye can easily capture these overlays that destroy the structural characteristics of the image, which greatly affects the viewing experience.
So far, there is no algorithm specifically for determining the location of user tags based on image content.

Embodiment Construction

[0020] The method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, a labeling method based on image content, including:

[0022] (1) The image to be processed is converted from the RGB color space to the CIE-Lab color space;

[0023] The RGB color space is converted to the CIE-Lab color space according to the following formula:

[0024] L = 0.299 × R + 0.587 × G + 0.114 × B a = 0.713 × ( R ...

Abstract

The invention discloses a label adding method based on image content, which comprises the steps of: transforming an image to be processed from RGB (Red, Green and Blue) color space to CIE-Lab color space; obtaining the visual importance of each pixel of the image transformed to the CIE-Lab color space; obtaining the mask bitmap information of a label to be added by the rasterization processing ofthe label; seeking a region with least visual importance loss in the image; adding the label to be added to the sought region with the least visual importance loss; and finishing the adding operationof the label of the image. The invention overcomes the picture sheltering resulted from an image key region of the traditional label adding method and can effectively reduce the visual loss of the image after label adding, thereby enhancing the visual experience of the image. The invention can realize parallel processing in graphic card hardware of a home computer and provides a simple, convenient, intuitive and high-efficiency label adding method of images for ordinary non-professional users.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a tag adding method based on image content. Background technique [0002] When people observe and understand images, they tend to be interested in some specific regions in the image unconsciously. The visual quality of the entire image depends largely on the quality of these ROIs, and the degradation of ROIs is sometimes imperceptible. These regions of interest are often image edge regions. Image edges generally refer to the collection of pixels with step-change pixel grayscales in the image. Image edges are very useful for image recognition and analysis. , step properties, shape, etc.), is an important attribute of an image, the most basic feature in an image, and the basis for analyzing and understanding an image. [0003] The change of image edge information means the change of the basic content or structure of the image. At the same time, the masking eff...
