Embodiment Construction

[0029] First define the abbreviations that will be used in the following instructions: Raw image set I i = {1,...,n}, importance atlas S i ={1,...,n},

[0030] figure 1 It is the basic flow chart of the present invention. The invention uses a series of images as input, and through a series of processing, obtains a collage with a certain viewing effect that maximizes the information conveyed. The various processes of the present invention are described in detail below:

[0031] 1. Importance map detection

[0032] Here we input a series of original image collections, through steps such as color detection, depth of field analysis, and composition analysis, extract the important area of ​​the image, which is represented by a rectangle. For the convenience of later angle rotation, we expand the area of ​​​​the important area here, and the expansion ratio is 5% of the image's length and width, so as to ensure that important parts are not blocked after the image is rotated.

Abstract

The invention discloses a method for automatically generating and intelligently managing image collage based on importance detection. The method is characterized by comprising the following steps of: (1) performing image importance detection, namely extracting an important area of the image by employing the steps of color detection, depth of field analysis, composition analysis and the like; (2) performing intelligent arrangement, namely arranging the image on a canvas using an algorithm according to the obtained important image in the last step, wherein the important part is guaranteed to be not blocked in the arrangement process; and (3) diversifying the angle, namely supporting the angle diversity to have a positive effect to collage appearance through user-study. Therefore, an angle of each arranged image complying with a certain distribution is given. The generated collage has high information content, so that the integral information of a user is maximized; and meanwhile, the generated collage is basically filled with the canvas, so that the canvas has high utilization rate.

Description

technical field [0001] The invention relates to an automatic generation and intelligent management method of an image collage based on importance detection. Background technique [0002] With the development of digital cameras, more and more digital photo albums are widely used, such as Google's Picasa and Yahoo's Flickr; due to a large number of images, a problem arises, how to effectively display these images There are currently many Products like a way to provide some simple image slideshows. However, these methods not only give up semantic information, but also have unsatisfactory effects. Based on the above, we propose an automatic generation and intelligent management method of image collage based on importance detection. Contents of the invention [0003] The technical problem to be solved by the present invention is how to make the generated collage contain as much information as possible, that is, how to maximize the overall information obtained by the user and ...
