Problems solved by technology

On the one hand, the optimal state parameters of each picture are often tightly coupled with the states of several other pictures, causing the update of a certain picture state to affect other pictures globally or locally, resulting in poor scalability of the collage.

Embodiment

[0157] The hardware environment used for testing in this embodiment is: Intel-Core2Duo4.2GHz processor, 4G memory. The software environment is Visual Studio 2010 and Windows7 Professional Edition. The test images come from photos of activities in the group, animated movie posters published on the Internet, and other photos of animals and flowers. During the experiment, they were divided into 9 groups according to the major categories, namely animals, dolls, football players, wine glasses, animated posters, cats and dogs, children, flowers, and girls in gray clothes.

[0158] In this embodiment, depending on the number of pictures in the input picture set, the collage time consumption ranges from several seconds to tens of seconds, and the main calculation time is consumed in face detection and importance map calculation. At the same time, the experimental results of this method and the A user survey was conducted on the results obtained by the "Auto Collage" function (A...

Abstract

The invention discloses a cutting and splicing method of concentration of pictures of a computer. The cutting and splicing method comprises the following steps: 1, estimating an importance degree; 2, dividing sub regions of a display panel to obtain a display of each picture: selecting a group of circles which are the same with the concentration pictures in the number, wherein proportion among initial radiuses of the circles and proportion among the important degrees of each picture are the same, filling the display panel through a circle filling method, after filling is finished, obtaining the sub regions of the display panel through division of circumscribed polygons of the circles, and accordingly confirming a display space Qp, on the display panel, of each picture; 3, optimizing display parameters: determining an orientation angle theta, a putting position and a scaling size of each picture; 4, carrying out seamless fusion rendering. The cutting and splicing method has the advantages of well satisfying objective needs of people on people pictures. Through arrangement of face detection, the displaying of faces is a highest priority, and accordingly the situation that the faces of the people are shielded by display regions of other pictures is avoided effectively.

Description

technical field [0001] The invention relates to a method for cutting and splicing pictures in a computer picture collection, belonging to the fields of computer graphics, multimedia information technology and the like. Background technique [0002] With the increasing popularity of hand-held camera devices, it is more convenient for people to take pictures, and the pictures they get are more abundant, and then the demand for automatic management technology of picture collections is more prominent. As an important image collection summarization and presentation technique, image collage has been receiving more and more attention in recent years. The main purpose of a photo collage is to provide a compact, rich and aesthetically pleasing summary of a photo collection. Since manual production of such a collage summary map requires some professional image editing skills and is time-consuming, automated collage summary map generation technology has become a research hotspot in re...
