Problems solved by technology

Although this speeds up the retrieval speed, the accuracy is unsatisfactory
One of the reasons is that the feature extraction method adopted by photosketcher has limitations on the position, direction, and size of the image, and the spatial position information of feature points cannot be considered under the BOVW model.
[0004] At present, the existing sketch retrieval technology, the pictures in the image library are often icon pictures or scenes, and no one has searched pictures in natural scenes in daily life.

Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0061] see figure 1 , introducing a sketch-based interactive image search and fusion method proposed by the present invention, said method comprising the following steps:

[0062] (1) The process of building an index file in the image library. The specific content is: segment the source image in the image library into sub-images containing only a single object, and record the mapping relationship; obtain the outline of the object in the sub-image, and use the GF-HOG algorithm (see RuiHu, Mark Barnard, John Collomosse. Gradient field descriptor for sketch basedretrieval and localization. ICIP 2010.doi:10.1109 / ICIP.2010.5649331) to calculate its corresponding feature vector; according to Bagof Visual Words (BoVW, see Sivic J, Zisserman A.Video Google: AText Retriev...

Abstract

An interactive image search and fusion method based on a sketch, comprising the following steps: (1) the process of establishing an index file in an image database; (2) the process of obtaining an image retrieval result based on the sketch; (3) the process of image fusion. Compared with Sketch2Photo, the method of the present invention greatly shortens the overall processing time, and provides more liberalized user interaction. Compared with Photosketcher, the method of the present invention can provide higher retrieval accuracy, and greatly reduce the number of user retrievals, for Users provide more reasonable and rich materials.

Description

technical field [0001] The invention relates to a sketch-based interactive image search and fusion method, which belongs to the field of information technology, in particular to the field of computer vision technology. Background technique [0002] With the popularization of social networks, people's demand for image processing is getting stronger and stronger. Some easy-to-use image processing software has become very popular. Analyzing the reasons behind its success is nothing more than providing a simple and convenient image editing platform for non-professional users. But so far there is no software that provides users with the function of simple and free image synthesis. [0003] As early as around 2010, some researchers have conducted research on the convenient and quick synthesis of an image. The core question is how to obtain the target object and background image conveniently and quickly? There are only two retrieval methods currently available: text-based image...
