Problems solved by technology

These photos are usually taken in natural scenes, and these clothing images may be affected by factors such as background, light, angle, occlusion, etc., making the whole scene of shopping images more complicated
This makes content-based shopping image searches extremely difficult

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to this embodiment.

[0020] Step 1: Image upper body detection

[0021] Use the upper body detector to locate the upper body area in the image to obtain the upper body area where i represents the i-th image. Positioning results such as figure 2 shown in the second row.

[0022] Step 2: Collaborative calculation of image salient regions

[0023] For any image in a set of clothing images, the upper body area of ​​the human body in other images According to its position and image size relationship, it is mapped to the image to form multiple candidate frames of salient regions, such as figure 2 shown in the third row.

[0024] For each candidate frame in the image, the area outside the frame is regarded as the background area, and the area inside the frame is regarded as the unknown area. ...

Abstract

The invention discloses a shopping image collaborative segmenting method for performing collaborative segmentation on a plurality of input shopping images containing one piece of garment automatically and extracting garment areas in the images. According to the invention, foreground (garment) areas and background areas in the shopping images are positioned by using an upper body detection algorithm and an image distinctive area detecting algorithm; a Gaussianmixed model is adopted for performing unified modeling on the foreground and the background of all the garment images and a collaborative segmentation objective function is established; then a minimum cut algorithm is used for performing iteration solving of the objective function; and finally the segmentation results of all the images are obtained. The method is suitable for being applied to e-commerce websites and online shopping websites. Interference on image retrieval caused by complex background can be eliminated and searching accuracy of searching engines can be improved.

Description

technical field [0001] The invention relates to image processing and search engine technology, in particular to a collaborative segmentation method for multiple images containing the same clothing on a shopping website. Background technique [0002] Visual search of shopping images has been a research hotspot in academia and industry in recent years. However, problems such as shopping image background clutter, multi-object coexistence, and object occlusion make large-scale image search a challenging research topic. [0003] E-commerce and online shopping sites, such as Taobao, Amazon, Tencent Paipai, etc., usually have a large number of shopping pictures containing people (such as models). After seeing or searching a large number of product images, customers can learn the details and various aspects of the product by clicking the link of the product they are interested in. [0004] At the same time, in order to fully display the wearing effect of clothing, shopping website ...
