Embodiment approach 1

[0053] Embodiment 1: select a preset number of images from product images; identify the logo images of the selected images manually, and measure the size and position of the logo images; make statistics on the size and positions of the logo images of the selected images; The size and position of the logo image of the selected image are counted to determine the size and position of the logo removal area, so that the logo removal area can cover the logo images of the selected image in a preset quantity ratio. Set the pixels in the logo removal area of ​​all product images to a uniform color.

[0054] An application example of Embodiment 1: 1,000 product images are randomly selected from a product image library of 2 million, and a coordinate system is established with the upper left corner vertex of the product image as the coordinate origin (0,0), and the x-axis is horizontally to the right, Vertically downward is the y-axis, manually mark the size and position of the logo image...

Embodiment approach 2

[0056] Embodiment 2: Select a preset number of images from product images; divide the selected images into image blocks, compare the logo images in the logo image library with each image block of the selected image, and identify the selected image according to the comparison result The logo image adopted in the image, and measure the size and position of the logo image; the size and position of the logo image of the selected image are counted; according to the size and position of the logo image of the selected image of the statistics, the size and position of the logo elimination area are determined, so that The logo removal area can cover the logo image of the selected image in a preset quantity ratio. Set the pixels in the logo removal area of ​​all product images to a uniform color.

[0057] An application example of the second embodiment: establish a logo image library, store logo images of the manufacturer or seller in the logo image library, and update and add new logo ...

Embodiment approach 3

[0059] Embodiment 3: Divide the product image into image blocks, compare the logo image in the logo image library with each image block of the product image, identify the logo image used in the selected image according to the comparison result, and measure the logo image Size and position to determine the logo removal area for each product image individually. Select the sample image of the product to be compared, set the pixels in the logo elimination area of ​​each product image to the same color as the corresponding pixel in the sample image or stitch the area corresponding to the logo elimination area in the sample image To the logo removal area of ​​the product image.

[0060] An application example of the third embodiment: establish a logo image library, store logo images of producers or sellers in the logo image library, and update and add new logo images at any time. Each product image is divided into several image blocks, and the size and position of each image block ...

Abstract

The invention discloses a method and device for comparing product attribute information, and relates to the technical field of computers. The same product image is obtained by comparing product images, and the marked product attribute information is compared according to the same product image again, so that the comparison between attributes (such as price) of the same products is realized; the appearance pictures of the same product are basically the same in each electronic business platform, therefore, the accuracy of product attribute comparison is improved; in addition, the tagged image in the product images is removed before comparing the product images, so that the effects of tagged images of different producers and sellers on the comparison results of the product images can be reduced, and thus the accuracy of the product attribute comparison is further improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for comparing product attribute information (such as prices, etc.). Background technique [0002] With the development of Internet technology, online shopping has become an indispensable way of consumption in life. Customers often want to buy cheaper and more cost-effective products. They will compare the same product on various e-commerce platforms, and each e-commerce platform will also compare prices with each other, so as to adjust prices in time to attract more customers. ,Dominate the market. [0003] In the prior art, each e-commerce platform usually determines the same product according to product text description information such as the brand and model of the product, and performs price comparison. However, when the e-commerce platform labels the product description information such as the brand and model of the product, there may be problems such...
