Embodiment Construction

[0033] Below, the present invention is further described.

[0034] The specific implementation of this embodiment is carried out under the following conditions:

[0035] A. Test data set: SCC-125 data set (real cloth image data collection with simple color features), the total number of data records is 125×4=500; CCC-125 data set (real cloth image data with complex color features collection), the total number of records is 125×4=500.

[0036] B. Data preprocessing: The data is not normalized, and the weight factors between each feature are not considered.

[0037]C. Similarity Calculation Formula: The similarity is calculated using the quadratic distance.

[0038] D. Threshold: This test does not consider threshold information, the main purpose is to detect and compare the color feature representation method proposed by the present invention, that is, the color representation method based on the main color weight histogram (denoted as: MCWH) and other three classic The hist...

Abstract

The invention relates to a fabric image color feature extraction method. According to the method, a color space quantification improvement method based on an essential color clustering method is provided during image color quantification grading, so that gray level quantification is better conducted on the color of each pixel in an image; meanwhile, the essential color histogram of the image and the color ratio information of each essential color are extracted with the essential color weight histogram, so that the accuracy of fabric image retrieval is improved and a fabric image meeting requirements of users is retrieved efficiently.

Description

technical field [0001] The invention relates to image processing technology, in particular to a cloth image color feature extraction method. Background technique [0002] Luggage companies need to purchase raw materials frequently and in large quantities, and many fabric supply stores often need to find various fabrics that meet customer needs from a large number of fabric color cards. Using manual methods to compare the fabric color cards that need to be purchased has problems such as time-consuming, labor-intensive, and error-prone. It is easy to cause the raw materials actually needed by the enterprise to be inconsistent with the purchased raw materials, and normal production cannot be carried out, which seriously affects the enterprise. Production efficiency and economic benefits. Simultaneously, also bring a lot of inconveniences to cloth supply store. Therefore, enterprise purchasers and fabric supply stores urgently need a computer application system for convenient ...
