Embodiment Construction

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] The embodiment of the present application provides a weight-based image processing method, which can filter sample data according to the saturation of each image, and then use the logistic regression algorithm to calculate the sample weight value of the sample data, so as to use the obtained sample weight value for pairing The portraits are selected or classified, which can improve the accuracy of the portrait selection or cl...

Abstract

The invention discloses a portrait processing method, a device and an apparatus based on a weight value, wherein the method comprises the following steps: acquiring characteristic data of each portrait and calculating saturation of the characteristic data; According to the saturation degree, the characteristic data which accords with the sample rule is selected as the sample data. Using Logistic Regression Algorithm to Calculate Sample Weights of Sample Data; Extracting a sample portrait corresponding to each sample weight value, and storing the sample weight value and the sample portrait in adatabase corresponding to each sample weight value; The sample portrait is selected or classified according to the sample weight value in the database, and the result is displayed on the display screen. Adoption of the above programme, regardless of whether the saturation value of the portrait feature data is high or low, Logistic regression algorithm can be used to calculate the corresponding weight values of each portrait, so that the portrait can be selected and classified according to these weight values, thus reducing the situation that the accuracy of portrait selection and classification decreases due to the data loss of low saturation portrait.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, device and equipment for image processing based on weight values. Background technique [0002] With the improvement of people's living standards, there are more and more industries serving the masses, and some service companies have more and more employees. In order to facilitate company management, it has become an important part of the company to select or classify these employees according to their portraits. question. [0003] At present, the characteristics of employee portraits are generally used to select and classify. The existing methods use the saturation of the portraits to fill in the low-saturation features or discard them through binary classification. Then screen the required employee portraits according to the degree of saturation, or classify the employee portraits, and then complete the screening and classification of employees. ...
