Problems solved by technology

In addition, the previous method mainly completed the function of predicting the evaluation results, and could not provide creators with insufficient feature analysis. Therefore, it was difficult to help novices to optimize the video, and they could not solve the practical problems of novices in the production process. Content screening for the platform

Embodiment Construction

[0057] The invention provides an auxiliary method for creating a silent product video driven by audience evaluation data, such as figure 1 shown, the specific steps are:

[0058] S1: Build a product video sample set and a high-quality case library, and mark the obtained initial sample set of product videos through audience evaluation under mute playback. Watch the initial sample set of product videos, and mark the information usefulness and visual comfort of the product video samples through a 7-point scale. Each product video sample collects at least 3 people's annotation data;

[0059] The evaluation labels are the information usefulness label and the visual comfort label. The information usefulness refers to the degree to which the audience can obtain useful information about the product through the video to help purchase decisions; the visual comfort refers to the process of the audience obtaining information from the video. ease and clarity of visual perception;

Abstract

The invention discloses an audience evaluation data-driven auxiliary method for silent product video creation. And build a high-quality case library, build an evaluation prediction model through the XGBoost method, build an evaluation prediction model interpreter through the SHAP algorithm, and select high-quality cases from the high-quality case library that match the materials, video attributes and product types provided by users, and explain them through the prediction model The high-quality features of high-quality cases can be obtained by the interpreter to assist users in completing video creation. The evaluation results of video films can be predicted through the evaluation prediction model, and the features with negative SHAP values ​​of video films and the target value range of feature optimization can be obtained through the model interpreter to assist users. Adjust the eigenvalue of this feature to complete the optimization of the video. This method can provide high-quality reference cases, and evaluate and optimize the video clips produced by users.

Description

technical field [0001] The invention belongs to the technical field of computer vision and computer-aided design, and in particular relates to a method and a device for assisting video creation of silent products driven by audience evaluation data. Background technique [0002] With the upgrade of Internet consumption, the way for merchants to fight for the market is no longer just "price war", but to improve the consumption experience. Therefore, in recent years, intuitive and rich product videos have gradually become the most popular product display method in e-commerce platforms. Product video, also known as the main image video, is located on the first screen of the detail page. Its main function is to help consumers efficiently and comfortably obtain rich and in-depth product information, thereby promoting purchasing decisions. Compared with the graphic introduction of previous e-commerce platforms, product videos have a larger information load and are more in line wit...
